Perceptions of dengue risk and acceptability of a dengue vaccine in residents of Puerto Rico. Hum Vaccin Immunother 2024; 20:2323264. [PMID: 38599678 PMCID: PMC11008542 DOI: 10.1080/21645515.2024.2323264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 02/22/2024] [Indexed: 04/12/2024] Open
Abstract
Dengvaxia is the first dengue vaccine recommended in the United States (U.S.). It is recommended for children aged 9-16 y with laboratory-confirmed previous dengue infection and living in areas where dengue is endemic. We conducted focus groups with parents and in-depth interviews with key informants (i.e. practicing pediatricians, physicians from immunization clinics, university researchers, and school officials) in Puerto Rico (P.R.) to examine acceptability, barriers, and motivators to vaccinate with Dengvaxia. We also carried out informal meetings and semi-structured interviews to evaluate key messages and educational materials with pediatricians and parents. Barriers to vaccination included lack of information, distrust toward new vaccines, vaccine side effects and risks, and high cost of/lack of insurance coverage for laboratory tests and vaccines. Motivators included clear information about the vaccine, a desire to prevent future dengue infections, the experience of a previous dengue infection or awareness of dengue fatality, vaccine and laboratory tests covered by health insurance, availability of rapid test results and vaccine appointments. School officials and parents agreed parents would pay a deductible of $5-20 for Dengvaxia. For vaccine information dissemination, parents preferred an educational campaign through traditional media and social media, and one-on-one counseling of parents by healthcare providers. Education about this vaccine to healthcare providers will help them answer parents' questions. Dengvaxia acceptability in P.R. will increase by addressing motivators and barriers to vaccination and by disseminating vaccine information in plain language through spokespersons from health institutions in P.R.

Abstract
Despite overall improvements observed at the national level, there is a significant disparity in childhood vaccination coverage rates between urban and rural regions, particularly within tribal and remote areas in Pakistan. Our study aimed to explore the views of community/tribal leaders concerning barriers and their local solutions for improving vaccine uptake, with a specific focus on remote settings. An exploratory qualitative research study was conducted from July to September 2019 in Shikarpur, Sindh, Pakistan. We interviewed 11 community leaders, after developing a semi-structured interview guide based on the health belief model. Following validation, the collected data was transcribed and subsequently translated into the English language. A stepwise process of manual familiarization, coding, theme generation, and theme review using an inductive approach was followed. While most of the rural community leaders expressed a willingness to support vaccinations, numerous unexplored barriers were identified. These barriers included an unsustainable communication system heavily dependent on polio mobile teams, discourteous behavior of healthcare personnel, cultural restrictions that limited women's involvement, economic hardships, limited transportation options, insufficient collaboration with the education sector, poor knowledge among community leaders, and security concerns. Additionally, they proposed some innovative solutions of information dissemination methods through the Ottaque system, ethics-based training, subsidized transportation services or voucher system, and addressing security concerns in collaboration with community leaders. Our findings suggest policymakers take both community leaders and members for an inclusive policy-making process to redraft the special policy for these remote and rural areas.

Abstract
The hepatitis C virus (HCV) is responsible for approximately 50 million infections worldwide. Effective drug treatments while available face access barriers, and vaccine development is hampered by viral hypervariability and immune evasion mechanisms. The CD4+ and CD8+ T-cell responses targeting HCV non-structural (NS) proteins have shown a role in the viral clearance. In this paper, we reviewed the studies exploring the relationship between HCV structural and NS proteins and their effects in contributing to the elicitation of an effective T-cell immune response. The use of different vaccine platforms, such as viral vectors and virus-like particles, underscores their versability and efficacy for vaccine development. Diverse HCV antigens demonstrated immunogenicity, eliciting a robust immune response, positioning them as promising vaccine candidates for protein/peptide-, DNA-, or RNA-based vaccines. Moreover, adjuvant selection plays a pivotal role in modulating the immune response. This review emphasizes the importance of HCV proteins and vaccination strategies in vaccine development. In particular, the NS proteins are the main focus, given their pivotal role in T-cell-mediated immunity and their sequence conservation, making them valuable vaccine targets.

Abstract
PURPOSE To understand motivators, concerns, and factors associated with COVID-19 vaccine initiation for adults in five racial/ethnic communities across Colorado. METHODS Community-based data collectors surveyed participants from five Colorado communities (urban and rural Latina/o/x, urban Black, rural African American immigrant, and urban American Indian) about vaccine attitudes, intentions, and uptake from September to December 2021. Bivariate and multivariable logistic regression models were used to examine factors associated with the primary outcome of COVID-19 vaccine "initiation." RESULTS Most participants (71.1%) reported having initiated COVID-19 vaccination; vaccine series completion was 65.1%. Both motivators and concerns about COVID-19 vaccines were prevalent. Vaccine hesitancy (OR: 0.41, 95% CI:0.32-0.53; p < .001) and low perceptions of COVID-19 vaccination social norms (OR: 0.48, 95% CI:0.27-0.84; p = .01) were associated with vaccine initiation. CONCLUSION Despite the limitation of a moderate sample size, our findings support the need for further interventions to increase vaccination against COVID-19 by reducing vaccine hesitancy and improving perceived social norms of vaccination in underserved Colorado communities. IMPLICATIONS To improve trust in vaccines and promote vaccine uptake, community messaging should be tailored to vaccination motivators and concerns and demonstrate COVID-19 vaccination as the community default.

Int J Hyg Environ Health 2024; 258:114337. [PMID: 38461738 DOI: 10.1016/j.ijheh.2024.114337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 01/19/2024] [Accepted: 02/06/2024] [Indexed: 03/12/2024]
Abstract
BACKGROUND Aluminum (Al) adjuvants have been used in vaccines and subcutaneous immunotherapy (SCIT) for decades. Despite indisputable neurotoxic properties of Al, there is no clear evidence of a causal relationship between their use and any neurotoxic side effects. However, recent rat studies have shown an accumulation of Al from adjuvants in tissues, especially in bones. OBJECTIVES Since the human toxicokinetics of Al-adjuvants are poorly understood, this study aimed to evaluate whether up-dosed or long-term SCIT with Al-coupled extracts leads to increased Al load in humans. METHODS This observational cross-sectional case-control study explored Al excretion in hymenoptera venom allergy patients recruited in 2020 before initiation (n = 10) and during ongoing (n = 12) SCIT with Al-based preparations. Urine samples were collected before and 24 h after the SCIT injections and analyzed for aluminum content by using atomic absorption spectrometry. The cumulative administered Al dose was extracted from patient records. Patients receiving long-term immunotherapy were treated between 2.8 and 13.6 years (mean 7.1). Other potential sources of Al exposure were surveyed. RESULTS Patients who had received Al-coupled immunotherapy for several years showed significantly (p < 0.001) higher Al excretion than the controls at initiation of immunotherapy (mean 18.2 μg/gC vs. 7.9 μg/gC) and predominantly (73%) were above the 95th percentile of the general populations' exposure (>15 μg/gC), however, without reaching levels of toxicological concern (>50 μg/gC). Taking both groups together excreted Al levels correlated with the cumulative administered Al dose from SCIT (linear regression: Alurine = 8.258 + 0.133*Alcum; p = 0.001). DISCUSSION These results suggest a relevant iatrogenic contribution of long-term SCIT to human internal Al burden and potential accumulation. Considering the medical benefits of Al-adjuvants and SCIT a differentiated risk-benefit analysis is needed. For certain scenarios of potential toxicological concern in clinical practice biomonitoring might be advisable.

Abstract
Background Vaccine hesitancy among parents directly affects the child's vaccination status since they are the legal decision-makers regarding vaccinating their children. The study aimed to describe the perceptions of highly educated Kazakhstani mothers about childhood vaccination hesitancy. Methods The study utilized a thematic analysis to explore the mothers' perceptions. A sample of 95 participants comprehensively answered the free-text questions in an online questionnaire from January to February 2023. The analysis of the free-text responses followed a semantic thematic analysis approach. The data were coded manually. Results From the in-depth analysis of the data, 285 initial codes were extracted. The combination of similar meanings and concept codes led to 14 sub-themes and finally yielded four significant themes: misconceptions about childhood vaccination, fear of the effect of vaccine on children, distrust of the healthcare system, and social learning factors. Conclusion The perceptions of Kazakh mothers about childhood vaccination hesitancy may lead to behaviors of delaying and refusing some or all childhood vaccines. Therefore, motivational and educational strategies can be used by healthcare providers to instill trust in parents about childhood vaccines and their safety and effectiveness.

Abstract
We aimed to investigate the willingness of hospital staff to receive the COVID-19 vaccine and explore the associated factors and reasons of vaccine hesitancy among Chinese hospital staff, which were not yet known. A cross-sectional questionnaire survey was conducted online on the vaccine hesitancy of staff in a grade A tertiary general hospital in Beijing from February 22 to 23, 2023. Univariate and multivariate logistic regression were used to assess associations between potential influencing factors and vaccine hesitancy. A total of 3269 valid respondents were included, and the rate of COVID-19 vaccine hesitancy was 32.67%. Multivariate logistic regression showed that women [1.50 (1.22-1.83)], having high-school education level [1.69 (1.04-2.76)], college degree [2.24 (1.35-3.72)] or graduate degree [2.31 (1.33-4.03)], and having underlying disease [1.41 (1.12-1.77)] were associated with a higher rate of COVID-19 vaccine hesitancy. The main reasons for vaccine hesitancy included doubts for the safety and effectiveness of COVID-19 vaccine and worries in adverse reactions. Hospital staff's willingness to vaccinate COVID-19 vaccine is generally high in the study. Hospitals should spread the knowledge of COVID-19 vaccine through multiple channels to improve the cognition of hospital staff and encourage vaccination based on associated factors.

