“…Our study shows that the hesitancy decreased with increased knowledge about the COVID-19 vaccine and its associated processes. Thus, the vaccine-related knowledge, which creates awareness regarding vaccine’s role in decreasing the risks of the diseases among individuals, plays a role in lessening vaccine hesitancy [ 43 ]. Furthermore, being knowledgeable and aware of the vaccine is a significant predictor of vaccine hesitancy in other studies conducted in COVID-19 [ 44 ] and non-COVID-19 [ 45 , 46 ] contexts in lower-middle-income countries like India and Malaysia.…”

Introduction Studies related to the COVID-19 vaccine hesitancy are scanty in Bangladesh, despite the growing necessity of understanding the population behavior related to vaccination. Thus, the present study was conducted to assess the prevalence of the COVID-19 vaccine hesitancy and its associated factors in Bangladesh to fill the knowledge gap. Methods and materials This study adopted a cross-sectional design to collect data from 1497 respondents using online (Google forms) and face-to-face interviews from eight administrative divisions of Bangladesh between 1–7 February 2021. We employed descriptive statistics and multiple logistic regression analysis. Results The prevalence of vaccine hesitancy was 46.2%. The Muslims (aOR = 1.80, p ≤ 0.01) and the respondents living in the city corporation areas (aOR = 2.14, p ≤0.001) had more hesitancy. There was significant variation in vaccine hesitancy by administrative divisions (geographic regions). Compared to the Sylhet division, the participants from Khulna (aOR = 1.31, p ≤0.001) had higher hesitancy. The vaccine hesitancy tended to decrease with increasing knowledge about the vaccine (aOR = 0.88, p≤0.001) and the vaccination process (aOR = 0.91, p ≤ 0.01). On the other hand, hesitancy increased with the increased negative attitudes towards the vaccine (aOR = 1.17, p≤0.001) and conspiracy beliefs towards the COVID-19 vaccine (aOR = 1.04, p≤0.01). The perceived benefits of COVID-19 vaccination (aOR = 0.85, p≤0.001) were negatively associated with hesitancy, while perceived barriers (aOR = 1.16, p ≤0.001) were positively associated. The participants were more hesitant to accept the vaccine from a specific country of origin (India, USA, Europe). Conclusions Our findings warrant that a vigorous behavior change communication campaign should be designed and implemented to demystify negative public attitudes and conspiracy beliefs regarding the COVID-19 Vaccine in Bangladesh. The policymakers should also think about revisiting the policy of the online registration process to receive the COVID-19 vaccine, as online registration is a key structural barrier for many due to the persistent digital divide in the country. Finally, the government should consider the population’s preference regarding vaccines’ country of manufacture to reduce the COVID-19 vaccine hesitancy.

“…Those strategies are already applied in research on other target groups, such as childhood vaccination, HPV in adolescents, and vaccination in the elderly. Effective strategies that could be tested are, among others, education of health care workers for patient communication, evaluated misinformation debunking [ 52 ], and extended knowledge about preventable sequelae [ 53 ]. Also, although vaccine mandate has generated controversy overtime, but have been effective intervention toward population behavior change in some settings; hence, a consideration would be advised, especially for countries with high influenza infection rate with corresponding low vaccination demand [ 54 ].…”

Background Pregnant women are at high risk for severe influenza. However, maternal influenza vaccination uptake in most World Health Organization (WHO) European Region countries remains low, despite the presence of widespread national recommendations. An influenza vaccination reduces influenza-associated morbidity and mortality in pregnancy, as well as providing newborns with protection in their first months. Potential determinants of vaccine hesitancy need to be identified to develop strategies that can increase vaccine acceptance and uptake among pregnant women. The primary objective of the systematic review is to identify the individual determinants of influenza vaccine hesitancy among pregnant women in Europe, and how to overcome the hesitancy. Methods Databases were searched for peer-reviewed qualitative and quantitative studies published between 2009 and 2019 inclusive. Databases included PubMed via MEDLINE, Cochrane Central Register for Controlled Trials, PsycINFO, SAGE Journals, Taylor and Francis and Springer nature. These covered themes including psychology, medicine, and public health. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, 11 studies were eligible and analyzed for significant determinants of influenza vaccine hesitancy among pregnant women in Europe. Results The most commonly reported factors were psychological aspects, for example concerns about safety and risks to mother and child, or general low risk perception of becoming ill from influenza. Doubts about the effectiveness of the vaccine and a lack of knowledge about this topic were further factors. There was also influence of contextual factors, such as healthcare workers not providing adequate knowledge about the influenza vaccine or the pregnant lady stating their antivaccine sentiment. Conclusion Health promotion that specifically increases knowledge among pregnant women about influenza and vaccination is important, supporting a valid risk judgment by the pregnant lady. The development of new information strategies for dialogue between healthcare providers and pregnant women should form part of this strategy.

The vaccine-related knowledge, which creates awareness regarding vaccine’s role in decreasing the risks of the diseases among individuals, plays a role in lessening vaccine hesitancy [37]. Being knowledgeable about the vaccination process has been found in other studies too as a significant predictor of vaccine hesitancy [37,38], leaving ample scopes for vaccine promotion strategies targeting the information gap.…”

IntroductionThe study related to the COVID-19 vaccine hesitancy is scanty in the context of Bangladesh, despite the growing necessity of understanding the mass people’s vaccination-related behavior. Thus, the present study was conducted to assess the prevalence of the COVID-19 vaccine hesitancy and its associated factors in Bangladesh to fill the knowledge gap.MethodologyThis study adopted a cross-sectional study design to collect data from 1497 respondents using online (Google forms) and face-to-face interviews. We employed descriptive statistics and multiple hierarchical linear regression analysis.FindingsThe prevalence of vaccine hesitancy was 41.1%. Men had less hesitancy (β = -0.046, p = 0.030) than women. The Muslims (β = 0.057, p = 0.009) and the respondents living in the city corporation areas (β = 0.132, p <0.001) had more hesitancy. There was significant variation in vaccine hesitancy by administrative divisions (geographic regions). The vaccine hesitancy tended to decrease with increasing knowledge about the vaccine (β = -0.072, p=0.001) and the vaccination process (β= -0.058, p = 0.018). On the other hand, hesitancy increased with the increased negative attitudes towards vaccine (β = 0.291, p <0.001) and conspiracy beliefs towards the COVID-19 vaccine (β = 0.105, p=0.004). The perceived severity of the COVID-19 (β = -0.079, p=0.002) and perceived benefits of COVID-19 vaccination (β = -0.180, p=0.001) were negatively associated with hesitancy, while perceived barriers (β = 0.180, p <0.001) were positively associated. The participants were more hesitant to accept the vaccine from a specific manufacturer.ConclusionThis study emphasizes that negative attitudes and conspiracies towards the COVID-19 vaccine should be reduced through effective communications and contracting with additional vaccine manufacturers should be prioritized. The barriers like online registration for receiving the COVID-19 vaccination need to be removed, and initiatives like text message service using the mobile phone operator can be introduced.HighlightsAbout 41% of the respondents had had hesitancy to accept the COVID-19 vaccine.The hesitancy increased with negative attitudes about vaccines and conspiracy beliefs.Perceived barriers to receive the vaccine were increasing vaccine hesitancy.Perceived severity of the COVID-19 decreased the vaccine hesitancy.Perceived benefits of receiving the COVID-19 vaccine decreased the vaccine hesitancy.
