Abstract
This study aimed to investigate the knowledge about, attitudes toward, and acceptance and predictors of receiving the mpox vaccine among Chinese cancer patients. Patients were selected using a convenience sampling method. A web-based self-report questionnaire was developed to assess cancer patients' knowledge, attitudes, and acceptance regarding the mpox vaccine. Multivariate logistic regression analysis was used to determine predictors of acceptance of the mpox vaccine. A total of 805 cancer patients were included in this study, with a vaccine hesitancy rate of 27.08%. Approximately 66% of the patients' information about mpox and the vaccine came from the mass media, and there was a significant bias in the hesitant group's knowledge about mpox and the vaccine. Multivariable logistic regression analysis suggested that retirement; chemotherapy; the belief that the mpox vaccine could prevent disease, that vaccination should be compulsory when appropriate and that the mpox vaccine prevents mpox and reduces complications; the willingness to pay for the mpox vaccine; the willingness to recommend that friends and family receive the mpox vaccine; and the belief that the mpox vaccine should be distributed fairly and equitably were factors that promoted vaccination. The belief that mpox worsens tumor prognosis was a driving factor for vaccine hesitancy. This study investigated the knowledge of cancer patients about mpox and the vaccine, evaluated the acceptance and hesitancy rates of the mpox vaccine and examined the predictors of vaccination intention. We suggest that the government scientifically promote the vaccine and develop policies such as free vaccination and personalized vaccination to increase the awareness and acceptance rate of the mpox vaccine.

The impact of the COVID-19 pandemic on childhood vaccination rates and the role of sociodemographic factors: A cohort study. Vaccine 2024; 42:126207. [PMID: 39121696 DOI: 10.1016/j.vaccine.2024.126207] [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: 04/26/2024] [Revised: 08/01/2024] [Accepted: 08/03/2024] [Indexed: 08/12/2024]
Abstract
OBJECTIVE This study examines the impact of the COVID-19 pandemic on both routine and non-routine vaccinations in infants during their initial 18 months of life, concurrently exploring the complex influence of sociodemographic factors. METHODS A cohort study was conducted, involving 2007 children in two distinct periods: pre-pandemic (January-June 2018) and pandemic (March 2020-May 2021). Participants were classified into two cohorts: 962 children in the 2018 group and 1045 children in the 2020-21 group. Utilizing unconditional logistic regression, the association between vaccination (complete or non-routine) and socioeconomic factors was examined, with adjustments for potential confounding variables such as age, breastfeeding, gestational age, and twins. RESULTS The study's analysis reveals that in the post-pandemic period, mothers were three times more likely to opt for non-routine vaccines (95% CI 2.25-4.23). However, no significant alterations were observed in routine vaccination rates. Protective factors for complete vaccination included having an employed mother, higher education, and a medium-to-high income. Conversely, a higher income was associated with a reduced likelihood of complete vaccination (OR 0.34, 95% CI 0.20-0.59). CONCLUSION Contrary to initial expectations, this study concludes that the COVID-19 pandemic did not have a substantial impact on childhood complete vaccination rates. Nevertheless, a noticeable increase in the choice of non-routine vaccination was observed. Sociodemographic factors, such as maternal education, income, and employment status, emerged as key influencers, particularly in the context of deciding on non-routine vaccinations.

Heinrich T, Kobayashi Y, Motta M. Which foreign vaccine should the government purchase in a pandemic? Evidence from a survey experiment in the United States. Soc Sci Med 2024; 347:116766. [PMID: 38502981 DOI: 10.1016/j.socscimed.2024.116766] [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: 10/12/2023] [Revised: 03/03/2024] [Accepted: 03/05/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND For many countries confronting a future pandemic, the initial vaccines available will come from abroad. Public hesitancy to receive these foreign vaccines is important, as it may create an incentive for governments to forego procuring them for public use. We investigate the influence of the vaccine's country of origin on public support for government procurement during the early stages of a pandemic and examine whether endorsements from the WHO can mitigate such biases. METHODS In the summer of 2023, we carried out a survey experiment of 1,110 U.S. residents where we asked respondents to rate their support for vaccine purchasing policies for 20 hypothetical vaccines (13,320 evaluations). We varied the vaccine's country of origin and its endorsement status from the WHO, while also randomizing other vaccine attributes. RESULTS Compared to foreign vaccines from countries Americans see favorable (e.g., Germany, the United Kingdom), those originating from less favorable countries (e.g., China, Russia), garnered lower support for government procurement. Our causal mediation analysis indicates that this country-of-origin effect is primarily driven by participants' sentiments toward the vaccine. Surprisingly, WHO endorsement does little to mitigate the effect of the vaccine's country of origin. These findings are consistent across various sample subsets and considerations of vaccine quality. CONCLUSION Our study advances previous work on vaccine country-of-origin effects by assessing its impact on policy preferences for procuring initial vaccines from overseas (as opposed to uptake intentions), identifying a mechanism by which vaccine favoritism occurs, and documenting that neither personal disease susceptibility nor vaccine quality fully mitigates country of origin effects. We conclude by discussing why the study of "vaccine diplomacy" ought to not only include interstate dynamics governing vaccine purchasing and availability but also consider vaccine-producing countries' more general reputations.