Abstract
Background The May 2022 global outbreak of monkeypox (MPX) poses a threat to the health of men who have sex with men. However, there is limited data on the willingness of MSM to receive monkeypox vaccination in Southern China. This study aimed to assess the knowledge of MPX, concerns regarding MPX, and willingness to receive monkeypox vaccination, as well as their correlates, among MSM in China. Methods We conducted a Web-based online survey of MSM in Southern China from August to September 2022. Data were collected on the socio-demographic characteristics, knowledge, worries, concerns regarding MPX and willingness to receive monkeypox vaccination. Multivariate logistic regression was employed to explore the factors associated with willingness to receive monkeypox vaccination. Results A total of 1903 participants completed the survey. Among them, approximately 69.9% reported being aware of MPX awareness, 94.1% of the participants supported the promotion of monkeypox vaccination. The majority of participants (91.4%) expressed their willingness to receive monkeypox vaccination. Participants who considered monkeypox vaccination safe [adjusted odds ratio (aOR) = 4.82, 95% CI: 1.35-17.18], agreed on the necessity of government promotion of monkeypox vaccination in China (aOR = 6.03, 95% CI: 1.07-33.93), believed in prioritizing monkeypox vaccination for MSM (aOR = 5.01, 95% CI: 1.10-22.71), and had friends or sexual partners who had already received the monkeypox or smallpox vaccination (aOR = 10.37, 95% CI: 2.11-50.99) are more likely to be vaccinated. Conversely, married individuals (aOR = 0.13, 95% CI: 0.03-0.47), those engaging in anal sex 4-6 times per week in the past 3 months (aOR = 0.26, 95% CI: 0.09-0.77) expressed hesitancy toward monkeypox vaccination. Conclusion There was a high willingness to receive monkeypox vaccination among MSM in China. The hesitancy toward the monkeypox vaccine can be effectively mitigated by addressing concerns about its safety and potential adverse reactions. Moreover, increasing acceptance of the monkeypox vaccination among MSM and their peers is crucial, as social influence significantly impacts vaccine attitudes and behaviors.

Abstract
More than 6 million people have died due to the COVID-19 pandemic. In order to slow down the spread of COVID-19, health authorities have created numerous guidelines. In the current study, we use survey data from the U.S. and social cognitive theory (SCT) to examine the associations among self-efficacy, outcome expectancies, and willingness to perform recommended COVID-19 related health behavior. Considering the misinformation-filled information ecology during the pandemic, we also examine the moderating role of misperceptions in these relationships. Our findings show that in general the SCT hypotheses hold for COVID-19 related behavior willingness. The interaction effects with COVID-19 misperceptions show that self-efficacy is not enough to understand people's health behavior. Higher outcome expectancies are important and may be able to overcome even if people held high misperceptions. Our findings have direct implications for communication theory and for health organizations in the contemporary information ecology.

Abstract
This study aimed to explore the contextual factors that may be associated with missed opportunities for vaccination (MOV) from the perspectives of healthcare providers and caregivers attending primary healthcare facilities in the Cape Town Metro Health District, South Africa. The ultimate goal of the assessment was to help inform the design and implementation of a contextually appropriate quality improvement programme targeted at reducing MOV in primary healthcare settings. We used a theory-informed exploratory qualitative research design involving focus group discussions with caregivers of children aged 0-23 months; and in-depth interviews of facility staff. A thematic template analysis approach, integrating the theoretical domains framework (TDF) and the capability, opportunity and motivation model of behavior (COM-B) was used to code and analyze the data. Three focus group sessions were conducted, each consisting of 5-8 caregivers and five in-depth interviews involving facility staff. Capability factors comprised caregivers' knowledge, attitude and behavior toward children's immunization. Opportunity factors included the organization of immunization services, long waiting time, vaccine stock out, staff shortage and health workers' attitude, knowledge and capability to assess children's immunization status and needs. Motivation factors included optimism and beliefs about immunization, fear of vaccine-preventable diseases and immunization safety concerns. This study identified important caregiver-, provider- and health system-related factors, which influence immunization outcomes; offering useful contextual insights for informing quality improvement strategies for reducing MOV at primary healthcare level.

Willingness to accept human papilloma virus vaccination and its associated factors among parents with eligible daughters in Addis Zemen town, Northwest Ethiopia. Infect Agent Cancer 2023; 18:84. [PMID: 38129887 PMCID: PMC10740298 DOI: 10.1186/s13027-023-00551-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 10/31/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Cervical cancer is one of the most common cancers in women. Evidences show that, routine immunization of girls at age 14 year and immunization of girls at age 9 year through a 5 years extended interval between doses are the most efficient to control the disease. Despite this, there is very little information on parents' willingness to accept the human papilloma virus vaccine. Therefore, assessing willingness to accept human papilloma virus vaccination and its associated factors among parents with eligible daughter will help to designing, implementing and monitoring effectiveness of HPV vaccine immunization program. METHODS A community-based cross-sectional study was conducted among 386 parents with eligible daughters from 8July-6August, 2022. The multistage sampling technique was used. Data was collected using an interviewer-administered questionnaire. Responses were coded and entered into the computer using EPI data version 4.606 statistical packages, and SPSS version 23 was used for data analysis. Frequencies, percentages and means were as to describe the study variables in relation to the participants. Bivariable and multivariable logistic regression were employed. The statistical significance was set at a p-value of < 0.05 with its respected odds ratio. RESULTS A total of 386 study participants were included in the study. Among participants, 80.3% (95% CI: 76.3, 84) were willing to vaccinate their daughters for HPV vaccination. The parents' willingness was affected by the male parents ([AOR = 3.5; 95% CI (1.673-7.371)], fear of side effects [AOR = 0.385; 95% CI (0.206-0.718)], and with poor awareness on the HPV vaccine [AOR = 0.483; 95% CI (0.259- 0.900)]. CONCLUSION The study has shown that willingness to accept the HPV vaccine is about 80% and significantly affected with parental sex, information on the HPV vaccine, and fear of side effects. As such, it may be helpful for the health care providers and the health care policy makers to emphasize on providing easily understandable information using mass media and social campaign. In addition giving trainings more targeted to female parents might be important.

Abstract
The significant impact of Chlamydia trachomatis(Ct) infections worldwide highlights the need to develop a prophylactic vaccine that elicits effective immunity and protects the host from the immunopathological effects of Ct infection. The aim of this study was to evaluate a vaccine based on a fragment of the Polymorphic membrane protein D (FPmpD) of C. trachomatis as an immunogen using a heterologous DNA prime-protein boost strategy in female mice Three different formulations were evaluated as protein boost: free recombinant FPmpD (rFPmpD) or rFPmpD formulated with a liposomal adjuvant alternatively supplemented with CpG or a cationic gemini lipopeptide as immunostimulants. The three candidates induced an increase in the cervicovaginal and systemic titers of anti-rFPmpD antibodies in two strains of mice (BALB/c and C57BL/6), with no evidence of fertility alterations. The three formulations induced a rapid and robust humoral immune response upon the Ct challenge. However, the booster with free rFPmpD more efficiently reduced the shedding of infective Ct and prevented the development of immunopathology. The formulations containing adjuvant induced a strong inflammatory reaction in the uterine tissue. Hence, the prime-boost strategy with the adjuvant-free FPmpD vaccine formulation might constitute a promissory candidate to prevent C. trachomatis intravaginal infection.

Abstract
BACKGROUND The COVID-19 pandemic has spread over the world. The ability to achieve sufficient immunization coverage to end the global pandemic depends on the acceptance of the COVID-19 vaccine, but it has faced a major challenge around the world. In low-income and developing countries, 22.7% of the population has received at least one dose of the Covid-19 vaccine, which means that a large percentage of the population are unvaccinated, even though they have access to the Covid-19 vaccine so many countries do not accept the vaccine. The aim of this study was to assess COVID-19 vaccine acceptance and its associated factors in Debre Berhan City, Ethiopia, 2022. METHODS A mixed-methods approach comprising both qualitative interviews and a quantitative survey was used among participants in Debre Berhan City. A multi-stage sampling technique was used to recruit the study participants. An in-depth interview was used for the qualitative data. Data was collected by a face-to-face interview questionnaire from June 08 to July 08, 2022. The collected data was entered using Epi Data version 4.6 and analyzed using SPSS version 25. Variables with a p-value less than 0.25 at Bivariable logistic regression analysis were entered into multivariable logistic regression analysis. Logistics regression was employed, and a p-value <0.05 was considered statistically significant. RESULT A total of 765 participants were included in the study, with a response rate of 97.08%. More than half (52.9%) of the respondents had the willingness to accept the COVID-19 vaccine. Participants who had Contact with COVID-19 patient (AOR = 3.98; 95% CI: (1.30-12.14), having good knowledge of COVID-19 vaccine (AOR = 4.63; 95% CI: (1.84-11.63), and positive attitude toward the COVID-19 vaccine (AOR = 3.41; 95% CI: (1.34-8.69) were statistically significantly associated variables with COVID-19 vaccine acceptance. CONCLUSION AND RECOMMENDATION The present study revealed that the acceptance COVID-19 vaccine was 52.9, and a significant proportion of participants were hesitant to receive the vaccine and refused to get vaccinated. Significantly associated Variables for COVID-19 vaccine acceptance were Contact with COVID-19 patient, having good knowledge of the COVID-19 vaccine, and having a positive attitude towards the COVID-19 vaccine. Various stakeholders to apprise the public about the cause of the disease and the scientific development of vaccine in order to enhance acceptance of the vaccine.

