Social norms, vaccine confidence, and interpersonal communication as predictors of vaccination intentions: Findings from slum areas in Varanasi, India

In recent years, India has seen significant improvements in childhood immunization, but rates among the urban poor remain stagnant. Disruptions during COVID-19 pandemic have created further challenges. This paper focuses on how social norms, vaccine confidence, and interpersonal communication independently and jointly affect vaccine intentions among caregivers of infants living in six slum areas in Varanasi, India. Data for this study come from the baseline assessments conducted before implementing the Happy Baby Program, an intervention to improve vaccination attitudes and intentions. In-person interviews (N = 2,058) were conducted with caretakers of children up to two years old. Analyses showed that interpersonal communication about vaccines, descriptive norms, injunctive norms, and vaccine confidence were each associated with intentions to vaccinate in both a bivariate and, except for injunctive norms, a multivariate model. In addition, we found significant interactions among these variables, suggesting that the roles of interpersonal communication and vaccine confidence attenuated the relationship between social norms and vaccination intention. Overall, our model explained 46.2 % of the variance in vaccine intention. Given the strengths of the relationships observed in this study, intervention strategies should focus on enhancing social norms and vaccine confidence to promote vaccination.

Predicting COVID-19 and Influenza Vaccination Confidence and Uptake in the United States.

This study investigates and compares the predictors of COVID-19 and influenza vaccination confidence and uptake in the U.S. Vaccine hesitancy is defined as the reluctance or refusal (i.e., less than 100% behavioral intention) to vaccinate despite the availability of effective and safe vaccines. Vaccine hesitancy is a major obstacle in the fight against infectious diseases such as COVID-19 and influenza. Predictors of vaccination intention are identified using the reasoned action approach and the integrated behavioral model. Data from two national samples (N = 1131 for COVID-19 and N = 1126 for influenza) were collected from U.S. Qualtrics panels. Tobit regression models were estimated to predict percentage increases in vaccination intention (i.e., confidence) and the probability of vaccination uptake (i.e., intention reaching 100%). The results provided evidence for the reasoned approach and the IBM model and showed that the predictors followed different patterns for COVID-19 and influenza. The implications for intervention strategies and message designs were discussed.

Attitudes towards Monkeypox vaccination and predictors of vaccination intentions among the US general public.

Amidst an unprecedented Monkeypox outbreak, we aimed to measure knowledge, attitudes, practices and Monkeypox vaccination intentions among the U.S. adult population. We conducted an online cross-sectional survey, representative of the U.S. adult general public in June 2022. We asked participants whether they would receive a Monkeypox vaccine, if they were recommended to do so. Participants also answered questions on their self-assessed level of Monkeypox knowledge, risk perception, perceived exaggeration of the threat, and self-efficacy around Monkeypox. Furthermore, we asked about their trusted sources of information, COVID-19 vaccination status and administered the 6-item Vaccine Trust Indicator (VTI). Survey weights were created based on age, gender and race. We analyzed predictors of Monkeypox vaccination intentions using logistic regression, adjusted for education, age, race and ethnicity. A total of 856 respondents completed the survey, of which 51% (n = 436) were female and 41% (n = 348) had a college degree or higher. If recommended, 46% of respondents intended to get vaccinated against Monkeypox, 29% would not get vaccinated and 25% did not know. Almost half the respondents (47%) found their own knowledge level about Monkeypox poor or very poor. The most trusted sources of information about the outbreak were healthcare professionals and officials, but also known doctors and researchers with a large online following. Only 24% indicated that the U.S. Centers for Disease Control and Prevention should be in charge of the outbreak response. Being vaccinated against COVID-19 was a strong predictor of intention to receive a Monkeypox if recommended (adjusted Odds Ratio (aOR) 29.2, 95% Confidence Interval (CI) 13.1-65.3). Increased risk perception was positively associated with vaccination intentions (aOR 2.6, 95% CI 1.8-3.6), scoring high on the VTI as well (5.4, 95% CI (3.2-9.1). The low levels of self-assessed knowledge, vaccination intentions and influence of COVID-19 vaccination status point to a lack of clear communication.

Caregivers’ Willingness to Vaccinate Their Children against Childhood Diseases and Human Papillomavirus: A Cross-Sectional Study on Vaccine Hesitancy in Malawi

Background: Vaccines are among the most effective and cost-efficient public health interventions for promoting child health. However, uptake is considerably affected by vaccine hesitancy. An example is Malawi, with a decline in second vaccine doses and the highest cervical cancer incidence and mortality rate in Sub-Saharan Africa. Understanding vaccine hesitancy is especially important when new vaccines are introduced. This study explores factors contributing to vaccine hesitancy for routine childhood immunization and the human papillomavirus vaccine in Malawi. Methods: The study used a cross-sectional survey design targeting caregivers of children under five years old and adolescent girls. The sample population was derived using three inclusion criteria: one district with low vaccine uptake (Dowa), one district with high vaccine uptake (Salima), and one district where human papillomavirus vaccine was piloted earlier (Zomba). A convenience sample of one primary and one secondary health facility was selected within each district, and participants were systematically included (n = 600). The measures were based on 5C scale for measuring vaccine hesitancy. Multiple regression analyses were performed to explore vaccination intention predictors. Results: Confidence in vaccine safety was the strongest predictor of routine childhood immunization, followed by constraints due to everyday stress. Caregivers had lower confidence in vaccine safety and efficacy when they believed rumors and misinformation and were unemployed. Confidence was higher for those who had more trust in healthcare workers. Age, gender, religion, education, employment, belief in rumors, and trust in healthcare workers were considered predictors of vaccination intention. A husband’s positive attitude (approval) increased childhood vaccination intention. For human papillomavirus, vaccination intentions were higher for those with lower education, more trust in healthcare workers, lower complacency, and a lower tendency toward calculating the benefits and risks of vaccination. Knowledge of human papillomavirus did not increase vaccination intention, but the need to attain a husband’s approval did. Being a young adult and unemployed increased belief in rumors, while trust in healthcare workers reduced the belief. Conclusions: This study provides good insights into the drivers of vaccine hesitancy across different contexts in Malawi. However, further studies are necessary to understand low risk perception among elderly people and the declining trend in second vaccine doses.

