Vashist K, Yankey D, Elam-Evans LD, Mu Y, Valier MR, Pingali C, Hill HA, Santibanez TA, Singleton JA. Changes in vaccine hesitancy among parents of children aged 6 months - 17 Years, National Immunization Surveys, 2019-2022. Vaccine 2024; 42:125989. [PMID: 38806351 DOI: 10.1016/j.vaccine.2024.05.037] [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: 03/20/2024] [Revised: 05/16/2024] [Accepted: 05/16/2024] [Indexed: 05/30/2024]
Abstract
BACKGROUND Vaccine hesitancy (VH) has been a major contributor to large outbreaks of vaccine-preventable diseases globally, including in the United States. METHODS Data from the 2019-2022 National Immunization Surveys were analyzed to assess parental hesitancy toward routine vaccination of their children aged 6 months -17 years. Joinpoint regression was employed to investigate trends in VH from 2019 to 2022 nationally overall and among socio-demographic subgroups. Using logistic regression, the difference between the prevalence of VH before and after the authorization of the COVID-19 vaccine for children aged 6 months-4 years, 5-11 years, and 12-17 years was computed. Both unadjusted and adjusted estimates were reported. VH was also compared within each socio-demographic subgroup with a reference level, at two-time points- before and after the authorization of the COVID-19 vaccine for each age group. RESULTS Overall, VH remained around 19.0 % from Q2 2019 to Q3 2022. Parents of non-Hispanic Black children had the largest average quarterly decrease in VH (β = -0.55; p < 0.05 by test for trend). After the authorization of the COVID-19 vaccine for children aged 6 months to 4 years, the adjusted percentage of children having parents that reported VH decreased by 2.2 (95 % CI: -3.9, -0.6) percentage points (pp) from 21.6 % to 19.4 %. Conversely, for children aged 5-11 years, VH increased by 1.2 (95 % CI: 0.2, 2.3) pp, from 19.8 % to 21.0 %. VH among parents of non-Hispanic Black children decreased after the authorization of the COVID-19 vaccine for adolescents aged 12-17 years but remained significantly higher compared to parents of non-Hispanic White children before and after authorization of the COVID-19 vaccine for all age groups. DISCUSSION About 1 in 5 children had parents reporting VH from 2019 to 2022. Parental VH increased after the authorization of the COVID-19 vaccine for children aged 5-11 years and declined for children aged 6 months-4 years.

Abstract
BACKGROUND Some public health professionals have expressed concern that the COVID-19 pandemic has increased vaccine hesitancy about routine childhood vaccines; however, the differential prevalence of vaccine hesitancy about specific vaccines has not been measured. METHODS Data from the National Immunization Survey-Child COVID-19 Module (NIS-CCM) were analyzed to assess the proportion of children ages 6 months-17 years who have a parent with hesitancy about: COVID-19, influenza, human papillomavirus (HPV) (for children ≥ 9 years) vaccines, and "all other childhood shots." Interviews from October 2022 through April 2023 were analyzed. RESULTS The percentage of children with a vaccine-hesitant parent varied by vaccine. 55.9% of children had a parent hesitant about COVID-19 vaccine, 30.9% hesitant about influenza vaccine, 30.1% hesitant about HPV vaccine, and 12.2% had a parent hesitant about other vaccines such as measles, polio, and tetanus. CONCLUSION The study findings suggest that differential interventions and communications to parents be used to educate about COVID-19, influenza, HPV, and routine childhood vaccinations because the hesitancy levels differ widely.

Exploring the relationship between vaccine hesitancy and mothers' perspectives on COVID-19 vaccines for children ages 5-11 years during the omicron predominant period 2021-2022: a qualitative study. Front Public Health 2024; 12:1355452. [PMID: 39040866 PMCID: PMC11262113 DOI: 10.3389/fpubh.2024.1355452] [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: 12/14/2023] [Accepted: 06/11/2024] [Indexed: 07/24/2024] Open
Abstract
Background The United States Food and Drug Administration authorized COVID-19 vaccines for children ages 5-11 years in October 2021 during the Omicron predominant period. Parental vaccine hesitancy was prevalent during this time, resulting in low childhood COVID-19 vaccine uptake. Most studies exploring factors influencing parental vaccine hesitancy have focused on racial and ethnic minorities and lower socioeconomic populations; however, there is little knowledge of the drive drivers of vaccine hesitancy among White parents with higher education and socioeconomic statuses. Methods We conducted semi-structured interviews with a sample of 15 White mothers of children ages 5-11 years in Atlanta, GA, between October-December 2021. Thematic analysis was performed using NVivo 12. Results Mothers were college-educated, homeowners, and fully vaccinated against COVID-19. Key findings included decreased pediatrician's recommendations for COVID-19 vaccines, reliance on information from specialized doctors and scientists, distrust in public health authorities, high risk-perception of COVID-19 vaccines, and low risk-perception of COVID-19 disease. Factors related to vaccine acceptance were altruism and practicality. Conclusion This study adds to the sparse literature on reasons for vaccine hesitancy among White mothers of children ages 5-11 years with higher educational and socioeconomic status. Improving vaccine uptake among this group is critical for protecting the health of their children and other vulnerable populations. Tailored vaccine messaging and intervention are warranted to address their unique attitudes, beliefs, and behaviors. An enhanced understanding of the factors influencing subpopulations of parents can help vaccine policymakers and healthcare providers improve efforts to reduce vaccine hesitancy, particularly for new vaccines.

Abstract
BACKGROUND The COVID-19 pandemic has led to decreased measles vaccination rates globally, exacerbating vaccine hesitancy. This study examines the relationship between COVID-19 vaccine acceptance and childhood measles vaccination among parents in Hong Kong. METHODS A cross-sectional online survey was conducted in Hong Kong from March to September 2022. Parents were recruited via the Qualtrics panel, and a total of 588 parents were invited via email or social media account to participate in the survey. We used the adjusted Measles-containing Vaccine Hesitancy Scale for the assessment of parental vaccine hesitancy for children. A multiple linear regression analysis was conducted to examine the association between parental acceptance of the COVID-19 vaccine and their attitudes towards childhood measles vaccination. RESULTS Of the 588 participants, parents who have been vaccinated against COVID-19 exhibited significantly less measles-containing vaccine hesitancy comparing to those unvaccinated (β = -2.96, 95% confidence interval [CI]: -5.10 to -0.83, p = 0.007). Mothers exhibited more hesitancy compared to fathers (β = 1.64, 95% CI: 0.60 to 2.68, p = 0.002). Parents with a higher self-rated health (β = -2.20, 95% CI: -3.21 to -1.20, p < 0.001), or who have received advice from health professionals to offer measles, influenza, or COVID-19 vaccines for kids (β = -2.41, 95% CI: -3.49 to -1.32, p < 0.001) had lower levels of hesitancy. CONCLUSION COVID-19 vaccine status of parents was associated with reduced hesitancy towards measles vaccines for their children. Addressing vaccine hesitancy effectively requires targeted communication strategies, particularly focusing on those unvaccinated and leveraging the influence of healthcare professionals.

Abstract
Objective To describe the process of engaging community, caregiver, and youth partners in codeveloping an intervention to promote equitable uptake of the COVID-19 vaccine in non-Hispanic Black (Black) and Hispanic youth who experience higher rates of COVID-19 transmission, morbidity, and mortality but were less likely to receive the COVID-19 vaccine. Methods A team of 11 Black and Hispanic community partners was assembled to codevelop intervention strategies with our interdisciplinary research team. We used a mixed-methods crowdsourcing approach with Black and Hispanic youth (n=15) and caregivers of Black and Hispanic youth (n=20) who had not yet been vaccinated against COVID-19, recruited from primary care clinics, to elicit perspectives on the acceptability of these intervention strategies. Results We codeveloped five strategies: (1) community-tailored handouts and posters, (2) videos featuring local youth, (3) family-centered language to offer vaccines in the primary care clinic, (4) communication-skills training for primary care providers, and (5) use of community health workers to counsel families about the vaccine. The majority (56-96.9%) of youth and caregivers rated each of these strategies as acceptable, especially because they addressed common concerns and facilitated shared decision-making. Conclusions Engaging community and family partners led to the co-development of culturally- and locally-tailored strategies to promote dialogue and shared decision-making about the COVID-19 vaccine. This process can be used to codevelop interventions to address other forms of public health disparities. Policy Implications Intervention strategies that promote dialogues with trusted healthcare providers and support shared decision-making are acceptable strategies to promote COVID-19 vaccine uptake among youth from historically underserved communities. Stakeholder-engaged methods may also help in the development of interventions to address other forms of health disparities.