Abstract
Hepatitis B viral infection is a significant source of morbidity and mortality worldwide. The United States has experienced a precipitous drop in acute hepatitis B infection after the introduction and widespread adoption of recombinant vaccines. Neonates experience significant risk from both vertical and horizontal hepatitis B exposure during a period of immaturity of the innate and adaptive immune systems. Acquisition of hepatitis B virus at or near birth confers the highest lifetime risk of chronic infection and subsequent complications including liver cirrhosis and hepatocellular carcinoma. Pregnant women should be screened for the presence of hepatitis B surface antigen, indicating acute or chronic infection, and, if positive, hepatitis B viral deoxyribonucleic acid, allowing for quantification of viral load. The development of highly effective and safe recombinant vaccines allows partial protection of late preterm and term neonates immediately after birth. Additionally, administration of hepatitis B immune globulin in the setting of suspected or confirmed exposure supplements the immune response and decreases the risk of chronic infection. The optimal timing of vaccination is later in low-birth-weight neonates due to the aforementioned immune system immaturity. Health care providers serving neonates must familiarize themselves with national guidelines regarding hepatitis B vaccination and hepatitis B immune globulin therapy. Understanding the risks of infection and the evidence basis supporting vaccination and immunotherapy will allow providers to educate families and support decision-making, with the potential to eradicate this vaccine-preventable illness in our lifetime.

Abstract
PURPOSE In the United States (US), individuals vary widely in their readiness to get vaccinated for COVID-19. The present study developed measures based on the transtheoretical model (TTM) to better understand readiness, decisional balance (DCBL; pros and cons), self-efficacy (SE), as well as other motivators for change such as myths and barriers for COVID-19 vaccination. DESIGN Cross-sectional measurement development. SETTING Online survey. SAMPLE 528 US adults ages 18-75. MEASURES Demographics, stage of change (SOC), DCBL, SE, myths, and barriers. ANALYSIS The sample was randomly split into halves for exploratory factor analysis using principal components analysis (EFA/PCA), followed by confirmatory factor analyses (CFA) to test measurement models. Correlation matrices were assessed and multivariate analyses examined relationships between constructs and sub-constructs. RESULTS For DCBL, EFA/PCA revealed three correlated factors (one pros, two cons) (n1 = 8, α = .97; n2 = 5, α = .93; n3 = 4, α = .84). For SE, two correlated factors were revealed (n1 = 12, α = .96; n2 = 3, α = .89). Single-factor solutions for Myths (n = 13, α = .94) and Barriers (n = 6, α = .82) were revealed. CFA confirmed models from EFAs/PCAs. Follow-up analyses of variance aligned with past theoretical predictions of the relationships between SOC, pros, cons, and SE, and the predicted relationships with myths and barriers. CONCLUSION This study produced reliable and valid measures of TTM constructs, myths, and barriers to understand motivation to receive COVID-19 vaccination that can be used in future research.

COVID-19 Vaccination Coverage and Factors Influencing Vaccine Hesitancy among Patients with Inborn Errors of Immunity in Latvia: A Mixed-Methods Study. Vaccines (Basel) 2023; 11:1637.

Abstract
BACKGROUND The European Society for Immunodeficiencies recommends that all patients with inborn errors of immunity (IEI) without contraindications should receive SARS-CoV-2 vaccination. The aim of this study was to investigate the reasons that discourage IEI patients from receiving the recommended vaccination and to assess vaccination coverage among IEI patients in Latvia. METHODS In this multicenter mixed-methods study, the vaccination status of all patients with IEI within two tertiary centers in Latvia was reviewed using electronic health records. Semi-structured interviews were conducted with 16 IEI patients who did not undergo vaccination, and a thematic analysis was performed. RESULTS A total of 341 patients (49.3% female; median age 19.7 years (IQR:17)) were included in the quantitative part. The proportion of fully vaccinated individuals aged ≥ 12 years was 66.8%-70.9% with patients with selective IgA deficiency and 58.8% with other IEI (χ² = 14.12, p < 0.001). The proportion of fully vaccinated individuals aged 5-11 years was 11.1%. Age was associated with vaccination status: younger patients were found to have a significantly lower likelihood of receiving vaccination (U = 8585, p < 0.001). The five main themes identified were as follows: (1) fear and uncertainty; (2) risk and benefit assessment: COVID-19 vaccine-is it worth it? (3) external influences: the dark horse of the decision-making-people around us; (4) individuals against the system; and (5) beliefs about vaccination and COVID-19. Under-representation of certain IEI groups and recall bias are possible limitations of this study. CONCLUSIONS While most reasons for hesitancy were similar to those previously described in the general population, disease-specific concerns were also identified.

Abstract
BACKGROUND In the course of the SARS-CoV-2 pandemic, multiple vaccines were developed. Little was known about reactogenicity and safety in comparison to established vaccines, e.g. influenza, pneumococcus, or herpes zoster. Therefore, the present study aimed to compare self-reported side effects in persons vaccinated against SARS-CoV-2 with the incidence of side effects in persons receiving one of the established vaccines. METHODS A longitudinal observational study was conducted over a total of 124 days using web-based surveys. Persons receiving either a vaccination against SARS-CoV-2 or one of the established vaccines (comparator group) were included. In the first questionnaire (short-term survey), 2 weeks after vaccination, mainly local and systemic complaints were evaluated. The long-term survey (42 days after vaccination) and follow-up survey (124 weeks after vaccination) focused on medical consultations for any reason. Multivariate analyses were conducted to determine the influence of the vaccine type (SARS-CoV-2 vs. comparator) and demographic factors. RESULTS In total, data from 16,636 participants were included. Self-reported reactogenicity was lowest in the comparator group (53.2%) and highest in the ChAdOx1 group (85.3%). Local reactions were reported most frequently after mRNA-1273 (73.9%) and systemic reactions mainly after vector-based vaccines (79.8%). Almost all SARS-CoV-2 vaccines showed increased odds of reporting local or systemic reactions. Approximately equal proportions of participants reported medical consultations. None in the comparator group suspected a link to vaccination, while this was true for just over one in 10 in the mRNA-1273 group. The multivariate analysis showed that people with SARS-CoV-2 vaccination were not more likely to report medical consultations; patients who had received a regimen with at least one ChAdOx1 were even less likely to report medical consultations. Younger age, female gender and higher comorbidity were mostly associated with higher odds of medical consultations. CONCLUSION The rate of adverse reactions after established vaccinations was roughly comparable to previous studies. Two weeks after vaccination, participants in the SARS-CoV-2 vaccination group reported more local and systemic local reactions than participants in the comparator group. In the further course, however, there were no higher odds of medical consultations in either of the two groups. Thus, altogether, we assume comparable safety.

Abstract
The COVID-19 pandemic has been an historic challenge to public health and behavior change programs. In low -and middle-income countries (LMICs) such as Nigeria, there have been challenges in promoting vaccination. Vaccine hesitancy and social norms related to vaccination may be important factors in promoting or inhibiting not only COVID vaccination, but other routine vaccinations as well. The aim of this study was to conduct a national-level quasi-experimental evaluation of a social media based COVID-19 vaccination promotion campaign in Nigeria run in 2022. We followed a longitudinal cohort of Nigerians (at baseline) drawn from all 37 states in Nigeria over a 10-month period. This was done at 3 time points to evaluate psychosocial predictors of vaccination and vaccination outcomes following a theory of change based on Diffusion of Innovations, Social Norms Theory, and the Motivation, Opportunity, Ability (MOA) Framework. In a quasi-experimental design, participants in 6 Nigerian states where the social media campaign was run (treatment) were compared to participants from non-treatment states. This study highlights new social media-based data collection techniques. The study found that vaccination rates increased in treatment states compared to non-treatment states, and that these effects were strongest between baseline and first follow up (December 2021 to March 2022). We also found that more pro-vaccination social norms at one time point are associated with higher vaccination rates at a later time point. Social media campaigns are a promising approach to increasing vaccination at scale in LMICs, and social norms are an important factor in promoting vaccination, which is consistent with the Social Norms Theory. We describe implications for future vaccination campaigns and identify future research priorities in this area.

Abstract
Vaccines play a crucial role in preventing infections in patients with multiple sclerosis (MS), although concerns have been raised about potential worsening of the underlying disease. To investigate this, we conducted a prospective, multicentre, non-randomized observational study assessing changes in disease activity, safety, and clinical tolerability of vaccination in 222 MS patients on disease-modifying drugs. The majority of patients were female (76.6%) and 89.6% had relapsing-remitting MS. The vaccines administered were primarily seasonal influenza (56.3%) or tetanus-based vaccines (33.8%). Disease activity, as measured by annualized relapse rate, decreased significantly from 0.64 the year prior to vaccination to 0.38 in the following year. Moreover, the extended disability status scale remained stable within six months after vaccination in comparison to pre-vaccination values. Side effects were reported in 19.2% of vaccinated subjects, most commonly local side effects (65.2%) or flu-like symptoms (34.8%). Our findings suggest that standard non-live vaccines are safe and well-tolerated in MS patients and do not negatively impact disease activity.

Abstract
Introduction The COVID-19 pandemic has strongly impacted on the immunization services around the world, threatening the gains made in the control of vaccine-preventable diseases. Methods A vaccination recovery plan of missed vaccinations has been put in place in the LHA of Siracusa after the pandemic. We compared 2021 and 2020 vaccination coverage by age group and vaccine type after one year of follow-up of the recovery plan. The Chi-square test was executed on proportions for the years 2021 vs 2020. Results were considered statistically significant at a two-tailed p-value ≤ 0.05. Results 36-month coverage rates were 92.5% for polio and 93.7% for measles-containing-vaccine, representing -0.3% and -1.8% decreases, respectively, as compared to 2020. By 8 years of age (booster doses), immunisation coverage was 80.7% for polio and 80.1% for measles, representing a -5.7% and -3.7%, respectively, compared to 2020. 36-month coverage was 56.6% for Men B (-5.0% as compared to 2020), 73.2% for Men ACW135Y/C (+1.1% as compared to 2020) and 86.9% for PNC vaccine (-1.7%, as compared to 2020). Regarding HPV vaccination, in 2021, vaccine coverage was 44.2% (-4.4% compared to 2020). Compared to the previous report, the VC difference among the cohorts narrowed for all almost vaccinations, except for the anti-men B and the anti-HPV vaccination, for which we recorded an increase in VC difference, and for men ACW135Y/C, for which a significant increase has been recorded. Conclusions Despite the efforts to organize and realize an extensive and well-designed vaccination recovery, our data show that even after the 1-year follow-up, globally deficits in coverage for these routine vaccinations persist, although there has been a substantial and significant recovery of missed vaccinations, especially among younger children and for primary cycles.