Abstract
The sharp rise in coronavirus cases in the United States, as well as other countries, is driven by variants such as the Omicron substrain, BA4 and BA5. Keeping up to date with COVID-19 vaccination and wearing masks are essential tools for mitigating the pandemic. Social media plays a vital role in sharing and exchanging information, but it also affects perceptions of social phenomena. In this study, we conducted sentiment analysis and topic modeling to investigate vaccine perception using 338,465 COVID-19 vaccine-related comments collected from January 2020 to May 2021 on Reddit. This study stands apart from prior COVID-related research on social media, particularly on Reddit, as it conducted separate analyses for each COVID vaccine and examines public sentiment with various societal events, including vaccine development progress and government responses to COVID. The findings reveal two notable spikes in the number of comments containing the keyword "vaccine". This suggests that discussions about vaccines tend to increase during times of significant social and political events, indicating that people's attention and interest in the topic are influenced by current events. Understanding the public perception of vaccines and identifying factors influencing vaccine perception could help propose appropriate interventions to promote vaccination.

Abstract
BACKGROUND Health literacy is the degree to which individuals can obtain, process, understand, and communicate health-related information. Health literacy among pregnant women, in particular, may have a significant impact on maternal and child health. In the United Arab Emirates, no previous studies have been carried out to investigate the health literacy levels of pregnant women. OBJECTIVE This study aimed to investigate antenatal health literacy levels and identify associated factors among pregnant Emirati women in the United Arab Emirates. DESIGN This analysis was based on the baseline cross-sectional data for pregnant women participating in the prospective cohort Mutaba'ah Study, recruited between May 2017 and August 2022. METHODS Participants completed a self-administered questionnaire during their antenatal visits that collected sociodemographic and pregnancy-related information. Adequacy of health literacy was assessed using the BRIEF health literacy screening tool with adequate health literacy defined as a score ⩾ 17. Regression modeling investigated the association between the pregnant women characteristics with having adequate health literacy level (ability to read and comprehend most patient education materials). RESULTS A total of 2694 responses to the BRIEF health literacy screening tool were analyzed. Approximately, three-quarters (71.6%) of respondents showed adequate health literacy, followed by marginal (22.8%), and limited (5.6%) health literacy levels, respectively. Higher education levels (adjusted odds ratio (aOR) = 1.74, 95% confidence interval = 1.46-2.08), employment (adjusted odds ratio = 1.35, 95% confidence interval = 1.10-1.65), and adequate social support (adjusted odds ratio = 1.69, 95% confidence interval = 1.26-2.28) were associated with adequate health literacy levels. Participants who expressed worry about birth were less likely to have adequate literacy levels (adjusted odds ratio = 0.70, 95% confidence interval = 0.58-0.85). CONCLUSION Nearly three-quarters of pregnant women have adequate health literacy. Nevertheless, measures including policies to sustain and enhance health literacy levels among all expectant mothers are required, with a specific focus on those having limited health literacy.

Abstract
Throughout the COVID-19 pandemic, the concept of solidarity has been invoked frequently. Much interest has centred around how citizens and communities support one another during times of uncertainty. Yet, empirical research which accounts and understands citizen's views on pandemic solidarity, or their actual practices has remained limited. Drawing upon the analysis of data from 35 qualitative interviews, this article investigates how residents in England and Scotland enacted, understood, or criticised (the lack of) solidarity during the first national lockdown in the United Kingdom in April 2020-at a time when media celebrated solidarity as being at an all-time high. It finds that although solidarity was practiced by some people, the perceived lack of solidarity was just as pronounced. We conclude that despite frequent mobilisations of solidarity by policy makers and other public actors, actual practices of solidarity are poorly understood-despite the importance of solidarity for public health and policy.

Abstract
BACKGROUND Increased psychological pressure on oral healthcare professionals (OHP) due to COVID-19 has been shown, yet little is known about the long-term psychological impacts. We aimed to study the psychological impact of COVID-19 and associated factors including perceived risk and preparedness and vaccination status among OHP in the first year after the lockdown period in Norway. METHODS A structured questionnaire sent electronically to dentists, dental hygienists and dental assistants inquired experiences and perceptions during the second year following the outbreak in Norway. The questionnaire comprised a COVID-19 fear scale and questions about risk perception, preparedness and vaccination status. Exploratory factor analysis (EFA) and Structural Equation Modeling (SEM) were used to assess psychological impact, perception of risk and preparedness according to vaccination status of the respondents. RESULTS The majority of the 708 respondents were female (92.8%), had ten or more years of work experience (67.1%), and worked in public dental clinics (95.9%). Fears and concerns related to COVID-19 were common, 72.6% feared getting infected and 85.4% feared infecting others. Of the 642 respondents who agreed that their workplaces handled the situation well, 55.6% were fully vaccinated. Three factors were retrieved from EFA: Insecurity, Instability and Infection. SEM showed that females were more concerned with Infection, and respondents with long clinical experience were less likely to express fear about Instability. Fully vaccinated individuals felt more insecure about becoming infected, and those agreeing that their workplaces handled the current situation well were concerned with Insecurity. CONCLUSIONS Despite widespread perception of adequate preparedness and high vaccine coverage, a considerable psychological impact and high levels of fear of COVID-19 were observed among the majority of OHP. Fully vaccinated individuals had a larger psychological burden than not fully vaccinated and those with unknown vaccination status. These findings can inform means and interventions to reduce negative impacts of fear in populations with a high psychological burden.