Abstract
BACKGROUND Vaccine hesitancy is a significant threat to global health. A key part of addressing hesitancy is to ensure that public health messaging prioritises information that is considered important to the public. This study aimed to examine how different vaccine characteristics affect public preferences for vaccines in New Zealand, what trade-offs they are willing to make between different vaccine characteristics, and how their preferences are affected by their vaccine-related conspiracy beliefs and COVID-19 vaccination status. METHODS An online discrete choice experiment (DCE) was designed to elicit individual preferences about vaccines using the 1000minds platform. Members of the general population of New Zealand aged ≥ 18 years were invited to complete the DCE. Participants were asked to indicate their preference between two options showing different combinations of vaccine characteristics. Data on sociodemographic characteristics were collected. Beliefs were measured using the vaccine conspiracy beliefs scale (VCBS) with scores ≥ 19 indicating strong vaccine-related conspiracy beliefs. The DCE was analysed using the PAPRIKA method (Potentially All Pairwise RanKings of all possible Alternatives) and preferences compared between respondents with high versus low VCBS scores and vaccinated versus unvaccinated respondents for COVID-19. RESULTS A total of 611 respondents from 15 regions completed the DCE. Mean (SD) age was 45.9 (14.7) years with most having had 2 or more doses of the coronavirus vaccine (86%). Mean (SD) VCBS score was 18.5 (12.4) indicating moderate vaccine-related conspiracy beliefs. Risk of severe adverse effects was the most highly valued vaccine characteristic, followed by vaccine effectiveness and duration of protection. Vaccine origin and route of administration were ranked least important. Respondents scoring high on the VCBS placed less value on the effectiveness of vaccines but greater value on development time and total number of doses (p < 0.001). COVID-19 unvaccinated respondents ranked development time and total number of doses more highly than those vaccinated respondents (p < 0.001). CONCLUSIONS Risk of severe adverse effects, vaccine effectiveness and duration of protection were rated by the New Zealand public as the top three most important vaccine characteristics. This information is important for informing public health messaging to promote vaccine uptake and inform vaccine decision-making.

Abstract
BACKGROUND This study examined the perceived barriers of migrants and refugees to vaccinating their children against measles and polio in Iran. METHODS First, an instrument was developed and validated through several steps. Next, 1,067 parents who had not vaccinated their children against polio and measles or had delayed receiving any dose of these two vaccines until the age of 15 were selected from 16 provinces and completed the instrument. Finally, the data were analyzed. RESULTS The results of the explanatory factor analysis showed that the perceived barriers affecting vaccination against polio and measles vaccines were categorized into five factors: low knowledge, negative attitude, communication challenges, lack of participation in vaccination programs, and problems related to migration and refugees. Additionally, the results indicated a significant difference in the mean score of perceived barriers based on participants' level of education, economic status, and nationality. CONCLUSION The identified barriers may provide a perspective for developing effective efforts in this area. Interventions should focus on parents with low education and poor economic status.

Abstract
The interrelatedness of social-structural aspects and psychological features with vaccination intention provides the context to explore personal psychological features related to vaccination. Specifically, we focused on general decision making and vaccine-related dispositions, and their contribution to the intention to vaccinate, within post-pandemic circumstances, after the imposed possibility of choosing a vaccine brand. Our study aimed to map the function (promotive, protective, risk, vulnerability) of a set of personal psychological aspects in the intention to vaccinate among people holding different social roles regarding the vaccination. We surveyed three samples of people: healthcare providers (HPs), parents, and laypeople, within the post-pandemic context. Negative vaccine attitudes lower intention to vaccinate in all regression models (all βs ranging from -0.128 to -0.983, all ps < 0.01). The main results indicate that, regardless of the sample/social role, there is a shared attitudinal core for positive vaccination intention. This core consists of [high] trust in large corporations, government, and healthcare systems, as well as perceived consensus on vaccine safety/efficacy and experience of freedom (protective factors), and [low] vaccination conspiracy beliefs, trust in social media, and choice overload (risk and vulnerability factors, respectively). There are no common promotive factors of intention to vaccinate: for parents, perceived consensus on vaccines, and trust in corporations and the healthcare system, play such roles; for HPs, the experience of freedom is obtained as a unique promotive factor. In contrast, for laypeople, no unique promotive factors were found. Our findings provide insights into the function of psychological factors of vaccination intention across different social roles, particularly healthcare providers, parents, and laypeople, and emphasize the need for tailored immunization interventions in the post-pandemic landscape.

Abstract
American physicians disproportionately suffer from burnout. Despite calls for systemic solutions, however, few studies have actually examined how 'the system' works-i.e. how structural factors intersect in real-time as a system to shape wellbeing. I borrow a systems theoretical approach, which explicitly recognizes the dynamic relationships and interdependencies between different actors and factors in healthcare, to examine how structural factors work together to shape physicians' wellbeing. Drawing on an eight-month ethnography in a pediatrics clinic, I show how respondents experienced pressures from multiple structural levels: societal (including broader social inequality and changing doctor-patient relationships); organizational (centralized decision-making, economic pressures, and unresponsive leadership); and professional (specialty cultures and unhealthy norms). I find that individual physicians effectively served as shock absorbers, routinely absorbing countless, interconnected structural demands ("shocks") and converting them into competent medical care, at significant cost to their mental health. In so doing, I intervene in sociological debates about the broader fate of the medical profession and conclude that if medicine remains resilient against threats to its dominance, it may well be at the expense of individual physicians' mental wellbeing.

Abstract
BACKGROUND Despite the unequivocal benefits of vaccination, vaccine coverage has been falling in several countries in the past few years. Studies suggest that vaccine hesitancy is an increasingly significant phenomenon affecting adherence to vaccines. More recently, during the COVID-19 pandemic, political views have emerged as an additional influencing factor for vaccine hesitancy. METHODS In this ecologic study, we used information from publicly available databases to investigate the association between political ideology, depicted by the percentage of votes for the right-wing candidate Jair Bolsonaro in the presidential elections of 2018 and 2022, and COVID-19 vaccination in Brazilian municipalities. The primary endpoint was the COVID-19 vaccination index, calculated as the number of COVID-19 vaccine doses administered up to September 2022 divided by the number of inhabitants in each municipality. The analysis was conducted using Pearson correlation coefficients and linear regression models adjusted for HDI, the percentage of male voters, the percentage of voters who were older than 50 years old, and the percentage of voters with a middle school education or less. In addition, we explored whether the effect of the percentage of Bolsonaro voters on the COVID-19 vaccination index was modified in different quartiles of HDI using an interaction term. RESULTS Five thousand five hundred sixty-three Brazilian municipalities were included in the analysis. For both the 2018 and 2022 elections, the percentage of votes for Jair Bolsonaro was significantly and inversely associated with COVID-19 vaccine uptake after adjustment for the sociodemographic characteristics of the voters (change in mean vaccination index in 2018 for each 1% increase in Bolsonaro voters -0.11, 95% confidence interval [CI] -0.13 to -0.08, p < 0.001; change in mean vaccination index in 2022 for each 1% increase in Bolsonaro voters -0.09, 95% CI -0.11 to -0.07, p < 0.001). We also found a statistically significant interaction between the primary predictor of interest and HDI scores, with a more significantly detrimental effect of the right-wing political stance in municipalities in the lower HDI quartiles (interaction p < 0.001 for the first HDI quartile; p = 0.001 for the second HDI quartile). CONCLUSION Our findings suggest that political ideologies have influenced COVID-19 vaccine hesitancy in Brazilian municipalities, affecting communities inequitably. The politicization of vaccines is a new challenge for vaccine programs. Strategies to face these challenges should include joint efforts from governments and civil society for a common public health goal.

[PMID: 37544988 PMCID: PMC10404373 DOI: 10.1186/s12879-023-08478-4] [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: 02/27/2023] [Accepted: 07/21/2023] [Indexed: 08/08/2023] Open
Abstract
BACKGROUND Vaccination is essential to protect from influenza and recently from COVID-19, yet uptake in Lebanon is suboptimal. Several factors determine uptake including knowledge, attitude and policies. We conducted a scoping review of the literature to explore the determinants of influenza and COVID-19 vaccine intent or uptake in Lebanon. METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, thirty one peer reviewed studies indexed in six databases Pub Med, EMBASE, Scopus, CINAHL, Medline, and the Cochrane Library were screened. Two students, a senior Librarian and an Associate Professor in nursing searched for eligible studies. The library search strategy followed a combination of three broad concepts (viral influenzas; vaccines; Lebanon). The search timeframe was up till December 31, 2022. Determinants of influenza and COVID-19 vaccine intent or uptake were categorized following the constructs of the Theory of Planned Behavior. RESULTS Nine studies investigated influenza vaccine intent or uptake among the public community, parents and healthcare workers. Twenty one studies investigated COVID-19 vaccine intent or uptake among the public community, older refugees, university students, patients with cancer, dentists, and social media users. One study investigated both types of vaccines. A conceptual model of the determinants of vaccine intent and uptake within the Lebanese context was developed. Various determinants included environmental factors, norms, knowledge, perceptions, attitudes, past experiences, behavioral control and hesitancy. CONCLUSIONS Research on vaccine intent and uptake in Lebanon is still in its infancy, while that of COVID-19 is on the rise. Multifaceted reasons behind the low vaccination rates were observed yet few attempts were made to target vulnerable groups. Further research studies are needed to target vulnerable groups.