Predicting and understanding seasonal influenza vaccination behaviour among forensic mental health inpatients

Objectives This study aimed to identify demographic and psychological predictors of seasonal influenza vaccination intentions and behaviour among a sample of inpatients in a secure forensic mental health service. It also sought to explore patient experiences about being offered the vaccine. Design This study used a mixed-methods design. The quantitative element employed a prospective design using a questionnaire; both cross-sectional and prospective findings are reported. For the qualitative part of the study, semi-structured interviews were conducted and analysed using Interpretative Phenomenological Analysis (IPA). Main outcome measures Seasonal influenza vaccination intentions and behaviour Results Past behaviour, vaccine knowledge and cues to action were predictors of vaccination intention (N = 57). Cues to action remained as the only statistical predictor of vaccination behaviour (N = 55). Nine interviews were conducted with four vaccinated and five unvaccinated participants. Three main themes were formed in the IPA analysis; these were ‘Managing Decisional Conflict’, ‘Interaction with Immune Function’ and ‘The Role of Others’. Conclusions The results highlighted the integral role of health professionals in shaping patient’s vaccination behaviour within a secure mental health setting. Recommendations for vaccination promotion strategies were offered.

MenACWY vaccination decisions in the Netherlands: the role of risk perceptions

Abstract Background The Netherlands experiences an unprecedented increase in meningococcal W infections. A national catch-up menACWY vaccination campaign started in October 2018, covering birth cohorts 2001-2005. To understand menACWY vaccination decisions, our study reports on perceptions of risks and their influence on menACWY vaccination intentions during an ongoing outbreak of meningococcal infections. Methods Online surveys were administered in September 2018 among adolescents (AD) targeted for menACWY vaccination (N = 3036) and parents (PA) of these adolescents (N = 3002). Following a mental models approach, survey items addressed knowledge and beliefs of meningococcal disease, the menACWY vaccination and vaccinations in general, and menACWY vaccination intention. Random Forest Analyses were conducted to identify those knowledge and beliefs that strongest predict vaccination intention. Results The response was 52.8% (N = 1603) in AD and 57.1% (N = 1784) in PA. 71% Of AD and 83% of PA indicated a positive vaccination intention. Most respondents perceived meningococcal disease as a severe disease with possible deathly consequences and were aware of transmission routes. Some misbeliefs of vaccines were rather strongly represented, with respectively 35% of AD and 45% of PA thinking that each year a number of children dies due to vaccination side effects. Preliminary results indicate that perceptions of vaccines in general, especially concerning the need for and the effectiveness, were the strongest predictors of vaccination intention in both AD and PA. Conclusions Adolescents and their parents seemed well informed about meningococcal disease, but less about vaccinations. The belief that vaccines are needed and effective in preventing infectious diseases seems to be of more importance in vaccination decisions than other beliefs of disease and vaccination. Future communications need to address the identified misbeliefs and emphasize the need for and effectiveness of vaccines. Key messages MenACWY vaccination intentions are more dependent on beliefs about vaccines in general than on beliefs about meningococcal disease and the menACWY vaccination. The belief that vaccines are needed and effective in preventing infectious diseases is of major importance in menACWY vaccination decisions.

A study on the predictors of Korean male students' intention to receive human papillomavirus vaccination.

The objective was to survey the current state of human papillomavirus (HPV) vaccination and the predictors of vaccination intention among Korean male students of high school (ages 15-19) and university (ages 17-27). Human papillomavirus is a sexually transmitted infectious agent causing uterine cervical, anal, and/or penile cancer and genital warts in males and females. Infection rate of human papillomavirus increases from the age when sexual intercourse first occurs. Therefore, motivation to receive human papillomavirus vaccination is needed to protect infection. Cross-sectional descriptive survey was performed only in male students. They are less aware of human papillomavirus than females, because human papillomavirus vaccination has been targeted on females for preventing cervical cancer in Korea. Data were collected using a self-reporting questionnaire for male high school and university students sampled from a city in Korea. Human papillomavirus vaccine-related knowledge, health beliefs, demographic, and sexual history information variables relating to intentions to vaccinate were assessed. The human papillomavirus vaccination rate was very low and the levels of knowledge and health beliefs were low. The significant predictors that raised the intention of human papillomavirus vaccination were a university student, experience of sexual intercourse and perceiving the benefits of human papillomavirus vaccination. To promote human papillomavirus vaccination, educational programming targeting males should include health beliefs and knowledge, emphasising that vaccination is important to prevent uterine cervical cancer and to role as a preventative measure against common male diseases. Male high school students should be included as a major target population for school human papillomavirus education programmes, as they are at the age of commencing sexual intercourse. In addition, public health policies including human papillomavirus vaccination in the national immunisation programme are warranted.