Abstract
Vaccine hesitancy has dramatically decreased the speed of vaccination and stalled global health development. While the factors influencing vaccine hesitancy and mitigation measures have been explored in depth by existing studies, research from the perspective of human interaction is lacking. Based on the theory of collective action, this paper analyzes how free riding behavior affects vaccine hesitancy and how the vaccine hesitancy caused by free riding behavior can be solved. Using 2,203 survey data sets from China, this paper examines the influence of the collective action dilemma - represented by free riding behavior - on COVID-19 vaccine hesitancy. The empirical results show that the existence of free riding behavior is an essential cause of vaccine hesitancy. Based on this conclusion, this paper discusses how to further alleviate the problem of vaccine hesitancy caused by collective action dilemmas by promoting cooperation. The findings of this paper may be helpful to promote various types of vaccines and further suggest that countries should assume the perspective of solving the collective action dilemma to achieve increased vaccination rates.

Abstract
The COVID-19 vaccine development timelines offered a unique opportunity to explore the public's vaccine intention in an unusual situation characterised by great uncertainty about the vaccine's features and the disease it intended to prevent. To advance our knowledge of vaccine intention mechanisms under these unusual circumstances, to plan effective vaccination strategies, and to better direct communication efforts in similar scenarios, this study explored i) COVID19-related information needs, information-seeking behaviours, and perceived trustworthiness of news media; ii) COVID-19 vaccination intention and its determinants, during the first wave of COVID-19 pandemic in Italy. In particular, it was investigated whether and to what extent the perception of severity and susceptibility to the infection, trust in authorities, and demographics shaped people's vaccine intention. Between April and May 2020 in a cross-sectional study, 1373 Italian participants completed an online survey measuring demographic features, perception of the disease severity, disease risk perception, COVID19-related worry, disease-related information needs and behaviours, vaccination intention, and level of trust in authorities and news media. The leading information needs were the COVID-19 incubation period and transmission modalities, with the majority of people actively looking for information from one to three times a day. Despite uncertainty around the details of a COVID-19 vaccination, 68% of participants reported intending to be vaccinated for COVID-19. Greater COVID-19 vaccination intention was associated with having a regular history of seasonal flu vaccine, a greater COVID19-related worry, a higher perception of disease severity, and a higher trust in the Government. These findings further our understanding of vaccine intention in a pandemic scenario where a vaccine is still hypothetical and provide valuable information on the public's representation of the infection and future acceptance of a vaccine to inform the development of communication interventions aiming to maximise adherence to vaccination programmes and to modify disease-related dysfunctional representations.

Abstract
The aim of the study was to develop and validate the Multidimensional Covid-19 Vaccine Hesitancy Scale (CoVaH), a self-report measure to assess the beliefs and attitudes beneath vaccination hesitancy and reasons for vaccine refusal in the context of Covid-19. A sample of 1503 Hungarian respondents filled out the scale. Exploratory and confirmatory factor analysis was conducted to identify latent constructs underlying participants' responses. Findings show a robust three-factor solution for the 15-item CoVaH with high factor loadings on each factor: skepticism, risk perception and fear of Covid-19 vaccine. The CoVaH displayed very good fit indices (KMO = .94, RMSEA = 0.049, CFI = .983) and internal consistencies (α values > .89) and was found to have proper convergent, concurrent and discriminant validity in identifying Covid-19 vaccine hesitancy in the general population. The new scale adds to the literature through the identification of the fear of COVID-19 vaccines, as a newly highlighted explanatory variable of COVID-19 vaccine hesitancy, besides the other formerly identified components. The scale, available in English and Hungarian, allows the assessment of vaccine uptake hesitancy and has the potential to help targeted interventions, considering individual factors that interfere with vaccination acceptance.

Abstract
Vaccination is a vital component in the battle against outbreaks of infectious diseases. Recognizing parents' reluctance to vaccinate their children is even more critical now, given the ongoing threat of a COVID-19 pandemic. Conspiracy theories, vaccination safety concerns, parental efficacy and risk perception, and a lack of confidence in science all influence intention. To investigate how these variables interact with vaccination behavior against COVID-19, we developed a model with psychosocial factors serving as the predictor and mistrust in science and vaccine knowledge serving as the mediator. In order to validate the model, the parents' intentions regarding their children's vaccination with COVID-19 were used. The study included 454 Pakistani parents who completed an online questionnaire assessing their intention to vaccinate their children. We analyzed the data using structural equation modeling (SEM). A significant level of vaccine hesitation is due to belief in vaccine conspiracy theories, and vaccine safety concerns were investigated. A surprising correlation exists between risk perception and vaccination intentions, followed by parental self-efficacy. It is significant to note that vaccine knowledge mediated conspiracy beliefs, risk perceptions, and intentions fully but partially mediated parental self-efficacy. Conspiracy theories were mediated by a mistrust in science, while perceptions of risk and vaccine safety were partially mediated. The findings of this research were used to develop sensible policy reforms and public health campaigns to encourage vaccination against both common infections such as measles, human papillomaviruses, or pertussis, and novel diseases such as COVID-19.

