Vaccine Attitudes and Uptake Among Latino Residents of a Former COVID-19 Hotspot.

Early in the COVID-19 pandemic, the Centers for Disease Control and Prevention identified Prince William County (PWC), Va. as a hotspot with a high disease rate among Latinos. This study uses spatial, survey, and qualitative data to understand attitudes towards vaccine uptake among PWC Latinos. A quantitative analysis (n=266) estimates the association for vaccine acceptance among Latinos. Next, qualitative interviews with Latinos (n=37) examine vaccine attitudes. Finally, a spatial analysis identifies clusters of social vulnerability and low vaccine uptake in PWC and adjacent counties. Our findings show that a substantial proportion of PWC Latinos had low vaccination rates as of December 2022, two years after the vaccine's release. Side effects and safety and approval concerns were cited in both the quantitative and qualitative studies. Persistent vaccine disparities are concerning given the high hospitalization and mortality rates that prevailed among Latinos early in the pandemic.

Knowledge about, attitudes toward and acceptance and predictors of intention to receive the mpox vaccine among cancer patients in China: A cross-sectional survey.

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.

I want to be safe: understanding the main drivers behind vaccination choice throughout the pandemic.

BACKGROUND: Despite being a major advancement in modern medicine, vaccines face widespread hesitancy and refusal, posing challenges to immunization campaigns. The COVID-19 pandemic accentuated vaccine hesitancy, emphasizing the pivotal role of beliefs in efficacy and safety on vaccine acceptance rates. This study explores the influence of efficacy and safety perceptions on vaccine uptake in Italy during the pandemic. METHODS: We administered a 70-item questionnaire to a representative sample of 600 Italian speakers. Participants were tasked with assessing the perceived effectiveness and safety of each vaccine dose, along with providing reasons influencing their vaccination choices. Additionally, we conducted an experimental manipulation, exploring the effects of four framing messages that emphasized safety and/or efficacy on participants' willingness to receive a hypothetical fourth vaccine dose. Furthermore, participants were asked about their level of trust in the scientific community and public authorities, as well as their use of different information channels for obtaining COVID-19-related information. RESULTS: Our study reveals a dynamic shift in vaccine efficacy and safety perceptions throughout the COVID-19 pandemic, potentially influencing vaccination compliance. Initially perceived as more effective than safe, this assessment reversed by the time of the third dose. Beliefs regarding safety, rather than efficacy, played a significant role in anticipating future vaccinations (e.g., the booster dose). Safety-focused messages positively affected vaccination intent, while efficacy-focused messages showed limited impact. We also observed a changing trend in reasons for vaccination, with a decline in infection-related reasons and an increase in social related ones. Furthermore, trust dynamics evolved differently for public authorities and the scientific community. CONCLUSIONS: Vaccine perception is a dynamic process shaped by evolving factors like efficacy and safety perceptions, trust levels, and individual motivations. Our study sheds light on the complex dynamics that underlie the perception of vaccine safety and efficacy, and their impact on willingness to vaccinate. We discuss these results in light of bounded rationality, loss aversion and classic utility theory.

Heritage and hesitancy: how preference for traditional Chinese medicine influences vaccine attitudes.

Introduction: Vaccine hesitancy, amplified by the COVID-19 pandemic, is a pressing public health challenge. This study investigates the association between Traditional Chinese Medicine (TCM) preference and COVID-19 vaccine hesitancy within China. Methods: The study uses data from the 2021 Chinese General Social Survey (CGSS) (N = 2,690). Logistic regressions and Karlson-Holm-Breen (KHB) method are employed to analyzed the relationship between TCM preference and vaccine hesitancy. Results: The study reaffirms prior findings by revealing a robust and stable association between TCM preference and vaccine hesitancy, which remains unaffected by socioeconomic and demographic confounders, as well as institutional trust dynamics of healthcare system. Contrary to expectations, TCM enthusiasts do not exhibit vaccine hesitancy based on divergent epistemological views concerning vaccine risks and immunity acquisition compared to biomedicine. Discussion: This research enriches understandings of the intricate relations between healthcare paradigms and vaccine attitudes, inviting further inquiry into the role of CAM in shaping vaccination behaviors across different cultures and contexts. The insights bear significant public health implications for enhancing vaccine acceptance and coverage, particularly among populations where CAM practices wield substantial influence.