Abstract
Analyzing massive VAERS reports without medical context may lead to incorrect conclusions about vaccine adverse events (VAE). Facilitating VAE detection promotes continual safety improvement for new vaccines. This study proposes a multi-label classification method with various term-and topic-based label selection strategies to improve the accuracy and efficiency of VAE detection. Topic modeling methods are first used to generate rule-based label dependencies from Medical Dictionary for Regulatory Activities terms in VAE reports with two hyper-parameters. Multiple label selection strategies, namely one-vs-rest (OvsR), problem transformation (PT), algorithm adaption (AA), and deep learning (DL) methods, are used in multi-label classification to examine the model performance, respectively. Experimental results indicated that the topic-based PT methods improve the accuracy by up to 33.69% using a COVID-19 VAE reporting data set, which improves the robustness and interpretability of our models. In addition, the topic-based OvsR methods achieve an optimal accuracy of up to 98.88%. The accuracy of the AA methods with topic-based labels increased by up to 87.36%. By contrast, the state-of-art LSTM- and BERT-based DL methods have relatively poor performance with accuracy rates of 71.89% and 64.63%, respectively. Our findings reveal that the proposed method effectively improves the model accuracy and strengthens VAE interpretability by using different label selection strategies and domain knowledge in multi-label classification for VAE detection.

Abstract
Vaccine hesitancy is a global health issue and can be affected by several variables. We explored the predictive factors and causes of vaccine hesitancy among adults in Saudi Arabia. An online survey method with multiple regression analysis was used to identify factors predicting of vaccine hesitancy in 558 adults (46.24% women and 53.76% men). The prevalence of vaccine hesitancy is 20.6%, with higher rates among females, young people and single people. About 70% of the participants believe that vaccine hesitancy is due to concerns about the safety and efficacy of the vaccine, a lack of information about the disease and vaccine or social media. The vaccine acceptance rate is 71.3%; 17.2% are not willing to accept a COVID-19 vaccine and 11.5% are unsure. Males and married people are more accepting of the vaccine. The risk factors that predict vaccine hesitancy include age, gender, belief in conspiracy theories and psychosocial factors. Meanwhile, age, gender, belief in conspiracy theories, concerns about the safety and efficacy of the vaccine and psychosocial factors significantly predict vaccine acceptance. The high rate of vaccine hesitancy could undermine efforts to combat COVID-19. Factors predicting vaccine hesitancy can be used in interventions to address this issue during major epidemics.

Abstract
AIMS AND OBJECTIVES To assess the levels of second COVID-19 booster dose/new COVID-19 vaccine hesitancy among nurses and explore the potential predictors of vaccine hesitancy. BACKGROUND COVID-19 full vaccination seems to be highly effective against highly contagious variants of SARS-CoV-2. Healthcare workers are at high-risk group since they have experienced high levels of COVID-19-associated morbidity and mortality. DESIGN An on-line cross-sectional study was carried out in Greece in May 2022, using a self-administered questionnaire. METHODS The study population included nurses in healthcare services who were fully vaccinated against COVID-19 at the time of study. We considered socio-demographic characteristics, COVID-19-related variables, and attitudes toward COVID-19 vaccination and pandemic as potential predictors of vaccine hesitancy. We applied the STROBE checklist in our study. RESULTS Among 795 nurses, 30.9% were hesitant toward a second booster dose or a new COVID-19 vaccine. Independent predictors of hesitancy included lower educational level, absence of a chronic condition, good/very good self-perceived physical health, lack of flu vaccination during 2021, front-line nurses that provided healthcare to COVID-19 patients, nurses that had not been diagnosed with COVID-19 and nurses that had at least one relative/friend that has died from COVID-19. Moreover, increased compliance with hygiene measures, increased fear of a second booster dose/new COVID-19 vaccine and decreased trust in COVID-19 vaccination were associated with increased hesitancy. CONCLUSIONS Our study shows that a significant percentage of nurses are hesitant toward a second booster dose/new COVID-19 vaccine. This initial hesitancy could be a barrier to efforts to control the COVID-19 pandemic. RELEVANCE TO CLINICAL PRACTICE Nurses' role during the COVID-19 pandemic is essential since they are the front-line healthcare workers empowering the public with their passion and empathy. There is a need to communicate COVID-19 vaccine science in a way that is accessible to nurses in order to decrease COVID-19 vaccine hesitancy. PATIENT OR PUBLIC CONTRIBUTION No patient or public contribution.

Abstract
OBJECTIVE Concerns about the side effects of available coronavirus disease (COVID-19) vaccines have posed a significant barrier to vaccination in several countries. Accordingly, the current study aimed to assess the acceptability of COVID-19 vaccination and its predictors among the Lebanese population. METHODS A cross-sectional study was conducted in February 2021 among Lebanese adults from the 5 main Lebanese districts. The questionnaire included demographic data, questions about COVID-19 experience, COVID-19 anxiety syndrome scale, and attitudes regarding the COVID-19 vaccine. Data were analyzed on SPSS, version 23. Statistical significance was considered at a P value ≤ 0.05 with a 95% CI. RESULTS Of 811 participants, 45.4% (95% CI: 41.9-48.9) accepted taking the COVID-19 vaccine. Choices were negatively affected by concerns about the side effects of the vaccine and positively affected by anxiety and seeking COVID-19 news very closely. Moreover, if the COVID-19 vaccination was a requirement for traveling, participants would be more willing to get the vaccine. CONCLUSIONS Since 54.7% of the studied Lebanese adults were either unwilling or undecided to get the vaccine and COVID-19 news was retrieved mainly from the Ministry of Public Health online site and the local news, the existing targeted campaign should be enforced toward encouraging vaccination to reach herd immunity against COVID-19 and revealing the safety of the vaccines.

Abstract
Background Vaccines against COVID-19 are critical for preventing and managing COVID-19 because immunization is one of the most active and cost-effective health strategies for infectious disease prevention. Knowing the community's willingness and factors affecting COVID-19 vaccine acceptance will support the design of effective promotion strategies. Therefore, this study was aimed at assessing COVID-19 vaccine acceptance and its determinants among the Ambo Town community. Method A community-based, cross-sectional study was conducted using structured questionnaires from 1 to 28 February 2022. Four kebeles were selected randomly, and the systematic random sampling procedure was used to select the households. SPSS-25 software was used for data analysis. Ethical approval was received from the Institutional Review Committee of the College of Medicine and Health Sciences of Ambo University, and data were kept confidential. Result Of the 391 participants, 385 (98.5%) of the respondents were not vaccinated for COVID-19, and around 126 (32.2%) of the respondents said that they would receive the vaccine if the government provided it. The multivariate logistic regression analysis revealed that males were 1.8 times more likely to accept the COVID-19 vaccine (adjusted odds ratio (AOR) = 1.8, 95% CI: 1.074-3.156) as compared to females. The acceptance of the COVID-19 vaccine was lower by 60% in those who tested for COVID-19 as compared to those who were not tested (AOR = 0.4, 95% CI: 0.27-0.69). Moreover, the participants who had chronic diseases were two times more likely to accept the vaccine. Acceptance of the vaccine was reduced by half among those who believed that there was a scarcity of data on its safety (AOR = 0.5, 95% CI: 0.26-0.80). Conclusion The prevalence of COVID-19 vaccination acceptance was low. To enhance the acceptance of the COVID-19 vaccine, the government and different stakeholders should strengthen public education using mass media about the advantages of getting the COVID-19 vaccination.

Abstract
Background Vaccination as a fundamental pillar of promoting public health and interest is critical to limiting the COVID-19 pandemic. However, many citizens are still hesitant about this epidemic prevention measure. This article aimed to understand the COVID-19 vaccination and hesitancy rates among Guangzhou residents at different points in time as well as to explore the relevant factors that cause vaccination hesitancy. Methods We conducted a total of nine cross-sectional surveys by enrolling 12,977 questionnaires among Guangzhou residents through the online survey software called "WenJuanXing" between April 2021 and December 2022, and residents made their choices by judging their willingness to vaccinate. These surveys collected data on the participants' sociodemographic characteristics, vaccination status, vaccine hesitancy, and factors influencing this hesitancy. The Chi-squared test was used for univariate analysis and the multivariate logistic regression model was used to further adjust the influence of the confounding factors to evaluate the main factors affecting the hesitancy of the COVID-19 vaccine at different periods. Results Over the course of 2021-2022, a total of 12,977 residents in the study area were surveyed. The vaccine hesitancy rates fluctuated over time. From April to June 2021, the vaccine hesitancy rate decreased from 30% to 9.1% and then increased to 13.7% in November. However, from April to December 2022, the hesitancy rate continued to rise from 13.4% to 30.4%. Vaccination rates, the epidemic waves of COVID-19, and changes in policies may all be possible factors that contributed to these fluctuations in vaccine hesitancy rates. We found statistically significant correlations between factors, such as residence, education, and occupation, and vaccine hesitancy at certain points of time. The results of the surveys in April and June 2021 showed that rural residents showed higher vaccine hesitancy rate than urban residents. Their lower education level was associated with higher vaccine hesitancy. Workers and farmers are more likely to have vaccine hesitancy than people with other occupations. The univariate analysis showed that people with underlying medical conditions and lower perceived health status were more likely to experience vaccine hesitation. Logistic regression analysis revealed that the health status of individuals is the most important factor leading to vaccine hesitancy, and residents' underestimation of domestic risks and overconfidence in personal protection measures were also contributing factors. At different stages, vaccine hesitancy among residents was related to vaccine side effects, safety and efficacy, convenience fluctuation, and various factors. Conclusion In the present study, we found that vaccine hesitancy did not display a consistent downward trend but it fluctuated over time. Higher education, residing in urban areas, lower perceived disease risk, and concerns about the vaccine's safety and side effects were risk factors for vaccine hesitancy. Implementing appropriate interventions and educational programs tailored to address these risk factors may prove to be effective in enhancing public confidence on vaccination.