Abstract
Hemorrhagic disease of the newborn, more aptly termed "Vitamin K Deficiency Bleeding (VKDB)," has long been recognized as a cause of significant morbidity and mortality in early infancy. A single intramuscular dose of vitamin K administered at birth has virtually eliminated VKDB, and this prophylactic regimen has been recommended by the American Academy of Pediatrics since 1961. Although most newborns in the United States receive vitamin K at birth, a growing number of parents are hesitant about this intervention, citing concerns about harm from the injection, preservatives contained in the medication, and clashes with personal belief systems. Ultimately, there is distrust in the medical establishment as many of these parents also opt out of newborn ophthalmic prophylaxis and importantly, childhood vaccinations, establishing a dangerous public health precedent that will lead to resurgence of vaccine-preventable diseases. Various shared decision making models and educational efforts can assist newborn health care professionals in addressing these parental concerns so that VKDB can be effectively prevented in all newborns.

Abstract
OBJECTIVES Outbreaks in vaccine-preventable diseases among children have increased, primarily among under- or unvaccinated subgroups. The influence and interaction of a child's school community on parental health care decisions, such as vaccination, has not been explored. Our study examined childhood coronavirus disease 2019 (COVID-19) vaccine hesitancy within the context of school communities. METHODS This study combines data from 4 independent research studies funded by the National Institutes of Health Rapid Acceleration of Diagnostics Underserved Populations Return to School Initiative. We examined focus group data to better understand the apprehension surrounding parental and child COVID-19 vaccination among underserved school populations. RESULTS Across all study sites, 7 main themes emerged with regard to COVID-19-related vaccination concerns for children: (1) potential side effects, (2) vaccine development, (3) misinformation (subthemes: content of vaccine and negative intent of the vaccine), (4) vaccine effectiveness, (5) timing of vaccine administration/availability for children, (6) fear of needles, and (7) mistrust. CONCLUSIONS School settings offered unique access to youth and family perspectives in underserved communities. Our studies highlighted several factors contributing to COVID-19 vaccine hesitancy in school communities, which align with existing literature on vaccine hesitancy. These concerns centered primarily on potential harm of vaccines, as well as misinformation, mistrust, and timing of vaccines. Related recommendations for increasing vaccination rates are provided. Developing specific strategies that address parent and child concerns will be critical to reducing health inequities related to COVID-19 vaccination.

Acceptance of COVID-19 vaccination among parents of children with autism and other neurodevelopmental disorders in Saudi Arabia: a cross-sectional study. BMC Public Health 2023; 23:1235. [PMID: 37365523 PMCID: PMC10294403 DOI: 10.1186/s12889-023-16127-3] [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: 09/27/2022] [Accepted: 06/15/2023] [Indexed: 06/28/2023] Open
Abstract
BACKGROUND Acceptance of COVID-19 vaccination was noticed to be less common among parents of children with autism spectrum disorder (ASD) and other neurodevelopmental disorders. This study aimed to explore the beliefs and willingness of parents of children with neurodevelopmental disorders about COVID-19 vaccine and understand how certain factors influencing the vaccine decision-making process differ between them and other parents' groups. METHODS A cross-sectional study was conducted between August to November 2021. An Arabic online survey was distributed in August 2021 to collect the study's data. 400 parents from all the major regions in Saudi Arabia participated in and shared their beliefs about the new COVID-19 vaccination for their children. RESULTS Out of 400 participants, 381 of them were eligible to answer the survey (95.2%). The total number of parents of children with neurodevelopmental disorder was 158 (41.5%), was compared to responses of parents of heathy children 223 (58.5%). 85 (53.8%) of them were ready to vaccinate their children with COVID-19 vaccine. While 36 (22.8%) were hesitant, the rest 37 (23.4%) did not want to vaccinate their children at all. Only a small number 16 (10.1%) have beliefs of vaccines as a cause of their child's neurodevelopmental disorder. A total of 79 out of 131 responses were received from both parents' groups. Fear of long-term side-effects was the most common reason reported by 41 responders out of 64 (64.06%) from parents of healthy children and 38 responders out of 67 (56.71%) from parents of diagnosed children. Another reason reported by parents of younger children in both groups was the child's age. Having a healthcare relative worker was significantly associated with the vaccine decision making (p < .001). CONCLUSION The acceptance rate of COVID-19 vaccination of parents of children with neurodevelopmental disorders was low compared to the parents of healthy children in Saudi Arabia. Authorities can benefit from this study results to offer more accessible information about the vaccine importance and safety to the targeted population.

QUALITATIVE RESEARCH IN HEALTH 2023; 3:100270. [PMID: 37073370 PMCID: PMC10101486 DOI: 10.1016/j.ssmqr.2023.100270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 02/26/2023] [Accepted: 04/08/2023] [Indexed: 04/20/2023]
Abstract
Vaccines have played an essential role in curbing case and mortality rates due to SARS-CoV-2 in the United Sates. Still, many communities display high rates of unwillingness or inability to get a COVID-19 vaccine, limiting overall vaccination efforts and contributing to viral spread. Black Americans have expressed skepticism towards vaccines because of limited access to the technology, mistrust in its safety and efficacy, and a lack of confidence in the healthcare authorities that distribute it. This article investigates how Black residents of Wards 7 and 8 in Washington, D.C. thought about COVID-19 vaccination and why or why not they decided to vaccinate. These Wards' vaccination rates were markedly lower than those from Wards 1-6, which have substantially higher populations of White residents, affluence, access, and resources. This study involved 31 interviews with Ward 7 and 8 residents recruited through snowball sampling. We found that residents navigated the dual perceived risks of coronavirus infection and vaccination through three key frames: their relationship to their place or location, their desires to maintain autonomy over their health, and their abilities to access COVID-19 vaccines. This case study advances knowledge of vaccine utilization among marginalized communities, and how this phenomenon varies depending on local social, cultural, and political dynamics. Moreover, this research has implications for vaccine rollout efforts and the D.C. health system, as it reveals gaps in confidence and care that undermine health outcomes for Black residents.

Int J Gen Med 2023; 16:1927-1941. [PMID: 37228742 PMCID: PMC10204751 DOI: 10.2147/ijgm.s412380] [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: 04/10/2023] [Accepted: 05/12/2023] [Indexed: 05/27/2023] Open
Abstract
Background Trachoma is an eye disease caused by bacteria called Chlamydia trachomatis. This infection causes papillary and/or follicular inflammation of the tarsal conjunctiva referred to as active trachoma. Active trachoma prevalence among 1 to 9 years old children is 27.2% in Fogera district (study area). Many people still require the implementation of the face cleanliness components of the SAFE strategy. Even if face cleanness is an important component to prevent trachoma, there is limited research done on this area. Therefore, the purpose of this study is to assess behavioral responses to face cleanliness messages to prevent trachoma among mothers having children aged 1 to 9 years old. Methods A community-based cross-sectional study was conducted with the guidance of an extended parallel process model in Fogera District from December 01 to December 30, 2022. A multi-stage sampling technique was used to select 611 study participants. Interviewer administered questionnaire was used to collect the data. Bivariable and multivariable logistic regression analysis was done to identify predictors of behavioral responses using SPSS V.23 significant variables were declared by AOR at a 95% confidence interval and a p-value <0.05. Result Among the total participants, 292 (47.8%) were in danger control. Residence [AOR = 2.91; 95% CI: (1.44-3.86)], marital status [AOR = 0.79; 95% CI: (0.667-0.939)], level of education [AOR = 2.74; 95% CI: (1.546-3.65)], family size [AOR = 0.57; 95% CI: (0.453-0.867)], round trip to collect water [AOR = 0.79; 95% CI: (0.423-0.878)], having information about face washing [AOR = 3.79; 95% CI: (2.661-5.952)], Source of an information health facility [AOR = 2.76; 95% CI: (1.645-4.965)], school [AOR = 3.68; 95% CI: (1.648-7.530)], health extension workers [AOR = 3.96; 95% CI: (2.928-6.752)], Women development army [AOR = 2.809; 95% CI: (1.681-4.962)], knowledge [AOR = 2.065; 95% CI: (1.325-4.427)] self-esteem [AOR = 1.013; 95% CI: (1.001-1.025)], self-control [AOR = 1.132; 95%CI: (1.04-1.24)], and future orientation [AOR = 2.16; 95% CI: (1.345-4.524)] were found to be statistically significant predictors of behavioral response. Conclusion Less than half of the participants were in the danger control response. Residence, marital status, level of education, family size, face-washing information, source of information, knowledge, self-esteem, self-control, and future orientation were independent predictors of face cleanliness. Strategies of face cleanliness messages should give high attention to perceived efficacy with consideration of perceived threat.