Maternal awareness, acceptability and willingness towards respiratory syncytial virus (RSV) vaccination during pregnancy in Ireland.

BACKGROUND: Respiratory syncytial virus (RSV) is the world's leading cause of viral acute lower respiratory infections (ALRI) in infants. WHO has identified maternal RSV vaccination a priority and candidate vaccines are in development; however, vaccine hesitancy remains an impediment to successful implementation of maternal immunization. This study, the largest antenatal survey conducted to-date, aimed to examine maternal RSV awareness, likely acceptance of RSV vaccination in pregnancy, and attitudes to maternal vaccination. METHODS: Pregnant women of all gestations attending antenatal clinic of a university maternity hospital in Ireland were invited to participate. An information leaflet provided, consent obtained, and survey administered examining RSV awareness, willingness to avail of antenatal RSV vaccination, factors influencing acceptability and preferred sources of assistance. Research Ethics Committee (REC) approval obtained, and general data protection regulation (GDPR) guidelines followed. RESULTS: 528 women completed the survey. A large proportion (75.6%) had never heard of RSV, yet 48.5% would still avail of a vaccine, 45.8% were undecided and only 5.3% would not. The main factor making vaccination acceptable to women (76.4%) was that it protects their infant from illness (p < .001, CV 0.336 for association with acceptance) and general practitioner (GP) was the preferred guidance source in decision-making (57.7%). CONCLUSIONS: Despite low levels of maternal awareness of RSV, pregnant women in Ireland are open to availing of antenatal vaccination. Maternal immunization strategies need to focus on infant's protection from RSV-associated ALRI along with vaccine safety, and build on an interdisciplinary collaboration of maternal, neonatal, primary care and public health services.

Willingness and hesitancy towards the governmental free human papillomavirus vaccination among parents of eligible adolescent girls in Shenzhen, Southern China.

BACKGROUND: Since 2020, China has actively promoted HPV vaccination for eligible adolescent girls through various pilot programmes. This study investigated parental willingness and hesitancy towards the government-sponsored, free human papillomavirus (HPV) vaccination for eligible adolescent girls in Shenzhen, Southern China. METHODS: From June to August 2022, a cross-sectional survey was conducted with parents of girls entering Grade 7, employing an adapted Vaccine Hesitancy Scale to assess vaccine hesitancy and logistic regression to identify factors influencing willingness to accept the free domestic vaccines. RESULTS: Although only 3.4% of the 2856 respondents had their daughters vaccinated against HPV prior to the survey, 91.7% were willing to utilise the governmental vaccination services. Parents with children in public schools (χ2 = 20.08, p < 0.001), those with more secure medical insurance (χ2 = 4.97, p = 0.026), and parents who had received an HPV vaccine themselves (χ2 = 28.829, p < 0.001) showed more reluctance towards the free vaccines. Vaccine hesitancy was presented in a mere 2.1% but was a significant predictor of vaccine refusal, even after adjusting for multiple factors (adjusted OR = 15.98, 95% CI: 9.06, 28.20). Notably, about four-fifths of parents of unvaccinated daughters harboured concerns about the safety and efficacy of the domestic vaccine. CONCLUSIONS: Although parents show a strong inclination to utilise the government vaccination services, their vaccine hesitancy, driven by safety concerns and a preference for imported vaccines, remains a significant barrier for rolling out vaccination coverage. This study highlights the need for multifaceted intervention strategies that address these issues to enhance HPV vaccine uptake effectively.

Understanding the factors associated with COVID-19 vaccine hesitancy in Venezuela.