Abstract
Background The most important factor in combating the coronavirus disease 2019 (COVID-19) pandemic was the provision of safe and effective vaccines. The acceptance of vaccines is impacted by several variables, including beliefs about the vaccine's safety and adverse effects. Vaccine side effects can vary depending on the type, but they are often moderate, localized, transient, and self-limiting. Therefore, this study aimed to assess the prevalence of side effects experienced after receiving the Sinovac vaccine by participants hypertensive and non-hypertensive participants. Methodology This was a cross-sectional, multicenter study that was performed using non-probability sampling. The study duration was six months from May 1, 2022, to October 31, 2022. The study involved 600 individuals who had either received the first or second dose of the Sinovac vaccine. For categorical data, frequencies and percentages were documented. The chi-square test was applied to determine the association between local and systemic side effects among hypertensive and non-hypertensive participants. Results The study findings showed that out of 600 participants, there were 187 (62.3%) males and 113 (37.7%) females with hypertension, and 222 (74.0%) males and 78 (26.0%) females without hypertension, with a significant association (p = 0.002). Following the first dose of the Sinovac vaccine, fever was the most commonly reported side effect in 153 (51.0%) hypertensive participants and 62 (20.7%) non-hypertensive participants, with a significant association (p < 0.001). Similarly, following the second dose of the Sinovac vaccine, fever was the most commonly reported side effect in 108 (36.0%) hypertensive participants and 57 (19.0%) non-hypertensive participants, with a significant association (p < 0.001). Conclusions This study concluded that the presence of hypertension significantly increased the manifestations of local and systemic side effects compared with non-hypertensive participants. Moreover, fever, pain, and swelling at the injection site were the most commonly reported side effects after receiving the first and second doses of the Sinovac vaccine.

Abstract
OBJECTIVES This project's aim was to implement vaccine safety surveillance best practices to improve reporting of adverse events following immunization (AEFI) during coronavirus disease 2019 (COVID-19) vaccination roll out in Uasin Gishu County. INTRODUCTION Weak vaccine safety surveillance systems in developing countries has contributed to underreporting of AEFIs undermining public confidence in immunization efforts, contributing to low uptake of vaccines critical in the fight against communicable diseases. METHODS The JBI Practical Application of Clinical Evidence System (JBI PACES) and Getting Research into Practice (GRiP) audit tool for promoting change in healthcare practice was utilized. Preimplementation and postimplementation audit cycles carried out utilized six best practice recommendations. Context-specific strategies and resources were used to address the gaps identified. RESULTS Less than half of the AEFIs reported were in accordance with the local policy recommendation, and most of the AEFIs reported were submitted in a timely manner in the baseline and follow-up cycle. Slight improvement was recorded in the number of health facilities with AEFIs reporting forms. An improvement of 33.7% was recorded in the number of health workers providing COVID-19 vaccination services who had received education and practical training on vaccine pharmacovigilance. CONCLUSION Underreporting and delayed submission of COVID-19 vaccine AEFI was evident among the healthcare providers offering COVID-19 vaccination services, the majority of healthcare providers had received training on vaccine pharmacovigilance, and AEFI hard copy reporting forms were not adequate in the health facilities. Public education on vaccine safety before administration of vaccine needs emphasis in order to improve reporting of AEFI.

Fujikawa H, Son D, Mori H, Kondo S, Horita S, Izumiya M, Eto M. Development and assessment of a vaccine administration training course for medical students. BMC MEDICAL EDUCATION 2023; 23:385. [PMID: 37231480 DOI: 10.1186/s12909-023-04299-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 04/25/2023] [Indexed: 05/27/2023]
Abstract
BACKGROUND Vaccine administration skills are very important for physicians, especially in the era of global pandemics. However, medical students have reported that practical sessions to develop these skills are insufficient. Therefore, the aim of our study was to develop a vaccination training course for medical students. We also examined its educational effectiveness. METHODS 5th- and 6th-year medical students at the University of Tokyo were recruited to attend the vaccine administration training course in 2021. These students were our study participants. Our course consisted of an orientation part, which included a lecture on the indications, adverse events, and vaccination techniques of flu vaccines and practice on a simulator, and a main part in which the staff of the University of Tokyo Hospital were actually vaccinated. Before and after the main part of the course, study participants completed an online questionnaire that assessed their confidence in vaccine administration technique through a five-point Likert scale. We also surveyed their feedback about the course content and process. At the beginning and end of the main part, their technical competence in vaccination was assessed by two independent doctors. These doctors used a validated checklist scale (ranging from 16 to 80) and a global rating scale (ranging from 0 to 10). We used their mean scores for analysis. The quantitative data were analyzed through the Wilcoxon signed-rank test. For the qualitative data of the questionnaire, thematic analysis was conducted. RESULTS All 48 course participants participated in our study. Participants' confidence in vaccination technique (Z = -5.244, p < 0.05) and vaccination skill significantly improved (checklist rating: Z = -5.852, p < 0.05; global rating: Z = -5.868, p < 0.05). All participants rated the course as, "overall educational." Our thematic analysis identified four emerging themes: interest in medical procedures, efficacy of supervision and feedback, efficacy of "near-peer" learning, and very instructive course. CONCLUSIONS In our study, we developed a vaccine administration course for medical students, assessed their vaccination techniques and confidence in those techniques, and investigated their perceptions of the course. Students' vaccination skills and confidence improved significantly after the course, and they positively evaluated the course based on a variety of factors. Our course will be effective in educating medical students about vaccination techniques.

Abstract
Background Despite widespread availability of COVID vaccines and evidence of their efficacy, vaccine hesitancy remains prevalent. Several studies have examined the relationship between disgust sensitivity and vaccine hesitancy. Although results from studies using data collected prior to the COVID pandemic indicate that higher disgust sensitivity is related to greater vaccine hesitancy, results from studies using data collected during the COVID pandemic are equivocal. The present study examined whether perceived risk of contracting COVID moderated the relationship between disgust sensitivity and vaccine hesitancy. Methods Participants (n = 152) completed self-report measures of disgust sensitivity, perceived risk of contracting COVID, and COVID vaccine hesitancy (defined as both vaccine confidence and vaccine complacency). Results Perceived risk of contracting COVID significantly moderated the relationship between disgust sensitivity and vaccine complacency, with the association strengthened at low levels of perceived risk. Perceived risk of contracting COVID also marginally moderated the relationship between disgust sensitivity and vaccine confidence, with the association strengthened at low and average levels of perceived risk. Conclusions Results suggest that individuals with elevated disgust sensitivity who also report low levels of perceived risk of contracting COVID are more likely to express vaccine hesitancy. Implications of these findings are discussed. Supplementary Information The online version contains supplementary material available at 10.1007/s10608-023-10391-8.

Abstract
The impact of the COVID-19 infection, caused by Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), during the pandemic has been considerably more severe in pregnant women than non-pregnant women. Therefore, a review detailing the morphological alterations and physiological changes associated with COVID-19 during pregnancy and the effect that these changes have on the feto-placental unit is of high priority. This knowledge is crucial for these mothers, their babies and clinicians to ensure a healthy life post-pandemic. Hence, we review the placental morphological changes due to COVID-19 to enhance the general understanding of how pregnant mothers, their placentas and unborn children may have been affected by this pandemic. Based on current literature, we deduced that COVID-19 pregnancies were oxygen deficient, which could further result in other pregnancy-related complications like preeclampsia and IUGR. Therefore, we present an up-to-date review of the COVID-19 pathophysiological implications on the placenta, covering the function of the placenta in COVID-19, the effects of this virus on the placenta, its functions and its link to other gestational complications. Furthermore, we highlight the possible effects of COVID-19 therapeutic interventions on pregnant mothers and their unborn children. Based on the literature, we strongly suggest that consistent surveillance for the mothers and infants from COVID-19 pregnancies be prioritised in the future. Though the pandemic is now in the past, its effects are long-term, necessitating the monitoring of clinical manifestations in the near future.

Abstract
INTRODUCTION Vaccine hesitancy is complex and multifactorial and a threat to global health. Uptake of some recommended childhood immunisations in Ireland remains below World Health Organisation targets. The aim of this study was to determine factors associated with vaccine uptake in Ireland. METHODS A cross-sectional, national survey of parental attitudes towards childhood vaccination for children aged 0 to 48 months was conducted between June and August 2021 (N = 855). A descriptive analysis of questionnaire responses was conducted. Univariate and multivariable logistic regression models were constructed to identify the association of demographic parental characteristics and parental vaccine attitude scores with a delay in or lack of parental vaccine acceptance. RESULTS There was a strongly positive sentiment towards childhood vaccinations. Self-reported uptake of recommended vaccines was 96.1 % with a strong belief in the importance (94.4 %) and safety (89.2 %) of vaccines. Trust in official vaccine information sources was high; 91.5 % and 89.2 % reported trust in the vaccine information provided by healthcare professionals and the Health Service Executive (HSE) respectively. The most commonly identified reasons for missed vaccines were concerns about safety and vaccine side effects. In multivariable regression analysis, parental trust in official vaccine information sources was a significant predictor of vaccine acceptance. For every one unit increase in the median parental trust in official vaccine information score, the odds of a parent having reduced vaccine acceptance decreased significantly (aOR 0.27 95 % CI 0.16, 0.46, p < 0.001). CONCLUSION Understanding parental attitudes towards vaccination will inform the development of evidence-informed, targeted interventions to increase childhood immunisation uptake. Vaccine information for parents should focus on vaccine safety and public health action should be taken to build trust and engage communities in order to increase and sustain the uptake of childhood vaccines delivered as part of the national childhood primary immunisation programme in Ireland.