Abstract
Health perceptions and health-related behaviors can change at the population level as cultures evolve. In the last decade, despite the proven efficacy of vaccines, the developed world has seen a resurgence of vaccine-preventable diseases (VPDs) such as measles, pertussis, and polio. Vaccine hesitancy, an individual attitude influenced by historical, political, and socio-cultural forces, is believed to be a primary factor responsible for decreasing vaccine coverage, thereby increasing the risk and occurrence of VPD outbreaks. Behavior change models have been increasingly employed to understand disease dynamics and intervention effectiveness. However, since health behaviors are culturally influenced, it is valuable to examine them within a cultural evolution context. Here, using a mathematical modeling framework, we explore the effects of cultural evolution on vaccine hesitancy and vaccination behavior. With this model, we shed light on facets of cultural evolution (vertical transmission, community influences, homophily, etc.) that promote the spread of vaccine hesitancy, ultimately affecting levels of vaccination coverage and VPD outbreak risk in a population. In addition, we present our model as a generalizable framework for exploring cultural evolution when humans' beliefs influence, but do not strictly dictate, their behaviors. This model offers a means of exploring how parents' potentially conflicting beliefs and cultural traits could affect their children's health and fitness. We show that vaccine confidence and vaccine-conferred benefits can both be driving forces of vaccine coverage. We also demonstrate that an assortative preference among vaccine-hesitant individuals can lead to increased vaccine hesitancy and lower vaccine coverage.

Abstract
BACKGROUND Human papillomavirus (HPV) is responsible for most cervical cancer cases globally, with women living with HIV having a higher risk of persistent HPV infection and HPV-associated disease. The HPV vaccine is a promising tool to reduce cervical cancer rates, but its uptake among women living with HIV in Nigeria is unknown. METHODS A facility-based, cross-sectional survey was conducted with 1371 women living with HIV to assess their knowledge of HPV, cervical cancer, and the HPV vaccine as well as their willingness to pay for the vaccine at the HIV treatment clinic at the Nigerian Institute of Medical Research, Lagos. To identify factors associated with the willingness to pay for the HPV vaccine, multivariable logistic regression models were developed. RESULTS This study found that 79.1% of participants had not heard of the vaccine, and only 29.0% knew its efficacy in preventing cervical cancer. In addition, 68.3% of participants were unwilling to pay for the vaccine, and the average amount they were willing to pay was low. Knowledge of HPV, the HPV vaccine, and cervical cancer and income were factors associated with the willingness to pay for the vaccine. Health workers were the primary source of information. CONCLUSIONS This study highlights the lack of knowledge and low willingness to pay for the HPV vaccine among women living with HIV in Nigeria and emphasizes the importance of improving education and awareness. Factors associated with the willingness to pay, such as income and knowledge, were identified. Practical strategies, such as community outreach and school-based education programs, could be developed to increase vaccine uptake. Further research is needed to explore additional factors influencing the willingness to pay.

Why Parents Say No to Having Their Children Vaccinated against Measles: A Systematic Review of the Social Determinants of Parental Perceptions on MMR Vaccine Hesitancy. Vaccines (Basel) 2023; 11:vaccines11050926. [PMID: 37243030 DOI: 10.3390/vaccines11050926] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 04/20/2023] [Accepted: 04/24/2023] [Indexed: 05/28/2023] Open
Abstract
Ongoing outbreaks of measles threaten its elimination status in the United States. Its resurgence points to lower parental vaccine confidence and local pockets of unvaccinated and undervaccinated individuals. The geographic clustering of hesitancy to MMR indicates the presence of social drivers that shape parental perceptions and decisions on immunization. Through a qualitative systematic review of published literature (n = 115 articles; 7 databases), we determined major themes regarding parental reasons for MMR vaccine hesitancy, social context of MMR vaccine hesitancy, and trustworthy vaccine information sources. Fear of autism was the most cited reason for MMR hesitancy. The social drivers of vaccine hesitancy included primary care/healthcare, education, economy, and government/policy factors. Social factors, such as income and education, exerted a bidirectional influence, which facilitated or hindered vaccine compliance depending on how the social determinant was experienced. Fear of autism was the most cited reason for MMR hesitancy. Vaccine hesitancy to MMR and other childhood vaccines clustered in middle- to high-income areas among mothers with a college-level education or higher who preferred internet/social media narratives over physician-based vaccine information. They had low parental trust, low perceived disease susceptibility, and were skeptical of vaccine safety and benefits. Combating MMR vaccine misinformation and hesitancy requires intersectoral and multifaceted approaches at various socioecological levels to address the social drivers of vaccine behavior.

Abstract
There are several factors that influence childhood vaccine uptake. Pediatric clinicians play a particularly influential role in parent vaccine decision-making. It is critical therefore that pediatric clinicians have a "communication toolbox"--a set of effective, evidence-based communication strategies to facilitate uptake of childhood vaccines--that they can use in conversations with parents about vaccines. In this article, recent advances in our understanding of what constitutes effective clinician vaccine communication with parents are discussed.

Abstract
Widespread uptake of COVID-19 vaccination is vital to curtailing the pandemic, yet rates remain suboptimal in the U.S. Vaccine mandates have previously been successful, but are controversial. An April 2021 survey of a nationally representative sample (N = 1208) examined vaccine uptake, attitudes, and sociodemographic characteristics. Sixty-seven percent were vaccine acceptors, 14% wait-and-see, and 19% non-acceptors. Compared to wait-and-see and non-acceptors, acceptors were more likely to have a household member over age 65, have received a flu shot, have positive COVID-19 vaccine attitudes, and view COVID-19 vaccination as beneficial. Mandate support was higher among respondents who were vaccine acceptors, had positive views about COVID-19 vaccines, believed in COVID-19 preventive strategies, perceived COVID-19 as severe, were liberal, resided in the Northeast, were non-White, and had incomes < $75,000. Public health campaigns should target attitudes that appear to drive hesitancy and prepare for varying mandate support based on demographics, COVID-19 vaccine attitudes, and the scope of the mandate.

Maternal vaccination against pertussis as part of the national immunization program: a qualitative evaluation among obstetric care providers one year after the implementation in December 2019. BMC Health Serv Res 2023; 23:311. [PMID: 36998072 PMCID: PMC10062680 DOI: 10.1186/s12913-023-09274-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 03/10/2023] [Indexed: 04/01/2023] Open
Abstract
BACKGROUND Immunization of pregnant women with a tetanus-diphtheria-and-acellular-pertussis (Tdap) vaccine is an effective and safe way to protect infants from pertussis before their primary vaccinations. Vaccine uptake among pregnant women is influenced by their care providers' attitudes toward maternal vaccination. This qualitative study aimed to evaluate the implementation of the maternal Tdap vaccination under the National Immunization Program of the Netherlands from the perspective of obstetric care providers. METHODS In this qualitative and explorative study, we conducted in-depth interviews by telephone with obstetric care providers who were selected from a pool of respondents (convenience sampling) to a questionnaire in a previous study. The interviews were based on a semi-structured interview guide that covered three aspects of the implementation strategy: providers' overall experience with the implementation of maternal Tdap vaccination in the Netherlands; implementation logistics and counseling, and pregnant women referrals to municipal Youth Healthcare Centers. The interviews were recorded, pseudonymized and transcribed verbatim. Transcripts were analyzed according to the Thematic Analysis approach by two researchers independently in two phases of iterative coding, categorizing, reviewing and redefining until ultimately, emergent themes regarding maternal Tdap vaccination implementation were identified. RESULTS Interviews with 11 midwives and 5 OB-GYN physicians yielded 5 major themes regarding the Tdap vaccination implementation strategy: challenges throughout the implementation process, views on maternal Tdap vaccination, general versus tailored counseling, provider responsibilities in vaccine promotion, and impact of materials for information delivery. Participants indicated that to improve provider attitudes toward Tdap vaccination, its implementation requires clear and transparent information about what is entailed, i.e., what is expected from obstetric care providers, how they can obtain information, and when their actions must be initiated. Participants demanded involvement throughout the implementation planning process. They preferred tailored communication with pregnant women over a generalized approach. CONCLUSION This study emphasized the importance of involving all relevant healthcare professionals in planning the implementation of maternal Tdap vaccination. Possible barriers perceived by these professionals should be taken into account in order to improve their attitudes toward vaccination, thus to increase uptake among pregnant women.

Abstract
Background Since July 2021, some countries and regions have initiated the vaccination of minors against coronavirus disease (COVID-19), and parental COVID-19 vaccine hesitancy will affect the vaccination of minors. We aimed to identify the level of parental hesitancy to vaccinate their children against COVID-19 in Taiwan and the factors associated with vaccine hesitancy. Methods We conducted a population-based, self-administered online questionnaire in Taiwan to assess parental hesitancy and the factors influencing their children’s vaccination against COVID-19. Results Among 384 respondents, 64.1% were hesitant to have their children vaccinated against COVID-19. Mothers were more likely to hesitate to vaccinate their teens than their fathers (67.5% vs. 50%, P < 0.005). Multiple regression results showed that parents who were hesitant to vaccinate themselves (OR = 3.81, 95% CI:2.07–7.02) and those who scored lower on their perception of their children’s vaccination (OR = 9.73, 95% CI:5.62–16.84) were more hesitant to vaccinate their children with COVID-19 vaccine. Conclusions According to the study findings, 64.1% of Taiwanese parents were hesitant to vaccinate their children against COVID-19. Parents who were hesitant to receive the COVID-19 vaccine for themselves and had negative views of the vaccine for their children were more likely to be hesitant to vaccinate their children. An in-depth discussion of the factors affecting vaccine hesitancy and targeted health education is conducive to promoting vaccination in children with COVID-19.