BACKGROUND: Despite nearly a quarter of Venezuelans remaining unvaccinated against coronavirus disease 2019 (COVID-19), the factors contributing to vaccine hesitancy in the country have not been thoroughly investigated. METHODS: A cross-sectional study was conducted from October 15th to 30th, 2022, using a knowledge, attitudes, and practices (KAP) survey to identify factors associated with COVID-19 vaccine hesitancy. RESULTS: The study analyzed data from 1,930 participants from all 24 states of Venezuela. The majority (93.4%) were vaccinated. The mean age was 40 years, predominantly female (67.3%), and held a university degree (70.6%). The mean KAP score was significantly higher among vaccinated individuals compared to unvaccinated ones (7.79 vs. 3.94 points for knowledge, 40 vs. 24 points for attitudes, and 16 vs. 10 points for practices, all p < 0.001). Increases in the scores for KAP were associated with increased odds of being vaccinated (84.6%, 25.6%, and 33% respectively for each one-point increase, all p < 0.001). Certain demographic factors such as marital status, occupation, religious beliefs, monthly income, and location influence COVID-19 vaccine knowledge. Higher income and certain occupations decrease the odds of low knowledge, while residing in specific states increases it. Attitudes towards the COVID-19 vaccine are influenced by age, health status, vaccination status, and location. Higher income and absence of certain health conditions decrease the odds of negative attitudes. Lastly, age, occupation, monthly income, and location affect vaccine practices. Advanced age and higher income decrease the odds of inappropriate practices, while residing in La Guaira state increases them. CONCLUSION: Factors such as age, education level, occupation, monthly income, and location were found to be associated with knowledge and attitudes towards COVID-19 vaccine among the surveyed Venezuelans.

Adherence to Covid-19 vaccination during the pandemic: the influence of fake news.

OBJECTIVES: to understand how fake news has influenced adherence to Covid-19 immunization, from the perspective of health professionals. METHODS: a qualitative, descriptive-exploratory study was conducted in Campo Grande - MS. Twenty nursing professionals working in vaccine rooms or managing immunobiologicals participated through semi-structured interviews. The interviews were audio-recorded, fully transcribed, and subjected to thematic content analysis. RESULTS: two categories emerged in which the professionals highlighted an increase in vaccine hesitancy among the population, influenced by fake news and denialist actions, which negatively interfered with the population's trust in vaccines and in the professionals administering them. FINAL CONSIDERATIONS: concerns about vaccine safety and denialist actions by authorities and media outlets can contribute to the phenomenon of non-vaccination. The valorization of science, the promotion of educational actions, and raising public awareness about immunization were presented as strategies to increase vaccine coverage.

Meaningful Media Experiences and Vaccination Message Communication: An Experimental Study with Vaccine-Hesitant Individuals.

Guided by the eudaimonic media and the health persuasion literature, the current study explores how meaningful emotions elicited from entertainment media exposure decreases anti-vaccination attitudes among vaccine-hesitant individuals. Results of a between-subjects experiment (N = 409) showed that participants who viewed meaningful music videos (vs. neutral videos) and vaccination messages embedded in the user-generated comments reported more empathy, less reactance, and less anti-vaccination attitudes. Multigroup analysis revealed that this association was held for participants who were hesitant about whether they would get fully vaccinated, but not for participants who were determined to not get vaccinated. Theoretical and practical implications were discussed.

Corona virus vaccine hesitancy among higher education students in Adama City, Oromia, Ethiopia.