Abstract
Background Vaccination acts by boosting the capacity of a person's immune system to identify and effectively resist infection-causing bacteria and viruses, as it stimulates the immune system to respond to the vaccine's antigens. The immunological response may include local and systemic symptoms, including pain at the injection site and fever, respectively. The Sinovac vaccine is an inactivated virus vaccine made in China and is one of the most widely used vaccines in many countries; however, the side effects of the Sinovac vaccine have not been well-studied in our population. Therefore, this study assessed the prevalence of side effects experienced by participants after receiving the Sinovac vaccine. Methodology This multicenter, cross-sectional study was conducted using a non-probability sampling method. The duration of the study was six months from May 1, 2022, to October 31, 2022. A total of 800 participants who were completely vaccinated with the Sinovac vaccine were included in the study. For categorical data, frequencies and percentages were documented, while for continuous data, such as age, height, weight, and the duration of comorbidities, means and standard deviations were evaluated. Results The study findings showed that out of 800 participants, 534 (66.8%) were males and 266 (33.3%) were females, with a mean age of 41.20 ± 13.70 years. Among them, 162 (20.3%) had hypertension, and 104 (13.0%) had diabetes. Following the first dose of the Sinovac vaccine, fever was the most commonly reported side effect in 350 (43.8%) participants. Additionally, pain at the injection site in 238 (29.8%) participants, followed by swelling at the injection site in 228 (28.5%) recipients, were among other common side effects. Following the second dose of the Sinovac vaccine, fever was the most commonly reported side effect in 262 (32.8%) participants. Conclusions This study concluded that fever was the most frequent systemic side effect, whereas pain and swelling at the injection site were the most frequent local side effects following the administration of the first and second doses of the Sinovac vaccine. Both dosages of Sinovac were well-tolerated, and the majority of the adverse effects were minor and self-limiting.

Abstract
OBJECTIVE Immunization is still one of the best ways to reduce viral-related morbidity and mortality . Therefore, this study aimed to assess COVID-19 vaccine acceptance and associated factors among adult clients at public hospitals in Eastern Ethiopia. METHOD A multicentred facility-based cross-sectional study design was utilised. The systematic random sampling technique was used to select 420 study participants. The characteristics of individuals were described using descriptive statistical analysis such as frequency, median and IQR. Mean was used for health belief model components. The association was assessed using bivariate and multivariable logistic regression and described by the OR along with a 95% CI. Finally, a p-value<0.05 in the adjusted analysis was used to declare a significant association. OUTCOME MEASURE COVID-19 vaccine acceptance and associated factors. RESULT A total of 412 adult clients were interviewed, with a response rate of 98.1%. Of the total study participants, 225 (54.6%; 95% CI: 50.0% to -59.7%) were willing to accept the COVID-19 vaccine. Age≥46 (adjusted OR, AOR=3.64, 95% CI: 1.35- to 9.86), college and above level of education (AOR=2.50, 95% CI: 1.30- to 4.81), having health insurance (AOR=1.79, 95% CI: 1.11- to 2.87) and experiencing chronic disease (AOR=1.96, 95% CI: 1.02- to 3.77) were predictor variables. Also, components of the health belief model were significantly associated with COVID-19 vaccine acceptance. CONCLUSION COVID-19 vaccine acceptance among the adult population was low compared to other study. Factors associated with COVID-19 vaccine acceptance were age, college and above level of education, having a chronic disease, having health insurance, perceived susceptibility, perceived severity, perceived benefit and perceived barrier.Improving awareness about COVID-19 among all sections of the population is crucial to improving vaccine acceptability.

Alimoradi Z, Lin CY, Pakpour AH. Worldwide Estimation of Parental Acceptance of COVID-19 Vaccine for Their Children: A Systematic Review and Meta-Analysis. Vaccines (Basel) 2023; 11:vaccines11030533. [PMID: 36992117 DOI: 10.3390/vaccines11030533] [Citation(s) in RCA: 24] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 02/19/2023] [Accepted: 02/21/2023] [Indexed: 03/07/2023] Open
Abstract
Currently, the best method to well control the spread of COVID-19 without severe mental health problems is to reach herd immunity. Therefore, the vaccination rate of the COVID-19 vaccine is critical. Among the populations, children are the vulnerable ones to get vaccinated; therefore, it is important to assess parents’ and guardians’ willingness to have their children vaccinated. The present systematic review and meta-analysis synthesized evidence to estimate the parents’ acceptance rate of COVID-19 vaccination toward their children. Additionally, factors explaining the acceptance rate were investigated. Four academic databases (PubMed, Scopus, Web of Science, and ProQuest) together with Google Scholar were searched, and the references of the included publications were searched as well. Using the PECO-S framework (population, exposure, comparison, outcome, and study design), observational studies of cross-sectional, cohort, or case-control studies were included. The outcome was parents’ or guardians’ willingness to let their children be vaccinated. The studies included in the present review were restricted to English and peer-reviewed papers published between December 2019 and July 2022. A total of 98 papers across 69 different countries with 413,590 participants were included. The mean age of the parents was 39.10 (range: 18–70) years and that of their children was 8.45 (range: 0–18) years. The pooled estimated prevalence of parental acceptance to vaccinate their children with the COVID-19 vaccine was 57% (98 studies, 95% CI: 52–62%, I2: 99.92%, τ2: 0.06). Moreover, data collection time was a significant factor explaining parental willingness in the multivariable meta-regression, with a 13% decrease in parental willingness by each month increase in time, explaining 11.44% of variance. Qualitative synthesis results showed that parents’ COVID-19 vaccine knowledge, trust in theCOVID-19 vaccine, and facilitators in vaccination (e.g., low cost, good vaccine accessibility, and government incentive) were significant factors for higher willingness, while mental health problems (e.g., having worries and psychological distress) were significant factors for lower willingness. Given that the acceptance rate was relatively low (57%) and does not achieve the requirement of herd immunity (i.e., 70%), governments and healthcare authorities should try to elevate parents’ knowledge and trust in the COVID-19 vaccine, facilitate in vaccination, and reduce their mental difficulties to improve the overall vaccination rate among children.

Acceptance of COVID-19 vaccine among sub-Saharan Africans (SSA): a comparative study of residents and diasporan dwellers. BMC Public Health 2023; 23:191. [PMID: 36709269 PMCID: PMC9884132 DOI: 10.1186/s12889-023-15116-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 01/23/2023] [Indexed: 01/29/2023] Open
Abstract
BACKGROUND The COVID-19 vaccines are being rolled out across all the sub-Saharan Africa (SSA) countries, with countries setting targets for achieving full vaccination rates. The aim of this study was to compare the uptake of, resistance and hesitancy to the COVID-19 vaccine between SSA locally residents and in the diasporan dwellers. METHODS This was a cross-sectional study conducted using a web and paper-based questionnaire to obtain relevant information on COVID-19 vaccine acceptance. The survey items included questions on demography, uptake and planned acceptance or non-acceptance of the COVID-19 vaccines among SSAs. Multinomial logistic regression was used to determine probabilities of outcomes for factors associated with COVID-19 vaccination resistance and hesitancy among SSA respondents residing within and outside Africa. RESULTS Uptake of COVID-19 vaccines varied among the local (14.2%) and diasporan (25.3%) dwellers. There were more locals (68.1%) who were resistant to COVID-19 vaccine. Participants' sex [adjusted relative risk (ARR) = 0.73, 95% CI: 0.58 - 0.93], education [primary/less: ARR = 0.22, CI:0.12 - 0.40, and bachelor's degree: ARR = 0.58, CI: 0.43 - 0.77]), occupation [ARR = 0.32, CI: 0.25-0.40] and working status [ARR = 1.40, CI: 1.06-1.84] were associated with COVID-19 vaccine resistance among locals. Similar proportion of local and diasporan dwellers (~ 18% each) were hesitant to COVID-19 vaccine, and this was higher among health care workers [ARR = 0.25, CI: 0.10 - 0.62 and ARR = 0.24, CI:0.18-0.32, diaspora and locals respectively]. After adjusting for the potential confounders, local residents aged 29-38 years [ARR = 1.89, CI: 1.26-2.84] and lived in East Africa [ARR = 4.64, CI: 1.84-11.70] were more likely to report vaccine hesitancy. Knowledge of COVID vaccines was associated with hesitancy among local and diasporan dwellers, but perception was associated with vaccine resistance [ARR = 0.86,CI: 0.82 - 0.90] and hesitancy [ARR = 0.85, CI: 0.80 - 0.90], only among the local residents. CONCLUSIONS Differences exist in the factors that influence COVID-19 vaccine acceptance between local SSA residents and thediasporan dwellers. Knowledge about COVID-19 vaccines affects the uptake, resistance, and hesitancy to the COVID-19 vaccine. Information campaigns focusing on the efficacy and safety of vaccines could lead to improved acceptance of COVID-19 vaccines.