Abstract
Background and Aim: The development of a coronavirus disease 2019 (COVID-19) vaccine is ongoing. This study aimed to prepare for public acceptance of the vaccine. There is a need to identify the current acceptance and potential barriers to receiving a COVID-19 vaccine in Yemen. Understanding the hesitancy and acceptance of a COVID-19 vaccine are crucial to develop local evidence-based interventions.
Materials and Methods: Twenty students were interviewed in this study. An interview guide was developed and it addressed the willingness to accept a future COVID-19 vaccine. In-depth interviews were conducted, transcribed, and manually analyzed.
Results: The majority of participants agreed that they would take a COVID-19 vaccine for several reasons, including protection for themselves, their families, and others and to stop the spread of COVID-19, for which the vaccine is important, as in other routine vaccinations. However, some participants shared that they would not take the COVID-19 vaccine due to the following reasons: Concerns regarding the safety of the vaccine; feeling fit and healthy, and thus considering themselves to have strong immunity; feeling that the vaccine was manufactured in a rushed manner and thus it would require approval by the World Health Organization; being previously infected with COVID-19 and considering themselves protected, and placing their trust in God and believing no vaccine was needed.
Conclusion: The willingness to receive a future COVID-19 vaccine was high among medical students. However, some students hesitated to take the vaccine. Therefore, mass media interventions are required to maximize vaccine uptake.

Abstract
OBJECTIVE To evaluate the factors associated with the intention to participate in COVID-19 vaccine clinical trials in the Peruvian population. METHODS Cross-sectional study and secondary analysis of a database that involved Peruvian population during September 2020. The Poisson regression model was used to estimate the associated factors. RESULTS Data from 3231 individuals were analyzed, 44.1% of whom intended to participate in COVID-19 vaccine clinical trials. Factors associated with the outcome were being male (RPa: 1.25; 95% CI: 1.15-1.35), being from the highlands region (RPa: 1.18; 95% CI: 1.09-1.28) or jungle (RPa: 1.30; 95% CI: 1.15-1.47), having a relative that is a healthcare professional (PRa: 1.16; 95% CI: 1.06-1.28), using a medical source of information (PRa: 1.28; 95% CI: 1.17-1.41), and trusting in the possible effectiveness of vaccines (PRa: 1.40; 95% CI: 1.29-1.51). The main reason for not participating in the trial was the possibility of developing side effects (69.80%). CONCLUSION There is an urgent need to generate a perception of safety in COVID-19 vaccine clinical trials, to increase the population's intention to participate in these studies, and to provide evidence-based information about the vaccine.

COVID-19 Vaccination Intention Associated with Behaviors towards Protection and Perceptions Regarding the Pandemic. J Pers Med 2022; 12:jpm12020295. [PMID: 35207785 PMCID: PMC8877246 DOI: 10.3390/jpm12020295] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 02/10/2022] [Accepted: 02/13/2022] [Indexed: 01/19/2023] Open
Abstract
Background: The impressively rapid availability of different types of COVID-19 vaccines and, on the other hand, the degree of their effectiveness as opposed to the likelihood of serious or non-serious side effects place a fairly large percentage of the population at a crossroads regarding the choice to get vaccinated or not, hence threatening achievement of total immunization coverage and full immunity. This study aimed to assess COVID-19 vaccination intention in Greece regarding protection behaviors and perceptions of the pandemic. Methods: A total of 3753 participants completed a specially designed electronic questionnaire anonymously and voluntarily. The study population consisted of healthcare workers, students, members of professional societies, teachers, and professors. The questionnaire was composed of four parts pertaining to demographic data and possible changes in hygiene attitudes during the COVID-19 pandemic. Results: In total, 43.3% of the participants stated that SARS-CoV-2 poses a significant risk. The most widespread protection practice was avoiding crowded places (90.1%), followed by reducing the use of public transport (86.1%) and washing their hands with soap and water more often than usual (84.2%). Women undertook significantly more behavioral changes than men and participants of other nationalities. About half of the participants (44%) implemented seven behavioral changes. Lower personal and general perceived risk due to COVID-19 was significantly associated with lower intention to get vaccinated. Conclusion: Strong hesitancy was observed towards COVID-19 vaccination. There is a need for further studies to be conducted to investigate the benefits and safety of vaccines for the purpose of better informing the public. Healthcare personnel can and should play a key role in this process.

Under-Vaccination in Adults: Qualitative Insights Into Perceived Barriers Reported by Vaccine Supporters, Undecided and Refuters. J Prim Prev 2021; 42:625-640.

Abstract
Although vaccination is one of the most cost-effective ways of preventing disease, vaccine hesitancy has been included among the ten threats of global health. Addressing low adult vaccination rates requires an adequate understanding of people's views. We explored perceived barriers to immunization among under-vaccinated adults to identify potential differences among vaccine supporters, refuters, and those who are undecided. We conducted a multi-center, mixed-methods study at 23 primary care practices in Greece. Each day, we asked three new randomly-selected adult healthcare users who attended the practice over the course of 30 consecutive working days. We used thematic content analysis to analyze their written answers to open-ended questions that addressed reasons for not getting vaccinated. Out of 1571 participants, two-thirds reported they were under-vaccinated as adults, thus accounting for three out of five of the supporters and the vast majority of the undecided and refuters. “Concerns/fears,” a “perception of low susceptibility to disease due to good health status,” the “absence of healthcare professional’s recommendation,” and “previous negative experiences” were four themes common to all three groups. Additional barriers reported by supporters and the undecided included “knowledge gaps about the necessity of adult vaccination,” “negligence,” and lack of “accessibility.” Among refuters, additional themes identified were “mistrust in pharmaceutical companies” and “disbelief in vaccine effectiveness.” In conclusion, under-vaccination is common, not only among refuters or the undecided, but also among supporters of adult vaccination. We found similarities and differences in under-vaccinated adults’ perceived barriers, depending on their individual perspectives. Physicians and public health services should take into consideration the impact of the wide range of attitudes and beliefs in their effort to address the underlying barriers to vaccination compliance as they attempt to increase vaccination coverage in adults.