Background: Vaccination stands as the most efficient approach for managing the continued transmission of infections and preventing the emergence of novel variants. Coronavirus disease 2019 (COVID-19) vaccine hesitancy poses a significant burden in the fight to achieve herd immunity. Methods: A cross-sectional study, based on institutional parameters, was conducted among a cohort of 530 higher education students, selected via a simple random sampling method. Study participants were selected using a systematic random sampling technique from February to March 2022. Structured questionnaire data were gathered and subsequently analyzed using SPSS version 21. The strength of the association between various factors and COVID-19 vaccine hesitancy was assessed using the odds ratio along with its 95% confidence interval. Statistical significance was deemed to be present at a p-value of < 0.05. Result: The prevalence of coronavirus vaccine hesitancy was 47.5%. The factors that were found to be significantly associated with COVID-19 vaccine hesitancy were residential address (AOR = 2.398, 95% CI: 1.476-3.896); agreeing with leaders and groups that do not support COVID-19 vaccination (AOR = 2.292, 95% CI: 1.418-3.704); coming from a community whose leaders support COVID-19 vaccination for young adults (AOR = 0.598, 95% CI: 0.381-0.940), and believing that COVID-19 vaccines are safe (AOR = 0.343,95% CI: 0.168-0.701). Conclusion: Approximately five out of 10 students who participated in this study were hesitant to get vaccinated against coronavirus. Incorporating messages and initiatives into local plans to specifically target the factors identified in this study is imperative for substantially increasing the COVID-19 vaccine uptake among students in higher education institutions.

Evaluating COVID-19 vaccine acceptance among parents in Saudi Arabia: a systematic review examining attitudes, hesitancy, and intentions.

Introduction: The COVID-19 pandemic, affecting adults and children equally, has caused significant disruption to countries worldwide, including Saudi Arabia. In Saudi Arabia, the fast preventative measures and mass vaccine enrollment were vital to contain the devastating impact of the pandemic. However, vaccine hesitancy, especially among parents toward vaccinating their children, was a significant obstacle to vaccine uptake. Methods: This systematic review followed PRISMA guidelines to assess parental willingness to vaccinate their children against COVID-19, determine the key determinants influencing such intention and attitudes, and underline the significant concerns and misconceptions regarding the vaccine among parents. The Joanne Briggs Institute (JBI) checklist for prevalence studies was used to assess included studies for risk of bias. Results: Twenty-three studies were included in this systematic review, representing a total of 20,926 participants, with over 66% of them were female. Over 37% of the participants were willing to vaccinate their children against COVID-19. Parents' age, gender, level of education, and income were the main determinants of their intention to vaccinate their children. The parents' main concerns were the potential vaccine side effects, safety, and efficacy. Major misconceptions about the COVID-19 vaccine included it being dangerous to children and that children are at lower risk of severe infection; hence, vaccines were not needed. Discussion: This seminal review provides insights to public health policymakers, which should be considered and taken together in light of other studies addressing parental vaccine hesitancy.

Risk perception and trust in the relationship between knowledge and HPV vaccine hesitancy among female university students in China: a cross-sectional study.

BACKGROUND: Cervical cancer poses a heavy health burden in China, with the second highest incidence and mortality rate among female tumors, yet human papillomavirus (HPV) vaccination rate among female university students remain remains low. This study conducted a cross-sectional survey to assess the degree of HPV vaccine hesitancy among female university students and to explore the potential association between knowledge, risk perception, trust, and HPV vaccine hesitancy. METHODS: A total of 1,438 female university students from four Chinese cities were recruited through stratified, multistage, cluster sampling method. The mediation model was constructed using the Bootstrap method, introducing trust and risk perception as mediating variables to examine the effect of knowledge on HPV vaccine hesitancy. RESULTS: The study found that 8.9% (95%CI:7.4%∼10.4%) of the female university students exhibited HPV vaccine hesitancy. Pearson's correlation analysis revealed a negative association between vaccine hesitancy and knowledge, risk perception, and trust. The mediation model showed that knowledge had significant indirect effects on HPV vaccine hesitancy through trust (indirect effect: -0.224, 95% CI: -0.293 ∼ -0.167) and risk perception (indirect effect: -0.013, 95% CI: -0.033 ∼ -0.002). CONCLUSION: HPV vaccine hesitancy among female university students has mitigated, but still needs to be addressed. In addition, trust and risk perception are mediators mediating the relationship between knowledge with HPV vaccine hesitancy. Therefore, there is a need to strengthen public health education to improve knowledge, with a particular focus on providing information about trust and risk perception to reduce HPV vaccine hesitancy.