The predictive role of parental attitudes toward COVID-19 vaccines and child vulnerability: A multi-country study on the relationship between parental vaccine hesitancy and financial well-being. Front Public Health 2023; 11:1085197. [PMID: 36875362 PMCID: PMC9980903 DOI: 10.3389/fpubh.2023.1085197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 01/03/2023] [Indexed: 02/18/2023] Open
Abstract
Background and purpose Recent new mutations and increases in transmission of COVID-19 among adolescents and children highlight the importance of identifying which factors influence parental decisions regarding vaccinating their children. The current study aims to explore whether child vulnerability and parents' attitudes toward vaccines mediate the association between perceived financial well-being and vaccine hesitancy among parents. Method A predictive, cross-sectional, multi-country online questionnaire was administered with a convenience sample of 6,073 parents (Australia, 2,734; Iran, 2,447; China, 523; Turkey, 369). Participants completed the Parent Attitude About Child Vaccines (PACV), the Child Vulnerability Scale (CVS), a Financial Well-being (FWB) measure, and Parental Vaccine Hesitancy (PVH) questionnaire. Results The current study revealed that perceived financial well-being had significant and negative associations with parents' attitudes toward COVID-19 vaccines and child vulnerability among the Australian sample. Contrary to the Australian findings, results from Chinese participants indicated that financial well-being had significant and positive predictive effects on parent attitudes toward vaccines, child vulnerability, and parental vaccine hesitancy. The results of the Iranian sample revealed that parents' attitudes toward vaccines and child vulnerability significantly and negatively predicted parental vaccine hesitancy. Conclusion The current study revealed that a parents' perceived financial well-being had a significant and negative relationship with parental attitudes about vaccines and child vulnerability; however, it did not significantly predict parental vaccine hesitancy among Turkish parents as it did for parents in Australia, Iran, and China. Findings of the study have policy implications for how certain countries may tailor their vaccine-related health messages to parents with low financial wellbeing and parents with vulnerable children.

Abstract
OBJECTIVE The aim: To evaluate the acceptance rate of COVID-19 vaccine among adolescents and exploring the association factors that affect the acceptability of the vaccine. PATIENTS AND METHODS Materials and methods: The study is descriptive cross-sectional study based on online survey conducted on 541 adolescents in Iraqi middle Euphrates provinces. Survey data was collected from November 28, 2021 to April 20, 2022. RESULTS Results: The study showed that about 53% (288 adolescents out of total 541) had not been vaccinated yet and approximately 55% of the not vaccinated adolescents refused to take the vaccine. The mean reasons of this hesitancy were falsified information, insufficient information, concerned about safety and effectiveness of the vaccine. The parents whether infected with COVID-19 or vaccinated considered as strong independent factors that will increase acceptance of vaccination among the adolescents while afraid from the vaccine was considerable independent factor that decrease the acceptance rate. CONCLUSION Conclusions: High hesitancy rate toward COVID-19 vaccination among adolescents and their parents play significant role model in increasing the acceptability while concerning of the vaccine safety decreasing acceptability.

Abstract
BACKGROUND Concerns about the safety and adverse reactions of rapidly-developed vaccines against COVID-19 contributed to parents' vaccine hesitancy and this situation created an opportunity for anti-vaccine campaigners. The aim of this study was to examine the changes in parents' attitudes towards childhood vaccines during COVID-19 pandemic. METHODS In this cross-sectional study, parents of children who applied to the outpatient clinic of pediatric department of Trakya University Hospital, Edirne, Türkiye, between August 2020 and February 2021 were recruited into two study groups according to COVID-19 peak time in Türkiye. Group 1 included parents of children who applied after first peak of the COVID-19 pandemic and Group 2 included parents of children who applied after second peak. The World Health Organization 10-item Vaccine Hesitancy Scale (WHO-VHS) was applied to each group. RESULTS A total of 610 parents agreed to participate in the study. Group 1 and 2 consisted of 160 and 450 parents, respectively. While the number of parents who were hesitant about childhood vaccines was 17 (10.6%) in Group 1, it was 90 (20%) in Group 2. A statistically significant difference was found between the two groups (p = 0.008). The (WHO-VHS) mean ± SD score was found to be higher in Group 2 (23.7 ± 6.9) than Group 1 (21.3 ± 7.3) (p < 0.001). The WHO-VHS- mean ± SD scores of parents who experienced COVID-19 infection themselves or their family or acquaintances were significantly lower than those who did not (20.0 ± 6.5 vs. 24.7 ± 6.9) (p < 0.001). CONCLUSIONS The hesitant attitudes towards childhood and COVID-19 vaccines were low in parents who directly or indirectly experienced COVID-19 or were worried about the devastating effects of this disease. However, it was shown that as the COVID-19 pandemic progressed, parents' hesitations towards childhood vaccines increased.

Abstract
Objective Alarmingly, the individuals' reach and coverage to get vaccinated in developing regions during the pandemic is a massive challenge for concerned authorities. This study aimed to demonstrate how cyberchondria play a significant role in a classical health belief model. Cyberchondria may influence cognitive factors (e.g. self-efficacy), which may contribute to an increase in attitude-behavior gap. Especially in the context of a health-centric scenario, it may discourage individuals to take protective measures. Method By using the cross-sectional research design, the authors conducted a quantitative survey in Pakistan and collected 563 responses from 303 male respondents (rural = 91; urban = 212) with (Urban M:35.5, standard deviation (SD):13.4) and rural M:37.5, SD:8.4). Result The findings indicate that decision self-efficacy among males is stronger than that in females. It dominates other determinants, which can dampen the individuals' intentions to get vaccinated. For instance, the effect of conspiracies and perceived seriousness was noted nonsignificant and weak. In females, perceived seriousness was stronger determinant than in males. In addition, the negative effect of decision self-efficacy was noted in the case of females, and conspiracy and cyberchondria had a negative role. Conclusion This study highlights valuable implications for future research in infodemic, health communication and health literacy, and practical implications for regulatory bodies and public administration.

Abstract
Purpose Zika virus (ZIKV) was declared a Public Health Emergency of International Concern (PHEIC) in 2016. Concerns surrounding the effects of ZIKV persist today and several vaccine candidates are currently in various stages of development worldwide. There is limited research on ZIKV vaccine acceptability worldwide, and little research specific to Latin American countries. This research aims to identify the general beliefs and acceptance of a potential ZIKV vaccine in the undergraduate population at Escuela Superior Politécnica del Litoral (ESPOL) in Guayaquil, Ecuador. Methods Between January and November 2019, 429 undergraduate students at ESPOL responded anonymously to a ZIKV vaccine survey. Frequencies, percentages, simple correspondence analysis, and bivariate inferential analyses were conducted using Kendall's tau-b test. Tests explored associations between likelihood of receiving a ZIKV vaccine and demographic, ZIKV information seeking, ZIKV psychosocial variables, and ZIKV information source variables. Results Among the eligible participants, 241 (56.2%) were willing to receive a ZIKV vaccine if one was made commercially available. Most students were male (61.5%), age 20-25 (63.3%), and of mixed (Mestizo) race (95.3%). Results provided insight into student's knowledge on ZIKV, revealed television as the most common information source, and found most students were willing to receive a ZIKV vaccine were one to become available. Bivariate results revealed most respondents reported feeling neutral or likely to receive a ZIKV vaccine regardless of their agreeability with ZIKV information seeking behavior and psychosocial variables. Conclusions This study provides insight into ZIKV knowledge among ESPOL university students and reveals most respondents obtained ZIKV related information from television. The most common reason for not wanting to receive a hypothetical ZIKV vaccine was vaccine hesitancy. Likelihood of receiving a ZIKV vaccine was associated with several information seeking behavior and psychosocial variables. Public health campaigns should focus on comprehensive ZIKV education efforts in this population.

Abstract
The vertebrate immune system functions to eliminate invading foreign nucleic acids and foreign proteins from infectious diseases and malignant tumors. Because pathogens and cancer cells have unique amino acid sequences and motifs (e.g., microbe-associated molecular patterns, MAMPs) that are recognized as "non-self" to the host, immune enhancement is one strategy to eliminate invading cells. MAMPs contain nucleic acids specific or characteristic of the microbe and are potential candidates for immunostimulants or adjuvants. Adjuvants are included in many vaccines and are a way to boost immunity by deliberately administering them along with antigens. Although adjuvants are an important component of vaccines, it is difficult to evaluate their efficacy ex vivo and in vivo on their own (without antigens). In addition, inflammation induced by currently candidate adjuvants may cause adverse events, which is a hurdle to their approval as drugs. In addition, the lack of guidelines for evaluating the safety and efficacy of adjuvants in drug discovery research also makes regulatory approval difficult. Viral double-stranded (ds) RNA mimics have been reported as potent adjuvants, but the safety barrier remains unresolved. Here we present ARNAX, a noninflammatory nucleic acid adjuvant that selectively targets Toll-like receptor 3 (TLR3) in antigen-presenting dendritic cells (APCs) to safely induce antigen cross-presentation and subsequently induce an acquired immune response independent of inflammation. This review discusses the challenges faced in the clinical development of novel adjuvants.

Abstract
BACKGROUND Severe Acute Respiratory Syndrome (SARS COV-2) known as COVID-19 since its outbreak in 2019, more than 375 and 5.6 million were infected and dead, respectively. Its influence in all disciplines stimulated different industries to work day to night relentlessly to develop safe and effective vaccines to reduce the catastrophic effect of the disease. With the increasing number of people globally who have been vaccinated, the reports on possible adverse events have grown and gained great public attention. This study aims to determine post-COVID-19 vaccination adverse effects and associated factors among vaccinated Health care providers in the Oromia region, Ethiopia in 2021. METHODS A cross-sectional study was conducted among 912 health care workers working in government hospitals in the central Oromia region from November 20 to December 15/2021. Respondents absent from work due to different reasons were excluded during the interview. The outcome variable was COVID-19 side effects (response as Yes/No). A descriptive analysis displayed findings in the form of the frequencies and percentages, and logistic regression was employed to see the association of different variables with side effects experienced. RESULT Overall, 92.1% of the participants experienced side effects either in 1st or 2nd doses of post-COVID-19 vaccination; 84.0% and (71.5%) of participants experienced at least one side effect in the 1st and 2nd dose of the vaccines, respectively. COVID-19 infection preventive protocols like keeping distance, hand wash using soap, wearing mask and using sanitizer were decreased post vaccination. About 74.3% of the respondents were worried about the adverse effects of the COVID-19 vaccine they received. The majority (80.2%) of the respondent felt fear while receiving the vaccine and 22.5% of the respondents suspect the effectiveness of the vaccine they took. About 14.8% of the vaccinated Health workers were infected by COVID-19 post-vaccination. Engaging in moderate physical activity and feeling fear when vaccinated were the independent factors associated with reported side effects of post-COVID-19 vaccination using multiple logistic regression. Respondents who did not engage in physical activity were 7.54 fold more likely to develop post-COVID-19 vaccination side effects compared to those who involved at least moderate-intensity physical activity[AOR = 7.54, 95% CI;2.46,23.12]. The odds of experiencing side effects among the respondents who felt fear when vaccinated were 10.73 times compared not felt fear (AOR = 10.73, 95% CI; 2.47,46.64), and similarly, those who felt little fear were 4.28 times more likely to experience side effects(AOR = 4.28, 95% CI; 1.28, 14.39). CONCLUSION Significant numbers of the respondents experienced side effects post COVID-19 vaccination. It is recommended to provide pre-awareness about the side effects to reduce observed anxiety related to the vaccine. It is also important to plan monitoring and evaluation of the post-vaccine effect using standard longitudinal study designs to measure the effects directly.