When should a longer needle be used for intramuscular injection in obese patients? A combined analysis of New Zealand data. Vaccine 2023; 41:2690-2695. [PMID: 36935287 DOI: 10.1016/j.vaccine.2023.03.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 02/14/2023] [Accepted: 03/08/2023] [Indexed: 03/19/2023]
Abstract
AIM To estimate thresholds for Body Mass Index (BMI) and arm circumference above which a longer needle is needed to ensure intramuscular (IM) delivery of a vaccine in the deltoid muscle at the site recommended by New Zealand (NZ) immunization guidelines. METHODS A combined analysis of two studies, including 442 adults, with measurements of arm circumference, BMI and skin to deltoid muscle distance (SDMD) at the NZ immunization guideline-recommended IM injection site. Receiver Operator Characteristic curves identified arm circumference and BMI cut-points that gave 100% sensitivity for SDMD thresholds. These thresholds were: SDMD of 20 mm, accounting for a minimal penetration of 5 mm into muscle with the standard needle; and 25 mm, which is the length of a standard needle for IM injection, representing the depth this can reach. RESULTS Cut-point values for arm circumference, at which a longer needle would be required, were higher for males than females: 35 cm versus 30 cm for the 20 mm cut-point, and 40 cm versus 36.7 cm for the 25 mm cut-point respectively. The BMI cut-points were also higher for male than females: 24.6 kg/m2 versus 23.7 kg/m2 for the 20 mm cut-point, and 38.2 kg/m2 vs 31.6 kg/m2 for the 25 mm cut-point respectively. CONCLUSION Arm circumference and BMI cut-points provide practical measures from which to choose a needle length that increases the chance of successful IM vaccination. Based on our data, an arm circumference of 35 cm for men and 30 cm for women should prompt selection of a longer needle to ensure intramuscular injection at the deltoid site. Thresholds for the different skin to deltoid sites proposed internationally should be determined to enable successful IM vaccination in clinical practice beyond NZ.

Abstract
RATIONALE Despite its importance to counter the COVID-19 pandemic, vaccination has raised hesitation in large segments of the population. This hesitation makes it important to understand the mechanisms underlying vaccine acceptance. To this end, the study adopts the Semiotic Cultural Psychology Theory, holding that social behaviors - and therefore, vaccination acceptance - depend on the cultural meanings in terms of which people interpret the social world. OBJECTIVE The study aims at estimating the impact a) of the way people interpret the socio-institutional context of the pandemic and b) of the underlying cultural worldviews on vaccine acceptance. More particularly, the study tested the three following hypotheses. a) The meanings grounding the interpretation of the socio-institutional framework - that is, trust in institutions and political values - are an antecedent of vaccination acceptance. b) The impact of these meanings is moderated by the cultural worldviews (operationalized as symbolic universes). And c), the magnitude of the symbolic universes' moderator effect depends on the uncertainty to which the respondent is exposed. The exposure to uncertainty was estimated in terms of socioeconomic status - the lower the status, the high the exposure to uncertainty. METHODS An Italian representative sample (N = 3020) completed a questionnaire, measuring vaccination acceptance, the meanings attributed to the socio-institutional context - that is, political values and trust in institutions - and symbolic universes. RESULTS The findings were consistent with the hypotheses. a) Structural equation modelling proved that vaccine acceptance was predicted by trust in institutions. b) Multigroup analysis revealed that symbolic universes moderated the correlation between trust in institutions and vaccine acceptance. And c), the moderation effect of symbolic universes proved to occur only in the segment of lower socio-economic status (i.e., the group exposed to higher uncertainty). CONCLUSIONS Vaccination acceptance is not only a medical issue; it is also dependent upon the rationalization of the socio-institutional context. Implications for the promotion of vaccination acceptance are discussed.

Abstract
BACKGROUND A decline in routine vaccination was reported by some countries early in the COVID-19 pandemic. In the context of the pandemic, determinants of routine childhood vaccination may have changed. Changes over time in parents' perceptions of routine vaccines and intentions for their children during the pandemic have not been fully explored. Understanding changes provides opportunities to promote routine childhood vaccines and address factors that may compromise parents' acceptance. METHODS We conducted longitudinal analysis of two sequential national surveys during the pandemic (Dec 2020 and Oct/Nov 2021) to assess changes over time in Canadian parents' perceptions of routine childhood vaccines, intentions to vaccinate, access for their children ≤ 17 years, and differences among sociodemographic characteristics. McNemar-Bowker tests were used to determine changes in parents' responses collected at two time points. RESULTS Of the 650 parents in the sample, 25.1% with a child ≤ 6 years and 20.5% with a child 7-17 years perceived that routine childhood vaccines were more important because of the pandemic. Between the two time points, parents' confidence in the safety (72.8% to 80.2%, p <.001) and effectiveness (81.7% to 85.2%, p =.007) of routine vaccines increased, parents were more engaged in vaccine decision-making (73.4% to 79.8%, p =.006), and everyday stress preventing vaccination decreased (78.8% to 68.5%, p <.001). Acceptance of routine vaccines increased (82.9% to 86.5%, p =.021), but more parents were undecided about influenza vaccination (12.6% to 20.3%, p =.002). Compared to parents with 1 child, those with 2 children reported increased vaccination acceptance (82.6% to 87.4%, p =.024). INTERPRETATION Under the spotlight of COVID-19, parents' confidence in routine vaccines, engagement in decision-making, and vaccination acceptance increased. Vaccination providers should support parents' decision-making as they navigate routine childhood vaccine uncertainties. Differences in parents' acceptance of routine and influenza vaccines for their children highlight the need for targeted communication strategies for specific vaccines.

Abstract
A growing body of literature on vaccine hesitancy considers context and the intersecting factors affecting vaccine uptake. This study attempts to add focus to the conversation of vaccines in Ukraine by exploring how vaccines are perceived and how local stakeholders envision solutions to the problems surrounding vaccine uptake. Twenty-five in-depth interviews were carried out among parents of children under 6 years of age as well as health practitioners and other experts in Ukraine. Results were presented to stakeholders during a dialogue session to discuss the implications for policy recommendations. The Roma parents interviewed faced structural barriers to vaccine access, while other groups received vaccine information from others in their communities, such as family members or religious organisations. Mistrust of the health system and lack of access to reliable information preceded many doubts parents expressed surrounding vaccines. Stakeholders agreed that better, more targeted communication strategies are needed, as well as increased engagement with and training of medical practitioners. Qualitative methods allowed for a deeper, more nuanced understanding of the factors contributing to low vaccine uptake, of which vaccine hesitancy is only one part. The vulnerability-informed approach used may have broader applications for community engagement and responding to infectious diseases and crises.

Abstract
INTRODUCTION/OBJECTIVES Annually, HPV infections result in $775 million in direct medical costs and approximately 46 000 new cases of HPV-associated cancers. Safe and highly effective vaccines have been available to prevent HPV for children/adolescents since 2006. Vaccination rates remain low, especially in rural areas. Parental attitudes and beliefs affect HPV vaccination rates. METHODS We developed, tested, and administered a survey that asked how parents and healthcare providers interacted about the HPV vaccine following a healthcare visit with an age-eligible child, as part of a multicomponent randomized controlled trial designed to improve HPV vaccination rates in rural Oregon. The 21-item survey assessed parents' information-seeking behavior, knowledge about HPV cancer risk reduction, the HPV vaccine series, and their vaccine confidence. RESULTS Forty-three participants (59.7%) were in the intervention group; 29 (40.3%) were controls. Over 90% of healthcare visits were illness, injury, sports physical, or well-child visits (n = 67 or 93.1%), and 6.9% of visits were vaccine-specific. No statistically significant differences were found between study groups for healthcare visits. Over half the parents reported having discussions about HPV and the HPV vaccine (54.5%) with their care providers, 31.3% had recently learned about HPV, HPV risks, and the HPV vaccine prior to the visit, 83.1% were knowledgeable about cancers associated with HPV, and 79.2% were considering vaccinating their child(ren), which did not differ between study groups. CONCLUSIONS Knowledge about HPV-related cancers and consideration for vaccinating children was higher than expected, but not associated with the intervention tested.

Abstract
Introduction Vaccine hesitancy may increase infectious disease burden and impede disease control efforts, while few studies have measured such a phenomenon with a standardized tool in China. This study aimed to test the validation of the Vaccine Hesitancy Scale (VHS) developed by the WHO SAGE Working Group among caregivers and examine demographic characteristics associated with caregiver hesitancy in six provinces of China. Methods Using a multistage sampling design, this study was conducted in 36 immunization clinics in six provinces from December 2019 to August 2020. Caregivers of children aged 0-3 years were included. The VHS was used to assess vaccine hesitancy. The construct validity and internal consistency of the scale were assessed. Associations between caregivers' characteristics and vaccine hesitancy were examined by simple and multiple linear regression models. Results Of the 3,359 participants included, a two-factor structure within the scale was identified, consisting of "lack of confidence" (1.89 ± 0.53) and "risks" (3.20 ± 0.75). Caregivers engaged in medical work expressed more confidence and were less concerned about risks compared to those of non-medical staff (p < 0.05). Participants with higher income levels were more confident (p < 0.05), while those surveyed after the COVID-19 pandemic, who were mothers, who had an older child, or who were raising a second or above birth child, had less concern about risks (p < 0.05). Discussion We found that the VHS had acceptable reliability and construct validity and caregivers' hesitancy was driven more by concerns about risks than by the lack of confidence. Countering these concerns will be particularly important among non-medical staff, lower income, child's fathers, having a younger child, or raising first-birth child groups.