[Childhood vaccine hesitancy and COVID-19: an analysis based on the perception of health professionals]. / Hesitação vacinal infantil e COVID-19: uma análise a partir da percepção dos profissionais de saúde.

This article presents the results of a study on health professionals' perceptions of childhood vaccine hesitancy related to COVID-19. Based on the theoretical construct of vaccine hesitancy, a qualitative study was conducted with 86 primary health care (PHC) workers in four municipalities in four Brazilian states and in the Federal District. A thematic analysis was performed and three categories were obtained: fear, misinformation about vaccines, and the role of health professionals. Fear as a reason for vaccine hesitancy has led to reflections on the Brazilian Federal Government's management of the pandemic, especially regarding governability and the consequences of the use of digital platforms on the population. Fear was related to the vaccine still being perceived as experimental; to the adverse reactions it may cause; to the lack of long-term studies; to the false perception of reduced risk of COVID-19 in children; and to the Federal Government's behavior, which creates uncertainty about the effects of the vaccine. Vaccine misinformation was related to fake news about the vaccine and its reactions; the phenomenon of infodemic and misinformation; and the lack of guidance and knowledge about vaccines. Finally, the article discusses the fundamental role of PHC workers in increasing vaccination coverage due to the trust among the population and proximity to the territories, factors that enable the reversal of fear and misinformation about vaccines. Throughout the study, authors' sought to show the convergences between the content of the themes outlined and the determinants of vaccine hesitancy and to consider possibilities for rebuilding high adherence to childhood vaccines.

Este artigo apresenta os resultados de uma pesquisa sobre a percepção dos profissionais de saúde sobre a hesitação vacinal infantil relacionada à COVID-19. Baseado no constructo teórico da hesitação vacinal, foi realizada uma pesquisa qualitativa com 86 trabalhadores da atenção primária à saúde (APS) em quatro municípios de quatro estados brasileiros e no Distrito Federal. A análise temática foi realizada e obtiveram-se três categorias: medo, desinformação em vacina e papel dos profissionais de saúde. O medo como motivo de hesitação vacinal gerou reflexões sobre a condução da pandemia pelo Governo Federal, principalmente no que tange à governabilidade por meio desse afeto, e sobre as consequências do uso das plataformas digitais na população. O medo relacionou-se ao fato de a vacina ainda ser percebida como experimental; às possíveis reações adversas; à ausência de estudos de longo prazo; à falsa percepção de risco reduzido da COVID-19 em crianças; e às condutas do Governo Federal geradoras de insegurança nos efeitos da vacina. A desinformação em vacina relacionou-se às fake news sobre a vacina e suas reações; ao fenômeno da infodemia e desinformação; e à ausência de orientação e conhecimento sobre vacinas. Por fim, o trabalho discute o papel fundamental dos profissionais de saúde da APS no aumento da cobertura vacinal devido à confiabilidade perante a população e à proximidade com os territórios, fatores que possibilitam reverter o medo e a desinformação diante das vacinas. Ao longo do trabalho, buscou-se apresentar as convergências entre o conteúdo dos temas delineados e os determinantes da hesitação vacinal e refletir sobre possibilidades para a reconstrução da alta adesão às vacinas infantis.