Abstract
Introduction The COVID-19 pandemic has severely impacted routine immunization activities and a decline in vaccination coverage has been documented around the world. The aim of this study was to assess the impact of the direct and indirect effects of the COVID-19 pandemic on routine childhood vaccination coverage in the Province of Siracusa, Italy. Methods We compared 2020 and 2019 vaccination coverage by age group and vaccine type. Results were considered statistically significant at a two-tailed p-value ≤ 0.05. Results Our findings show that vaccination coverage rates for mandatory and recommended vaccinations decreased in 2020 compared with the previous year (range from -1.4% to -7.8%). Anti-rotavirus vaccination increased (+4.8%, as compared to 2019), while the reductions observed for polio vaccination (hexavalent) and human papillomavirus vaccination in males were not statistically significant. The reduction did not hit the population in the same manner, with the greater decreases observed for children aged > 24 months compared to the younger (-5.7% vs -2.2%) and for booster doses compared to the primary vaccinations (-6.4% vs -2.6%). Conclusions This study found that vaccination coverage of routine childhood immunisations was negatively affected during the COVID-19 pandemic in the Province of Siracusa. It is of huge importance to put in place some catch-up programs to ensure vaccinations at the earliest of individuals who missed immunization during the pandemic.

Abstract
Structural and systemic inequalities can contribute to susceptibility to COVID-19 disease and limited access to vaccines. Recognizing that Racialized and Indigenous Peoples may experience unique barriers to COVID-19 vaccination, this study explored early COVID-19 vaccine accessibility, including barriers and potential solutions to vaccine access, for these communities in Canada. We conducted semi-structured interviews about challenges to accessing COVID-19 vaccination with Racialized and Indigenous Peoples, including linguistic minorities and newcomers, in Spring 2021, just as COVID-19 vaccines were becoming more widely available in Canada. Participants were purposely selected from respondents to a Canadian national online survey. Three researchers analyzed the interviews for emergent themes using a descriptive content analysis approach in NVivo. At the time of the interview, interview participants (N = 27) intended to receive (n = 15) or had received (n = 11) at least one vaccine dose, or did not state their status (n = 1). Participants described multiple barriers to COVID-19 vaccination that they personally experienced and/or anticipated they or others could experience - including technology requirements, language barriers, lack of identification documentation, and travel challenges - as well as related solutions. These were organized into three broad categories: 1) COVID-19 disease and vaccination information, 2) vaccination booking procedures, and 3) vaccination sites. These structural and systemic barriers during the initial months of vaccine rollout substantially restricted participants' COVID-19 vaccination access, even when they were eager to get vaccinated, and should be addressed early in vaccine rollouts to facilitate optimal uptake for everyone everywhere.

COVID-19 vaccine acceptance among pregnant women attending antenatal care in public hospitals in eastern Ethiopia: A multi‐center facility‐based cross‐sectional study. PUBLIC HEALTH IN PRACTICE 2022; 4:100338. [PMID: 36381560 PMCID: PMC9642041 DOI: 10.1016/j.puhip.2022.100338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/31/2022] [Accepted: 10/31/2022] [Indexed: 11/11/2022] Open
Abstract
Objectives The Ethiopian government had planned to vaccinate the total population and started to deliver the COVID-19 vaccine but, there is limited evidence about vaccine acceptance among pregnant women. Thus, this study aimed to assess COVID-19 vaccine acceptance and associated factors among pregnant women attending an antenatal care unit clinic in Eastern Ethiopia. Study design A facility-based cross-sectional study. Methods A study was conducted from June 01 to 30/2021 among systematically selected pregnant women. Data were collected using a pre-tested structured questionnaire, which was adapted from previous studies, through a face-to-face interview. Predictors were assessed using a multivariable logistic regression model and reported using an adjusted odds ratio with 95% CI. Statistical significance was declared at p-value less than 0.05. Results In this study, data from 645 pregnant women were used in the analysis. Overall, 62.2% of pregnant women were willing to be vaccinated if the vaccine is approved by the relevant authority. Fear of side effects (62.04%), a lack of information (54.29%), and uncertainty about the vaccine's safety and efficacy (25%) were the most common reasons for refusal to take the COVID-19 vaccine. The odds of unwillingness to accept the COVID-19 vaccine among pregnant women were increased significantly among mothers who were able to read and write [AOR = 2.9, 95% CI: (1.16, 7.23)], attain 9-12 grade level [AOR = 4.2, 95% CI: (2.1, 8.5)], lack information [AOR = 2.2, 95% CI: (1.41, 3.57)], and having a history of chronic diseases [AOR = 2.52, 95% CI: (1.34, 4.7)]. Conclusion Less than two-thirds of pregnant women were willing to accept the COVID-19 vaccine. Extensive public health information dissemination aimed at women with lower educational backgrounds and a history of chronic disease could be critical.

Abstract
BACKGROUND Coronavirus disease has spread worldwide since late 2019. Vaccination is critical in controlling this pandemic. However, vaccine acceptance among pregnant women is not well-studied. Therefore, this study aimed to assess the COVID-19 vaccine acceptance and associated factors among pregnant women attending antenatal care clinics in Gondar town, Northwest Ethiopia. METHODS An institution-based cross-sectional study was conducted among pregnant women attending antenatal care clinics at Gondar town, Northwest Ethiopia, 2021. About 510 study subjects were selected using a systematic random sampling technique from August 25 to September 10/2021. Data collection was done by using an interviewer-administered, structured questionnaire. Epi-info 7.2 was used to enter data and then exported to SPSS version 25 software for analysis. Bivariable and multivariable binary logistic regression models were used to identify factors associated with the outcome variable. Variables with a p-value < 0.2 in the bivariable analysis were entered into the multivariable analysis to control for possible confounders. Statistical significance is determined using an adjusted odds ratio and 95% confidence interval (CI) at a p-value of < 0.05. RESULTS Of 510 participants, 211 (41.4%) were willing to take COVID-19 vaccines. Maternal age ≥ 35 years (AOR: 5.678, 95% CI: 1.775-18.166), having contact history with COVID-19 diagnosed people (AOR: 7.724, 95% CI: 2.183, 27.329), having a pre-existing chronic disease (AOR: 3.131, 95% CI: 1.700-5.766), good knowledge about COVID-19 vaccine (AOR: 2.391, 95% CI: 1.144, 4.998) and good attitude towards COVID-19 vaccine (AOR: 2.128, 95% CI: 1.348) were significantly associated with the outcome variable. CONCLUSIONS The willingness to take COVID-19 vaccine among pregnant mothers was low. Age, contact history with COVID-19 diagnosed people, chronic disease, knowledge, and attitude towards COVID-19 vaccine were factors associated with COVID-19 vaccine willingness. To enhance the COVID-19 vaccine acceptance, the government with different stakeholders should strengthen public education about the importance of getting COVID-19 vaccine.

Abstract
OBJECTIVES The acceptance of the COVID-19 vaccine is essential for protecting the world population and stopping the COVID-19 pandemic. This paper aimed to measure public acceptance of the COVID-19 vaccination and the factors that may play an important role in increasing the acceptance of vaccinations in future pandemics. DESIGN A cross-sectional, observational study was conducted through a survey designed using the Google Forms platform. In this study, a logistic regression analysis was used to study and detect the variables linked to the acceptance of COVID-19 vaccination. To meet inclusion criteria, participants had to be 18 years or older at the time of collecting the data, reside in Saudi Arabia at the time of the survey, agree to the consent form and be able to complete the survey in Arabic. SETTING Randomly selected residents of Saudi Arabia. NUMBER OF PARTICIPANTS 1658. RESULTS In general, the population of Saudi Arabia is supportive of the COVID-19 vaccine (72.0%) and has one of the highest acceptance rates, according to global studies. We found that men (OR 0.73; 95% CI: 0.55 to 0.97) were less likely to hesitate with regard to taking the vaccine, whereas previously infected individuals were more likely to hesitate (OR 1.77; 95% CI: 1.25 to 2.50). Those with a lower monthly income (<3000 Saudi riyal) were more likely to refuse the vaccine (OR 3.54; 95% CI: 1.81 to 6.91), while those living in cities (OR 0.62; 95% CI: 0.39 to 0.99) and the unemployed (OR 0.52; 95% CI: 0.33 to 0.83) were less likely to refuse it. Participants' history of viral infection and trust in the healthcare system were found to be important factors in the public's acceptance of the vaccine. CONCLUSION In general, acceptance of the COVID-19 vaccination is high in Saudi Arabia. Several factors have shown a method for predicting those who might reject the vaccine or hesitate to take it; thus, the healthcare system should target those residents throughout the campaign. Based on the conclusions of the current research, the acceptance of vaccinations could be increased.