[PMID: 36923043 PMCID: PMC10010145 DOI: 10.3389/fpubh.2023.1078009] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 01/30/2023] [Indexed: 02/17/2023] Open
Abstract
Background Vaccination is the most effective method to prevent the spread of infectious diseases. Nevertheless, vaccine hesitancy has been an issue. Parental hesitancy toward vaccines is a major part of the problem. COVID-19 vaccine acceptance is no different, it poses another challenge in facing the pandemic. In Low- and Middle-Income Countries (L&MICs) several studies measured parents' acceptance to vaccinate their children against COVID-19 and resulted in different acceptance proportions. Aims The paper aims at obtaining a precise estimate of the overall proportion of L&MICs' parents accepting to vaccinate their children against COVID-19 and identifying the main determinant of their decisions. Methods This meta-analysis follows the PRISMA 2020 statement on updated guidelines and the checklist for reporting systematic reviews. Studies published between December till February 2022 were assessed for inclusion. The final effect size (i.e., the proportion of parents in L&MICs accepting to vaccinate their children against COVID-19) was measured using the Arcsine proportions method. Analysis was done using R program. Results The proportion of parents in L&MICs accepting to vaccinate their children against COVID-19 is 49%. The major reason for their acceptance is their belief that COVID-19 vaccine is fundamental to the fight against the pandemic while the most common factor for parents' hesitancy to vaccinate their children against COVID-19 is their concerns about vaccine efficacy, safety, and possible side effects. Conclusion The proportion of parents in L&MICs accepting to vaccinate their children against COVID-19 is lower than the global level. To increase parental acceptance, responsible authorities should concentrate on increasing their population's trust in the government and in vaccine manufacturers. As well as concentrating on increasing acceptance of the vaccine idea in general.

Abstract
The number of confirmed cases of COVID-19 globally is well over 400 million, however, the number of cases is showing a downward trend especially in developed countries largely as a result of effective vaccination against COVID-19. In developing countries, vaccination coverage is still very low as a result of vaccine hesitancy, which could be attributed to misconceptions about COVID-19 itself and its newly developed vaccines. This study assessed COVID-19 vaccine acceptance and perception amongst the adult population in Sokoto state, Nigeria. A cross-sectional study was conducted in Sokoto state among 854 respondents selected via a multi-stage sampling technique. Data was collected electronically using a set of structured questionnaire and analysis was done using IBM SPSS version 25. Respondents' perception was assessed using a 5-point Likert scale ranging from strongly disagree (1) to strongly agree (5). Respondents having a score of 3 and below were graded as having poor perception and those having scores above 3 were graded as having good perception. Respondents' ages ranged from 17 to 76 years, with a mean of 34.8±12.07; more than half [474(53.7%)] of the respondents were males, 667(75.5%) were married and 539(61.0%) had formal education. The majority [839(95.0%)] of the respondents had a good perception of COVID -19 vaccine; 49.9% agreed enough research would be required on the safety of the vaccine. The majority, (72.4%) expressed their willingness to accept the COVID- 19 vaccine (male 38.4% vs. female 34.0%); 410(47.4%) said they can spend more than one hour to get the vaccine. Significant predictors of willingness to accept COVID 19 vaccine include age (p = 0.006; aOR = 0.223; 95% CI = 0.077-0.645), education (p<0.001; aOR = 1.720; 95% CI = 1.274-2.321) and perception of COVID 19 vaccine (p<0.001; aOR = 0.020; 95% CI = 0.009-0.044). The majority of the respondents had a good perception of COVID- 19 vaccine and more than two-thirds were willing to be vaccinated with the vaccine. Government should make the vaccine available for vaccination since a significant proportion of the respondents expressed their willingness to accept the vaccine.

Abstract
Vaccine hesitancy (VH) is considered a top-10 global health threat. The concept of VH has been described and applied inconsistently. This systematic review aims to clarify VH by analysing how it is operationalized. We searched PubMed, Embase and PsycINFO databases on 14 January 2022. We selected 422 studies containing operationalizations of VH for inclusion. One limitation is that studies of lower quality were not excluded. Our qualitative analysis reveals that VH is conceptualized as involving (1) cognitions or affect, (2) behaviour and (3) decision making. A wide variety of methods have been used to measure VH. Our findings indicate the varied and confusing use of the term VH, leading to an impracticable concept. We propose that VH should be defined as a state of indecisiveness regarding a vaccination decision.

Abstract
The effectiveness of motivational interviewing (MI) for reducing vaccine hesitancy (VH) has been demonstrated in Quebec. We conducted a study to evaluate the acquisition of MI skills after MI training via videoconferencing for interns training as general practitioners (GPs) in southeastern France. A vaccination-specific MI training workshop was offered to interns in 2021, consisting of two separate Zoom videoconference sessions. Participants completed the Motivational Interviewing Skills in Immunization questionnaire before and after the training to measure skills acquisition. We used pairwise exact Wilcoxon-Pratt signed rank tests for the analysis. Among 45 GP interns enrolled in the first MI session, 34 (75.6%) attended both sessions and completed the questionnaire at 3 different time points. After the first session, MI knowledge scores improved significantly (+21.1 ± 21.6; P < .0001), as did application of MI skills (+36.8 ± 36.7; P < .0001), and MI practice confidence (+21.2 ± 11.1; P < .0001). The second MI session maintained the skills developed after the first session without further improvement. Participant satisfaction was high. This is the first study in France assessing the impact of a vaccination-specific MI training for GP interns. It shows a substantial improvement in knowledge, application of MI skills, and self-confidence in the practice of MI. GP interns were highly satisfied with the training despite the videoconference format. These promising results will allow the integration of MI training in GP medical curricula in order to prepare future GPs for communication in the field of vaccination.

Abstract
Despite the benefits of immunization, differences in attitudes persist toward vaccines. We captured individuals’ perceptions of vaccines and vaccination across the United States (US) to inform vaccine-related policy development. A survey was completed by 5000 respondents from 10 states. Respondents were screened for inclusion, which included individuals ≥ 18 years of age that had received a vaccine or were unvaccinated but indicated a favorable or neutral attitude towards vaccinations. Participants were excluded if they indicated they did not support the idea of vaccinations. Questions explored perceptions of vaccines for all age groups. Among unvaccinated individuals, the most common concerns were about safety (38%). Most respondents (95%) highlighted the importance of state immunization programs for disease prevention. Access to health and immunization records and immunization information systems were important to 96% and 88% of respondents, respectively, for future health planning. Doctors and healthcare professionals (HCPs) were considered trusted sources for vaccine information (95%). Overall, respondents recognized the importance of vaccination, but documented concerns among the unvaccinated indicated a need for greater promotion regarding vaccine safety. Doctors and HCPs, as trusted information sources, should continue to and increasingly advocate for the importance of immunization to increase vaccine uptake.

Abstract
Understanding the role of vaccine hesitancy in undervaccination or nonvaccination of childhood vaccines is important for increasing vaccine confidence and uptake. We used data from April to June interviews in the 2018 and 2019 National Immunization Survey-Flu (n = 78,725, United States), a nationally representative cross-sectional household cellular telephone survey. We determined the adjusted population attributable fraction (PAF) for each recommended childhood vaccine to assess the contribution of vaccine hesitancy to the observed nonvaccination level. Hesitancy is defined as being somewhat or very hesitant toward childhood vaccines. Furthermore, we assessed the PAF of nonvaccination for influenza according to sociodemographic characteristics, Department of Health and Human Services region, and state. The proportion of nonvaccination attributed to parental vaccine hesitancy was lowest for hepatitis B birth dose vaccine (6.5%) and highest for ≥3-dose diphtheria and tetanus toxoids and acellular pertussis vaccine (31.3%). The PAF of influenza nonvaccination was highest for non-Hispanic Black populations (15.4%), households with high educational (17.7%) and income (16.5%) levels, and urban areas (16.1%). Among states, PAF ranged from 25.4% (New Hampshire) to 7.5% (Louisiana). Implementing strategies to increase vaccination confidence and uptake are important, particularly during the coronavirus disease 2019 pandemic.

Abstract
Understanding what lies behind actual COVID-19 vaccine hesitancy is fundamental to help policy makers increase vaccination rates and reach herd immunity. We use June 2021 data from the COME-HERE survey to explore the predictors of actual vaccine hesitancy in France, Germany, Italy, Luxembourg, Spain and Sweden. We estimate a linear-probability model with a rich set of covariates and address issues of common-method variance. 13% of our sample say they do not plan to be vaccinated. Post-Secondary education, home-ownership, having an underlying health condition, and one standard-deviation higher age or income are all associated with lower vaccine hesitancy of 2-4.5% points. Conservative-leaning political attitudes and a one standard-deviation lower degree of confidence in the government increase this probability by 3 and 6% points respectively. Vaccine hesitancy in Spain and Sweden is significantly lower than in the other countries.