Abstract
BACKGROUND Influenza vaccination has been associated with decreased risk of influenza-related infections. However, associations between influenza vaccination and the severity of influenza cases have not been systematically summarized. We conducted a meta-analysis to evaluate whether influenza vaccination could attenuate symptom severity in vaccinated influenza patients. METHODS A systematic literature search was performed using the PubMed, Web of Science, EMBASE, and Scopus databases. A quantitative synthesis of the data was conducted using a fixed/random effects model in the meta-analysis. RESULTS A total of seven studies, involving 6342 vaccinated and 7036 non-vaccinated patients were included. Compared with non-vaccinated, vaccinated patients were significantly less likely to develop a fever (OR = 0.66, 95% CI: 0.43-0.89), be admitted to the ICU (OR = 0.79, 95% CI: 0.64-0.97), suffer mortality (OR = 0.55, 95% CI: 0.34-0.89), stay in the ICU (WMD = -1.37, 95% CI: -2.15 to -0.60) or stay in the hospital (WMD = -0.32, 95% CI: -0.61 to -0.04). CONCLUSION Those benefits that could be highlighted in the communication material to enhance the uptake of influenza vaccination among both the public health nurses and the community as a whole.

Abstract
BACKGROUND Background: Social media has become an important source of health information during the COVID-19 period. Very little is known about the potential mental impact of social media use on pregnant women. OBJECTIVE Objective: The present study examined the association between using social media for health information, risk perception for COVID-19, worry due to COVID-19 and depression among pregnant women in China. METHODS Methods: A total of 4,580 pregnant women were recruited from various provinces of China and completed an online survey in March 2020. RESULTS Results: More than one-third (39.2%) reported always using social media for health information. Results from structural equation modeling showed that frequency of social media use for health information was positively associated with perceived susceptibility (β = .05, p <.001) and perceived severity of COVID-19 (β = .12, p < .001), which in turn, were positively associated with worry due to COVID-19 (β = .19 and .72, p <.001). Perceived susceptibility (β = .09, p <.001), perceived severity (β = .08, p <.001), and worry due to COVID-19 (β = .15. p <.001) all had a positive association with depression. Results from bootstrapping analysis showed that the indirect effects of frequency of social media use for health information on worry due to COVID-19 and depression were both significant. CONCLUSIONS Conclusions: The present study provided empirical evidence on how social media use for health information might have a negative impact on pregnant women's mental health. Interventions are needed to equip them with the skills to use social media properly. CLINICALTRIAL

Abstract
Examine the factors that promote vaccine hesitancy or acceptance during pandemics, major epidemics and global outbreaks. A systematic review and thematic analysis of 28 studies on the Influenza A/H1N1 pandemic and the global spread of Ebola Virus Disease. We found seven major factors that promote vaccine hesitancy or acceptance: demographic factors influencing vaccination (ethnicity, age, sex, pregnancy, education, and employment), accessibility and cost, personal responsibility and risk perceptions, precautionary measures taken based on the decision to vaccinate, trust in health authorities and vaccines, the safety and efficacy of a new vaccine, and lack of information or vaccine misinformation. An understanding of participant experiences and perspectives toward vaccines from previous pandemics will greatly inform the development of strategies to address the present situation with the COVID-19 pandemic. We discuss the impact vaccine hesitancy might have for the introduction and effectiveness of a potential COVID-19 vaccine. In particular, we believe that skepticism toward vaccines can still exist when there are no vaccines available, which is contrary to contemporary conceptualizations of vaccine hesitancy. We recommend conducting further research assessing the relationship between the accessibility and cost of vaccines, and vaccine hesitancy.

Abstract
Background: The intention of Chinese people older than age 5 to accept the pertussis vaccination is unknown, which is important for the future design of an effective pertussis vaccination program in China.Method: We conducted a cross-sectional survey among people older than age 5 in China. A 24-item questionnaire was used to explore the determinants of intention to accept a pertussis vaccination, and for children and adolescents (≦15 years old), their guardian was required to help answer the questionnaire on their behalf. Univariate and multivariate logistic regression was used to analyze the influencing factors of intention.Results: A total of 3,041 individuals participated in our survey and 3025 completed the questionnaire, among which 1938 (64.07%) reported a positive intention to be vaccinated. A multiple logistic regression analysis revealed that the main positive factors for the intention to accept pertussis vaccination were younger age (Odd ratio [OR] 0.838, P < .001), higher educational attainment (OR 1.171, P = .002), no hospitalization because of the most recent cough (OR 2.468, P < .001), awareness about pertussis (OR 1.958, P < .001), and consideration of pertussis vaccination to be safe (OR 1.450, P = .026).Conclusion: There is a relatively high level of intention to receive the pertussis vaccine among people older than age 5 in China. Future pertussis vaccination strategies geared at them should consider focusing on middle-aged and older individuals and those with a low education as well as strengthen the promotion of disease characteristics, vaccine effectiveness, and safety.