Este artículo presenta los resultados de una encuesta sobre la percepción de los profesionales de la salud acerca de la reticencia vacunal infantil relacionada con la COVID-19. Con base en el constructo teórico de la reticencia vacunal, se realizó una encuesta cualitativa con 86 trabajadores de la atención primaria de salud (APS) en 4 municipios de 4 estados brasileños y en el Distrito Federal. Se realizó un análisis temático y se obtuvieron tres categorías: miedo, desinformación sobre vacunas y papel de los profesionales de la salud. El miedo como motivo de reticencia vacunal dio lugar a reflexiones sobre el manejo de la pandemia por parte del Gobierno Federal, sobre todo en lo que respecta a la gobernabilidad por medio de esta afección y las consecuencias del uso de plataformas digitales en la población. El temor se relacionó con el hecho de que la vacuna todavía se percibe como experimental; con las reacciones adversas que puedan provocar; con la ausencia de estudios a largo plazo; con la falsa percepción de riesgo reducido de COVID-19 en niños y con las conductas del Gobierno Federal que generan inseguridad sobre los efectos de la vacuna. La desinformación sobre las vacunas se relacionó con noticias falsas sobre la vacuna y sus reacciones; el fenómeno de la infodemia y la desinformación; y la ausencia de orientación y conocimiento sobre las vacunas. Finalmente, el trabajo discute el papel fundamental de los profesionales de la salud de la APS en el aumento de la cobertura vacunal debido a su confiabilidad entre la población y cercanía a los territorios, factores que permiten revertir el miedo y la desinformación respecto a las vacunas. A lo largo del trabajo, se buscó presentar las convergencias entre el contenido de los temas delineados y los determinantes de la reticencia vacunal y reflexionar sobre las posibilidades para la reconstrucción de una alta adhesión a las vacunas infantiles.

A community-engaged approach to translate a Vaccine Hesitancy Scale into Haitian Creole.

OBJECTIVE: Accurately translated health materials are needed to achieve equity in vaccine uptake among U.S. individuals with non-English language preferences. Verbatim translations may not capture the cultural and linguistic vernacular required to understand vaccine hesitancy. We leveraged a community-engaged approach to translate the Vaccine Hesitancy Scale (VHS) into Haitian Creole. METHODS: Following the "WHO Guidelines on Translation and Adaptation of Instruments" and a community-engaged framework, a validated 10-question Vaccine Hesitancy Scale (VHS) underwent forward translation, expert panel review, back translation, and focus group pilot testing. RESULTS: Haitian Creole-speaking translators included two community leaders, one community partner, one study team member, and 13 Haitian, greater Boston-based community members who participated in a focus group to pretest the survey. After four iterations, a linguistic and cultural translation of the VHS was created. CONCLUSION: A community-engaged framework strengthened community partnerships and resulted in a culturally relevant Haitian Creole vaccine hesitancy scale.

Last-mile delivery increases vaccine uptake in Sierra Leone.

Less than 30% of people in Africa received a dose of the COVID-19 vaccine even 18 months after vaccine development1. Here, motivated by the observation that residents of remote, rural areas of Sierra Leone faced severe access difficulties2, we conducted an intervention with last-mile delivery of doses and health professionals to the most inaccessible areas, along with community mobilization. A cluster randomized controlled trial in 150 communities showed that this intervention with mobile vaccination teams increased the immunization rate by about 26 percentage points within 48-72 h. Moreover, auxiliary populations visited our community vaccination points, which more than doubled the number of inoculations administered. The additional people vaccinated per intervention site translated to an implementation cost of US $33 per person vaccinated. Transportation to reach remote villages accounted for a large share of total intervention costs. Therefore, bundling multiple maternal and child health interventions in the same visit would further reduce costs per person treated. Current research on vaccine delivery maintains a large focus on individual behavioural issues such as hesitancy. Our study demonstrates that prioritizing mobile services to overcome access difficulties faced by remote populations in developing countries can generate increased returns in terms of uptake of health services3.

From Cotton Mather to Dr Fauci: Historical Markers of Vaccine Hesitancy.

Vaccine hesitancy became an important topic in the public discourse and academic research during the COVID-19 pandemic, but its history is as long as the history of immunization. One can find the same determinants of vaccine hesitancy, though in variable proportions, since the 1721 Boston smallpox epidemic. We aim to describe several historical immunization moments and analyze them using the vaccine hesitancy framework of the "5Cs" (ie, confidence, complacency, constraints, risk calculation, and collective responsibility).