Abstract
OBJECTIVE The U.S. Advisory Committee on Immunization Practices (ACIP) recommends that infants born weighing less than 2,000 g receive the hepatitis B (HepB) vaccine at hospital discharge or 30 days of age. This study aimed to assess timely HepB vaccination among low birth weight infants. We hypothesized that many of these vulnerable infants would fail to receive their HepB birth dose on time. STUDY DESIGN This retrospective cohort study included Washington State infants born weighing less than 2,000 g at an academic medical center between 2008 and 2013. Data were abstracted from electronic health records and linked to vaccine data from the Washington State Immunization Information System. Multivariable logistic regression was used to examine the associations between sociodemographic, clinical, and visit characteristics and HepB vaccination by birth hospitalization discharge or 30 days of age. RESULTS Among 976 study infants, 58.4% received their HepB vaccine by birth hospitalization discharge or 30 days of age. Infants had higher odds of timely HepB vaccination if they were Hispanic (adjusted odds ratio [AOR] = 1.80, 95% confidence interval [CI]: 1.10-2.95) or non-Hispanic black (AOR = 2.28, 95% CI: 1.36-3.80) versus non-Hispanic white or if they were hospitalized 14 days or longer versus less than 14 days (AOR = 2.43, 95% CI: 1.66-3.54). Infants had lower odds of timely HepB vaccination if they were born before 34 weeks versus on or after 34 weeks of gestational age (AOR = 0.41, 95% CI: 0.27-0.63) or if they had an estimated household income less than $50,845 versus 50,845 or greater (AOR = 0.64, 95% CI: 0.48-0.86). CONCLUSION Many infants born weighing less than 2,000 g did not receive their first HepB birth dose according to ACIP recommendations. Strategies are needed to improve timely HepB vaccination in this high-risk population. KEY POINTS · Low birth weight infants are at increased risk for vaccine preventable diseases.. · Many of these vulnerable infants failed to receive their first hepatitis B vaccine on time.. · This study identified key factors associated with timely hepatitis B vaccination..

Abstract
Background The initiation of a new drug, for instance, the coronavirus disease 2019 (COVID-19) vaccine in children could be a source of major concern for parents. This study aims to determine the willingness of parents in Malaysia to vaccinate their children younger than 12 years against COVID-19. Methods An online cross-sectional survey was conducted nationwide in Malaysia from August 29, 2021, to October 17, 2021. Parents with children younger than 12 years were enrolled via the snowball sampling method. Results The analysis included data from 3,528 parents (79.5%) of the 4,438 survey responses received. Of these parents, 2,598 (73.6%) were willing, 486 (13.8%) were not willing, and 444 (12.6%) were still hesitant to vaccinate their children against COVID-19. Single parents (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.32–3.04; P = 0.001), parents with secondary or lower education (OR, 1.5; 95% CI, 1.21–1.96; P < 0.001), healthcare workers (OR, 1.7; 95% CI, 1.34–2.26; P < 0.001), parents who had significant contact with COVID-19 (OR, 1.3; 95% CI, 1.09–1.63; P = 0.006), and parents who had been vaccinated against COVID-19 (OR, 15.4; 95% CI, 9.76–24.33; P < 0.001) were found more willing to immunize their children. The common reasons for vaccination given by parents who were willing to immunize their children include protection of children (99.4%), protection of other family members (99.3%), and effectiveness (98.2%). The common reasons against vaccination given by parents who were not willing to immunize their children were uncertainty about the new vaccine (96.1%), concerns about vaccine contents (93.2%), limited vaccine information from physicians (82.3%), and the belief of vaccine was unsafe (79.8%). Conclusions In this study, nearly three-quarters of parents were willing to vaccinate their children younger than 12 years against COVID-19. The parents’ history of COVID-19 vaccination was the strongest independent predictor of their willingness to vaccinate their children. Therefore, future health education for the COVID-19 vaccine should focus on parents who are prone to vaccine refusal or hesitation, address the common reasons for vaccine refusal, and highlight the vaccine’s benefits.

Abstract
Background
In 1995, the CDC recommended one-dose routine varicella immunization for children <12 years of age, expanding its recommendation to two doses in 2006. Today, with widespread varicella vaccination coverage, an estimated 3.5 million cases of varicella, 9,000 hospitalizations, and 100 deaths are prevented annually in the United States. Since varicella infections are now uncommon, health care providers (HCPs) may not recognize varicella infections and may prescribe inappropriate treatment.
Methods
An online survey of HCPs was conducted to assess recognition and management of varicella infections. Responses to eight varicella vignettes describing patients with varying varicella symptoms were analyzed and descriptive analyses performed. Stratified analysis comparing responses of those licensed before and in/after 1996 was also performed.
Results
153 HCPs (50 nurse practitioners, 103 doctors) completed the survey. Mean age of respondents was 44 years. 62% were female, and 82% were licensed before 1996. Varicella infection was correctly diagnosed 79% of the time. HCPs correctly recognized uncomplicated varicella vignettes 85% of the time versus 61% of the time for complicated varicella vignettes. Antibiotics were recommended 17% of the time and antivirals 18% of the time, of which 25% and 69% (respectively) were not appropriate per guidelines. HCPs licensed before 1996 were better able to recognize varicella compared to those licensed later, but prescribed more antimicrobials medications to treat varicella.
Conclusions
Although most HCPs recognized varicella infection, a sizable proportion could not recognize cases with complications, and some of the varicella cases were inappropriately treated with antibiotics and/or antivirals. Additional HCP training and high vaccination coverage are important strategies to avoid inaccurate diagnoses and minimize unnecessary exposure to antimicrobial/antiviral therapies.

Abstract
Objective To examine psychosocial, sociodemographic, medical, and coronavirus disease 2019 (COVID-19) experiences as correlates of COVID-19 vaccination intentions among parents of children with type 1 diabetes (T1D). Methods 121 parents of children with T1D (Mchild age = 7.78 ± 1.70; MA1c = 8.3% ± 1.5%) in the mid-Atlantic and Southwest regions completed self-report measures in February to March 2021. Results Parents’ general vaccination behaviors and attitudes were associated with COVID-19 vaccination intentions. Child insurance type and social distancing adherence were associated with vaccination intention in the Southwest site. Higher A1c was associated with lower intention. Vaccine safety was the top reported concern. Conclusions COVID-19 vaccination intentions are important to address in parents of youth with health conditions.

Rev Epidemiol Sante Publique 2022; 70:123-131. [PMID: 35428543 PMCID: PMC8958178 DOI: 10.1016/j.respe.2022.02.004] [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: 06/16/2021] [Revised: 01/21/2022] [Accepted: 02/25/2022] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVES To report the characteristics of vaccine-hesitant individuals in a French-speaking adult population in the context of the SARS-CoV-2 pandemic; and to identify predictors of hesitancy about Covid-19-related vaccines. METHODS Between April and May 2020, 1640 French-speaking adults participating in an online cohort were classified according to their attitudes towards vaccination as: "hesitant", "anti-vaccination", and "pro-vaccination". Descriptive statistics, univariate multinomial regression models and multivariate analyses were compiled and carried out. RESULTS At the time of inclusion, compared to pro-vaccination participants, hesitant participants were more frequently females (p=0.044), not annually vaccinated against flu (p=0.026), less optimistic about the discovery of a treatment against Covid-19 in a few months (p<0.001), less ready to undergo this treatment (p<0.001), presenting less trust in the ability of public health authorities to control the pandemic (p=0.036) and reporting lower scores on knowledge-related scales (p values from <0.001 to 0.002). Univariate analyses confirmed these results with odds ratios ranging from 1.51 [1.05-2.17] to 2.19 [1.56-3.07]. In the multivariate models, the remaining variables associated with hesitant compared to pro-vaccination attitudes were discovery of a treatment against Covid-19 in a few months (OR=2.57 [1.73-3.81]), being ready to undergo this treatment (OR=7.07 [4.89-10.22]), digital vaccine literacy (OR=1.70 [1.14-2.54]) and general health literacy (OR=1.49 [1.03-2.15]). DISCUSSION In a continuum of relative acceptance of Covid-19-related vaccines, hesitant individuals were situated in between the behaviours and characteristics of pro-vaccination and anti-vaccination groups. While their characteristics were in line with the literature, this study was the first to report data on health literacy, digital vaccine literacy and capacity to detect fake news associated with vaccine hesitancy. CONCLUSIONS While failing to identify straightforward predictors, findings suggest that continued education and communication campaigns focused on improving vaccine literacy, particularly among women younger than 35 years, could heighten the proportion of persons accepting vaccination.

HPV Vaccination: An Underused Strategy for the Prevention of Cancer. Curr Oncol 2022; 29:3780-3792.