Abstract
Objectives: Young adults are essential to the effective mitigation of the novel coronavirus (SARS-CoV-2/COVID-19) given their tendency toward greater frequency of social interactions. Little is known about vaccine willingness during pandemics in European populations. This study examined young people's attitudes toward COVID-19 vaccines in Fall 2020. Methods: Data came from an ongoing longitudinal study's online COVID-19-focused supplement among young adults aged 22 in Zurich, Switzerland (N = 499) in September 2020. Logistic regressions examined young adults' likelihood of participating in COVID-19 immunization programs. Results: Approximately half of respondents reported being unlikely to get vaccinated against COVID-19. Compared to males, females were more likely to oppose COVID-19 vaccination (p < 0.05). In multivariate models, Sri Lankan maternal background and higher socioeconomic status were associated with a greater likelihood of getting vaccinated against COVID-19 (p < 0.05). Respondents were more likely to report a willingness to get vaccinated against COVID-19 when they perceived 1) an effective government response (p < 0.05) and 2) their information sources to be objective (p < 0.05). Conclusion: This study communicates aspects important to the development of targeted information campaigns to promote engagement in COVID-19 immunization efforts.

Abstract
BACKGROUND This review aims to (i) identify and critique existing methods of community engagement for outbreak preparedness and response in high-income settings, and (ii) understand community members' experiences of community engagement, and their views and concerns towards pandemic planning/response. METHODS Following the PRISMA guidelines, a systematic review was conducted by searching Medline, Embase, PubMed, Global Health, CINAHL Plus and Scopus for publications from 2004 to June 2019. Potential literature was screened using explicit inclusion and exclusion criteria. Included studies were appraised using the Critical Appraisal Skills Programme Qualitative Research checklist. Those using deliberative approaches were appraised using additional criteria for judging deliberation quality. Thematic synthesis was then conducted. RESULTS Primary studies employed participatory research approaches, deliberative forums, interviews/focus groups to engage community members on pandemic planning/response with varying degrees of involvement and methodological rigour. This review indicates such endeavours must take into account instrumental and relational considerations: socioeconomic pressures; agency and capacity; diversity and divergent views; educate, communicate and engage; trust and transparency. CONCLUSION Community engagement for pandemic planning/response requires clear methods, processes and who 'community' constitutes. Instrumental and relational considerations must be addressed concurrently in pandemic planning/response to enhance preparedness for public health emergencies.

Tsimtsiou Z, Tsiligianni I, Papaioannou A, Gougourelas D, Kolokas K, Gkizlis V, Chatzimanolis E, Domeyer PRJ. Understanding what people think and feel about adult vaccinations and the associated barriers in Greece: Development and validation of the attitude towards adult vaccination (ATAVAC) scale. HEALTH & SOCIAL CARE IN THE COMMUNITY 2021; 29:818-828. [PMID: 33595159 DOI: 10.1111/hsc.13317] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 11/30/2020] [Accepted: 01/20/2021] [Indexed: 06/12/2023]
Abstract
Despite the unequivocal value of vaccination in reducing the global burden of infectious diseases, the anti-vaccination movement thrives. The vast majority of the existing validated tools explore attitudes regarding vaccination in children. The aim of our study was to develop and validate a scale assessing attitudes towards adult immunisation. This national cross-sectional study included adult healthcare users who visited 23 Greek Primary Healthcare Units. The development of the scale was the result of literature review, semi-structured interviews and pilot testing of its preliminary versions. The initial version contained 15 items measuring respondents' attitudes on a 6-point Likert scale. The sample was randomly split into two halves. Exploratory factor analysis, performed in the first sample, was used for the creation of multi-item scales; confirmatory factor analysis was used in the second sample to assess goodness of fit. Moreover, concurrent validity, internal consistency reliability, test-retest reliability and ceiling and floor effects were explored. The total sample consisted of 1,571 individuals. Overall 'Cronbach's alpha' (0.821) indicated good internal consistency. The initial exploratory factor analysis resulted in a three-factor model. The subsequent confirmatory factor analysis indicated that an 11-item version of the scale provided the best fit of the model to the data (RMSEA = 0.050, SRMR = 0.053, TLI = 0.937, CFI = 0.955, AIC = 24,999.949). All subscales ('value of adult vaccination', 'safety concerns' and 'perceived barriers') demonstrated strong concurrent associations with participants' attitudes and behaviour regarding vaccination (p < .001). No ceiling or floor effects were noted for any of the subscales (0.13%, 2.61% and 0.51%; 0.13%, 0.57% and 0.45% respectively). The 11-item ATAVAC scale proved to be a reliable and valid tool, suitable for assessing attitudes towards adult vaccination.

Abstract
This rapid scoping review has informed the development of the November 2020 United Nations Research Roadmap for the COVID-19 Recovery, by providing a synthesis of available evidence on the impact of pandemics and epidemics on (1) essential services and (2) health systems preparedness and strengthening. Emerging findings point to existing disparities in health systems and services being further exacerbated, with marginalized populations and low- and middle-income countries burdened disproportionately. More broadly, there is a need to further understand short- and long-term impacts of bypassed essential services, quality assurance of services, the role of primary health care in the frontline, and the need for additional mechanisms for effective vaccine messaging and uptake during epidemics. The review also highlights how trust—of institutions, of science, and between communities and health systems—remains central to a successful pandemic response. Finally, previous crises had repeatedly foreshadowed the inability of health systems to handle upcoming pandemics, yet the reactive nature of policies and practices compounded by lack of resources, infrastructure, and political will have resulted in the current failed response to COVID-19. There is therefore an urgent need for investments in implementation science and for strategies to bridge this persistent research–practice gap.