Abstract
Human papillomavirus (HPV) vaccination prevents cervical, head and neck, and anogenital cancers. However, global HPV vaccine coverage falls short of global targets and has seen unexpected and dramatic declines in some countries. This paper synthesizes the impact of HPV on the global burden of cancer and the potential benefit of HPV vaccination. Approximately 5% of the world’s cancers are specifically attributed to HPV. While the greatest global burden of HPV is cervical cancers in low- and middle-income countries, HPV-associated head and neck cancers are increasing in high-income countries and have surpassed cervical cancer as the primary HPV-associated cancer in some countries. Therefore, it is also critical to improve gender-neutral HPV vaccination. Understanding the modifiable drivers of vaccine acceptance and uptake is important for increasing HPV vaccination. The Behavioural and Social Drivers of Vaccination framework is broadly applied to identify key factors associated with HPV vaccination including domains concerning practical issues, motivation, social processes, and thinking and feeling. Among the behavioural strategies available to reduce the incidence and mortality of cancer, increasing HPV vaccination stands out as having unrealized potential to prevent disease, financial cost, and psychological distress. An understanding of the shifting burden of HPV and the factors associated with vaccination can be leveraged to regularly measure these factors, develop interventions to promote vaccine uptake, and improve global HPV vaccine coverage. Future research in diverse contexts is necessary to investigate the barriers and facilitators of global HPV vaccination.

Abstract
The COVID-19 pandemic has emerged as a major public health issue, with vaccines serving as a vital preventive strategy to lower the global burden. Yet, despite national and local mandates, key sectors of the population continue to demonstrate lower compliance rates. In the United States, young adults have the lowest vaccination rates among the adult population. The goal of our study was to utilize the largest state-health survey to assess the key determinants of such hesitancy in order to create targeted interventions for the most at-risk groups to ensure equitable outcomes in disease prevention. We utilized the latest available California Health Interview Survey, a population-based complex probability survey, to evaluate determinants of vaccine hesitancy among young adults. Survey-weighted descriptive statistics, bivariate statistics, and multivariable logistic regression analyses were conducted. All statistical tests used p less than 0.05 to determine statistical significance. A total of 1203 respondents, representative of 4,027,462 young adults (ages 18–25 years) were included in our study. Our primary findings note that 24% of participants reported they would not be willing to take the COVID-19 vaccination. Prevalence of vaccine hesitancy was also significantly higher among young adults who were current smokers (including electronic cigarettes), when compared to non-current smokers (36% vs. 22%). Further, the highest prevalence was also noted among young adults who identified as African-American (51%), had a high school degree or less (34%), those who were overweight or obese (28%), and reported a poor health status (22%). Multivariable regression analysis demonstrated that current smokers, as compared to non-current smokers, had more than double the odds of reporting COVID-19 vaccine hesitancy. African-American young adults or young adults with a high school degree or less were both independently associated with at least a three-fold increase in vaccine hesitancy. Participants with psychological distress, however, were more likely to be accepting of the vaccine. Public health efforts to improve vaccine compliance need targeted efforts, including building trust in the healthcare system for African-Americans and promoting easier access and knowledge of vaccines among those with a high school degree or less, as well as young-adults who are currently smoking, with such efforts targeting behavioral interventions focused on risk aversion.

Abstract
Children under the age of 5, will likely all be offered vaccination against SARS-CoV-2 soon. Parental concerns over vaccination of children are long standing and could impede the success of a vaccination campaign. In the UK, a trusted source to inform vaccination choices is the NHS website. Here we used a randomized controlled experiment of framing effects in NHS information content for COVID-19 and flu with 550 mothers under the age of 5. We compared both vaccination offers following two commonly used frames in vaccination informational campaigns: alerting to the risks of no vaccination for the child itself vs. those in their community. We find that vaccination intention was twice as high when risks to the child are emphasized, relative to risks to the community. Exploratory analyses suggest that these effects may differ between white and non-white mothers. Whilst communication directed at adult vaccination against COVID-19 generally focuses on risks of infecting others, communication about vaccination of children may benefit from emphasizing risks to the children themselves. This pattern is in line with flu vaccination research from pre-COVID-19 times.

Abstract
BACKGROUND Vaccination, albeit a necessity in the prevention of infectious diseases, requires appropriate strategies for addressing vaccine hesitancy at an individual and community level. However, there remains a glaring scarcity of available literature in that regard. Therefore, this review aims to scrutinize globally tested interventions to increase the vaccination uptake by addressing vaccine hesitancy at various stages of these interventions across the globe and help policy makers in implementing appropriate strategies to address the issue. METHODS A systematic review of descriptive and analytic studies was conducted using specific key word searches to identify literature containing information about interventions directed at vaccine hesitancy. The search was done using PubMed, Global Health, and Science Direct databases. Data extraction was based on study characteristics such as author details; study design; and type, duration, and outcome of an intervention. RESULTS A total of 105 studies were identified of which 33 studies were included in the final review. Community-based interventions, monetary incentives, and technology-based health literacy demonstrated significant improvement in the utilization of immunization services. On the other hand, media-based intervention studies did not bring about a desired change in overcoming vaccine hesitancy. CONCLUSION This study indicates that the strategies should be based on the need and reasons for vaccine hesitancy for the targeted population. A multidimensional approach involving community members, families, and individuals is required to address this challenging issue.

Does Hospitalization Change the Perception of COVID-19 Vaccines among Unvaccinated Patients? Vaccines (Basel) 2022; 10:vaccines10030476.

Abstract
The COVID-19 vaccination has been the subject of unprecedented misinformation, false news, and public concerns. This study presents a unique analysis comprising persons who were not vaccinated and became ill. It investigates reasons for not vaccinating and evaluates how the personal experience of COVID-19 affected further attitudes and decisions related to health. The study included 730 consecutive unvaccinated patients hospitalized in 12 centers in Poland during the autumn 2021 pandemic wave. The most frequent reason behind the refusal to receive the vaccine was concern over the adverse effects, disbelief that the vaccine was sufficiently tested, and one’s conviction that COVID-19 will not affect a patient. Online information, friends, spouse, children/grandchildren, and other family members were most often the source of discouragement from vaccination. Most individuals regretted their decision not to receive a vaccine (66.0%), declared to promote COVID-19 vaccination after discharge (64.0%), and to receive a COVID-19 vaccine in the time recommended for convalescents (69.5%). Individuals expressing no regrets of vaccine refusal more frequently revealed conspiracy beliefs. The study shows that personal experience with severe COVID-19 can influence the perception of vaccination, but approximately one-third of unvaccinated hospitalized patients still appear to express vaccine hesitancy.

Abstract
INTRODUCTION Parental vaccine hesitancy can be a barrier to routine childhood immunization and contribute to greater risk for vaccine-preventable diseases. This study examines the impact of parental vaccine hesitancy on childhood vaccination rates. METHODS This study assessed the association of parental vaccine hesitancy on child vaccination coverage with ≥4 doses of diphtheria, tetanus toxoid, and acellular pertussis vaccine; ≥1 dose of measles, mumps, and rubella vaccine; up-to-date rotavirus vaccine; and combined 7-vaccine series coverage for a sample of children aged 19-35 months using data from the 2018 and 2019 National Immunization Survey-Child (N=7,645). Adjusted differences in multivariable analyses of vaccination coverage were estimated among vaccine hesitant and nonhesitant parents and population attributable risk fraction of hesitancy on undervaccination, defined as not being up to date for each vaccine. RESULTS Almost a quarter of parents reported being vaccine hesitant, with the highest proportion of vaccine hesitancy among parents of children who are non-Hispanic Black (37.0%) or Hispanic (30.1%), mothers with a high school education or less (31.9%), and households living below the poverty level (35.6%). Childhood vaccination coverage for all vaccines was lower for children of hesitant than nonhesitant parents, and the population attributable fraction of hesitancy on undervaccination ranged from 15% to 25%, with the highest percentage for ≥1 dose of measles, mumps, and rubella vaccine. CONCLUSIONS Parental vaccine hesitancy may contribute up to 25% of undervaccination among children aged 19-35 months. Implementation of strategies to address parental vaccine hesitancy is needed to improve vaccination coverage for children and minimize their risk of vaccine-preventable diseases.

Abstract
Presently, the second wave of COVID-19 pandemic is driving the world towards a devastating total failure of the healthcare system. The purpose of the review is to search for the studies reporting on the implication of herd immunity into a naïve population through age specific mass vaccination. This review is based on selected publications on the effect herd immunity to COVID 19 in communities. We searched published scientific articles, review articles, reports, published in 2020 as well as read some basic, cult publications related to establishment of indirect immunity to a population. We have focused on use of application of vaccine induced herd immunity into community to confer indirect immunity against COVID-19 and searched on electronic databases, including PubMed (http://www.pubmed.com), Scopus (http://www.scopus.com), Google Scholar (http://www.scholar.google.com), Web of Science (www.webofscience.com) and Science Direct by using key words such as Herd immunity, indirect or passive immunization, Coronavirus disease 2019 (COVID-19), severe acute respiratory syndrome, coronavirus 2 (SARS-CoV-2), and immune-technique. This review proposes the implication of mass vaccination-induced herd immunity in a population to curb the infection, and to every individual in a given population irrespective of their age.