Vaccine Hesitancy among Italian Patients Recovered from COVID-19 Infection towards Influenza and Sars-Cov-2 Vaccination. Vaccines (Basel) 2021; 9:172. [PMID: 33670661 PMCID: PMC7922251 DOI: 10.3390/vaccines9020172] [Citation(s) in RCA: 54] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 02/11/2021] [Accepted: 02/16/2021] [Indexed: 11/17/2022] Open
Abstract
We aimed to assess the attitude towards influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations among coronavirus disease 2019 (COVID-19) recovered patients. We performed a cross-sectional study consisting of a standardized telephone interview carried out between September and November 2020 targeting a cohort of adult in- and out-patients that had recovered from COVID-19 after the first wave (March-May 2020) at Udine Hospital (Italy). Overall, 599 people participated (320 female, median age 53 years) and most had experienced an acute COVID-19 with mild illness (409, 68.3%). The majority were hesitant or undecided towards influenza (327, 54.6%) and SARS-CoV-2 (353, 59.2%) vaccines. Older age, public work exposure, and previous 2019 flu shots were the main factors associated with a positive attitude toward both vaccinations (p < 0.05). Being hospitalized during the acute COVID-19 phase was associated with the willingness to get a flu shot (94/272, 34.5%) but not SARS-CoV-2 vaccine (70/244, 28.7%). Vaccine hesitancy is diffuse and multifactorial also among COVID-19 recovered.

Intention to participate in a COVID-19 vaccine clinical trial and to get vaccinated against COVID-19 in France during the pandemic. Vaccine 2020; 38:7002-7006. [PMID: 32988688 PMCID: PMC7498238 DOI: 10.1016/j.vaccine.2020.09.041] [Citation(s) in RCA: 427] [Impact Index Per Article: 106.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 09/07/2020] [Accepted: 09/14/2020] [Indexed: 02/07/2023]
Abstract
INTRODUCTION The world is facing the COVID-19 pandemic. The development of a vaccine is challenging. We aimed to determine the proportion of people who intend to get vaccinated against COVID-19 in France or to participate in a vaccine clinical trial. METHODS We conducted an anonymous on-line survey from the 26th of March to the 20th of April 2020. Primary endpoints were the intention to get vaccinated against COVID-19 if a vaccine was available or participate in a vaccine clinical trial. RESULTS Three thousand two hundred and fifty nine individuals answered the survey; women accounted for 67.4% of the respondents. According to their statements, 2.512 participants (77.6%, 95% CI 76.2-79%) will certainly or probably agree to get vaccinated against COVID-19. Older age, male gender, fear about COVID-19, being a healthcare worker and individual perceived risk were associated with COVID-19 vaccine acceptance. Vaccine hesitancy was associated with a decrease in COVID-19 vaccine acceptance. One thousand and five hundred and fifty respondents (47.6% 95% CI 45.9-49.3%) will certainly or probably agree to participate in a COVID-19 vaccine clinical trial. Older age, male gender, being a healthcare worker and individual perceived risk were associated with potential acceptance to participate in a COVID-19 vaccine clinical trial. Vaccine hesitancy was associated with refusal for participation in a COVID-19 vaccine clinical trial. CONCLUSIONS Nearly 75% and 48% of the survey respondents were respectively likely to accept vaccination or participation in a clinical trial against COVID-19. Vaccine hesitancy will be the major barrier to COVID-19 vaccine uptake.

Pharmacy-based interventions to increase vaccine uptake: report of a multidisciplinary stakeholders meeting. BMC Public Health 2019; 19:1698.

Abstract
BACKGROUND Despite the existence of efficacious vaccines, the burden of vaccine-preventable diseases remains high and the potential health benefits of paediatric, adolescent and adult vaccination are not being achieved due to suboptimal vaccine coverage rates. Based on emerging evidence that pharmacy-based vaccine interventions are feasible and effective, the European Interdisciplinary Council for Ageing (EICA) brought together stakeholders from the medical and pharmacy professions, the pharmaceutical industry, patient/ageing organisations and health authorities to consider the potential for pharmacy-based interventions to increase vaccine uptake. We report here the proceedings of this 3-day meeting held in March 2018 in San Servolo island, Venice, Italy, focussing firstly on examples from countries that have introduced pharmacy-based vaccination programmes, and secondly, listing the barriers and solutions proposed by the discussion groups. CONCLUSIONS A range of barriers to vaccine uptake have been identified, affecting all target groups, and in various countries and healthcare settings. Ease of accessibility is a potentially modifiable determinant in vaccine uptake, and thus, improving the diversity of settings where vaccines can be provided to adults, for example by enabling community pharmacists to vaccinate, may increase the number of available opportunities for vaccination.

A review of documents prepared by international organizations about influenza pandemics, including the 2009 pandemic: a bibliometric analysis. BMC Infect Dis 2018; 18:383. [PMID: 30089459 PMCID: PMC6083574 DOI: 10.1186/s12879-018-3286-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Accepted: 07/31/2018] [Indexed: 11/19/2022] Open
Abstract
Background World Health Organization (WHO), the World Bank, UN System Influenza Coordination (UNSIC) and other international organizations released a series of documents to fight against the influenza pandemic. Those documents have great significance on guiding influenza pandemic preparedness and responses and providing a multilevel, multi-directional influenza pandemic prevention and control network for their member countries. This study focuses on the above-mentioned influenza pandemic preparedness guidelines with the aim of exploring the roles of the society, defining the relationship of different interventions and evaluating the planning on influenza pandemic preparedness. Methods Documents about pandemic influenza preparedness were retrieved from the official websites of the following three international organizations, World Health Organization (WHO), the World Bank, UN System Influenza Coordination (UNSIC) with the key words ‘pandemic’, ‘influenza’ and the Boolean combinations of these words as the retrieval strategy. Guidelines, research study and meeting reports were included in the study. The categories of the ministries/departments involved and their roles/responsibilities in pandemic influenza preparedness were summarized. Word frequency of selected vocabularies about pandemic influenza preventive measures were collected from the documents and the correlations between the word frequency of these measures were analyzed. Ochiai coefficient was employed to show the correlation between the word vocabularies. Results A total of 38 records on the topic of pandemic influenza preparedness were included. The responsibilities of the whole-of-society mentioned in the international organizations’ documents varied across the 2009 influenza pandemic period. Meanwhile, it had been emphasized that a comprehensive influenza prevention and control plan in every sector should be developed and evaluated. Because various measures were emphasized in the guidelines after 2009 pandemic influenza, the correlations between the word frequencies of the various influenza preventive measures became stronger after the pandemic influenza. Conclusions Responsibilities of ministries of education, ministries of energy, ministries of agriculture and animal health, ministries of communication and the business sector in the pandemic influenza preparedness were described more comprehensively in the international organizations’ documents in 2017. Better understanding the variations of the guidelines delivered by international organizations would be useful for the member countries to strengthen their influenza control network.

Abstract
Persons who read information about a hypothetical influenza strain with scientific (H11N3 influenza) or exotic-sounding (Yarraman flu) name reported higher worry and vaccination intentions than did those who read about strains named after an animal reservoir (horse flu). These findings suggest that terms used for influenza in public communications can influence reactions.

Results from national surveys on seasonal influenza vaccination programmes, 2008/2009 to 2014/2015. Vaccine 2017; 36:442-452. [PMID: 29287683 PMCID: PMC5777640 DOI: 10.1016/j.vaccine.2017.12.019] [Citation(s) in RCA: 174] [Impact Index Per Article: 24.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Revised: 12/06/2017] [Accepted: 12/07/2017] [Indexed: 11/04/2022]
Abstract
Background Influenza vaccination is recommended especially for persons at risk of complications. In 2003, the World Health Assembly urged Member States (MS) to increase vaccination coverage to 75% among older persons by 2010. Objective To assess progress towards the 2010 vaccination goal and describe seasonal influenza vaccination recommendations in the World Health Organization (WHO) European Region. Methods Data on seasonal influenza vaccine recommendations, dose distribution, and target group coverage were obtained from two sources: European Union and European Economic Area MS data were extracted from influenza vaccination surveys covering seven seasons (2008/2009–2014/2015) published by the Vaccine European New Integrated Collaboration Effort and European Centre for Disease Prevention and Control. For the remaining WHO European MS, a separate survey on policies and uptake for all seasons (2008/2009–2014/2015) was distributed to national immunization programmes in 2015. Results Data was available from 49 of 53 MS. All but two had a national influenza vaccination policy. High-income countries distributed considerably higher number of vaccines per capita (median; 139.2 per 1000 population) compared to lower-middle-income countries (median; 6.1 per 1000 population). Most countries recommended vaccination for older persons, individuals with chronic disease, healthcare workers, and pregnant women. Children were included in < 50% of national policies. Only one country reached 75% coverage in older persons (2014/2015), while a number of countries reported declining vaccination uptake. Coverage of target groups was overall low, but with large variations between countries. Vaccination coverage was not monitored for several groups. Conclusions Despite policy recommendations, influenza vaccination uptake remains suboptimal. Low levels of vaccination is not only a missed opportunity for preventing influenza in vulnerable groups, but could negatively affect pandemic preparedness. Improved understanding of barriers to influenza vaccination is needed to increase uptake and reverse negative trends. Furthermore, implementation of vaccination coverage monitoring is critical for assessing performance and impact of the programmes.

Abstract
We review behavioural change models (BCMs) for infectious disease transmission in humans. Following the Cochrane collaboration guidelines and the PRISMA statement, our systematic search and selection yielded 178 papers covering the period 2010-2015. We observe an increasing trend in published BCMs, frequently coupled to (re)emergence events, and propose a categorization by distinguishing how information translates into preventive actions. Behaviour is usually captured by introducing information as a dynamic parameter (76/178) or by introducing an economic objective function, either with (26/178) or without (37/178) imitation. Approaches using information thresholds (29/178) and exogenous behaviour formation (16/178) are also popular. We further classify according to disease, prevention measure, transmission model (with 81/178 population, 6/178 metapopulation and 91/178 individual-level models) and the way prevention impacts transmission. We highlight the minority (15%) of studies that use any real-life data for parametrization or validation and note that BCMs increasingly use social media data and generally incorporate multiple sources of information (16/178), multiple types of information (17/178) or both (9/178). We conclude that individual-level models are increasingly used and useful to model behaviour changes. Despite recent advancements, we remain concerned that most models are purely theoretical and lack representative data and a validation process.
