While COVID-19 continues raging worldwide, effective vaccines are highly anticipated. However, vaccine hesitancy is widespread. Survey results on uptake intentions vary and continue to change. This review compared trends and synthesized findings in vaccination receptivity over time across US and international polls, assessing survey design influences and evaluating context to inform policies and practices. Data sources included academic literature (PubMed, Embase, and PsycINFO following PRISMA guidelines), news and official reports published by 20 October 2020. Two researchers independently screened potential peer-reviewed articles and syndicated polls for eligibility; 126 studies and surveys were selected. Declining vaccine acceptance (from >70% in March to <50% in October) with demographic, socioeconomic, and partisan divides was observed. Perceived risk, concerns over vaccine safety and effectiveness, doctors’ recommendations, and inoculation history were common factors. Impacts of regional infection rates, gender, and personal COVID-19 experience were inconclusive. Unique COVID-19 factors included political party orientation, doubts toward expedited development/approval process, and perceived political interference. Many receptive participants preferred to wait until others have taken the vaccine; mandates could increase resistance. Survey wording and answer options showed influence on responses. To achieve herd immunity, communication campaigns are immediately needed, focusing on transparency and restoring trust in health authorities.

Abstract Background: Widespread vaccine acceptance is key to achieving herd immunity through vaccination against COVID19, especially because the available vaccines do not have 100% efficacy. The continued infection amongst the unvaccinated can lead to heightened risk of further virus mutation, exposing even those vaccinated to new virus strains. Therefore, there are social benefits in minimising vaccine hesitancy. The objective of this study is to assess the level of COVID19 vaccine hesitancy in South Africa, identify the socio-economic patterns in vaccine hesitancy and to develop a targeted health communication strategy based on the HBM and EPPM models in order to improve vaccine acceptance. Methods: The study uses the nationally representative National Income Dynamics Study - Coronavirus Rapid Mobile Survey (NIDS-CRAM) survey. The analysis combines univariate and bivariate statistics together with multivariate regression models like binomial/ordinal logit and seemingly unrelated regressions.Results: The study finds that vaccine acceptance is lower than that of non-pharmaceutical intervention life face-mask use. Only 55% are fully accepting of the vaccine, while a further 16% are moderately accepting of vaccines. Together, vaccine acceptance is estimated at 70.8% and vaccine hesitancy against COVID19 is estimated at 29.2% amongst the adult South African population. The reasons cited for vaccine hesitancy are primarily due to concerns regarding the side-effects and efficacy of vaccine. the study has identified perceived risk of infection with the mediating role of efficacy as a key predictor of vaccine intention. Apart from vulnerability to infection, those perceiving higher severity of risk (elderly and those with chronic illness) have lower hesitancy. Higher awareness of COVID19 related information and higher household income are correlated with lower vaccine hesitancy. The non-black African population group has significantly high vaccine hesitancy compared to black Africans. Males on average have lower hesitancy compared to females, and unmarried/unpartnered individuals are found to have higher hesitancy. Conclusions: There are other significant differences across socio-economic and demographic variables in vaccine hesitancy. From a communication perspective, it is imperative to continue risk messaging, hand in hand with clearer information on the efficacy of the vaccines

Abstract Background In the current COVID-19 pandemic, the world has reached an important milestone where vaccinations are discovered and are proven to be effective against SARS-COV-2 infections. Though vaccines against COVID-19 are now available, around the globe there is some hesitancy in getting the vaccine. This hesitancy to get vaccinated against COVID-19 is a complex phenomenon with various factors playing a role. This study aims at understanding the perception and expectations of the people about COVID-19 vaccine and the factors influencing the vaccine acceptance. This information is crucial to challenge vaccine hesitancy and to win the combat against the COVID-19 Pandemic through voluntary vaccine efforts. Methods A cross-sectional survey among the residents of the UAE to understand the expectations and perception on vaccination against COVID-19. The survey was conducted online, and the survey design included participant samples to be representative of UAE’s demographics. The results of the survey were analysed with various demographical variables of interest. Results The survey showed that people were more likely to get vaccinated when vaccines are (i) endorsed by trusted government health authorities, (ii) recommended by physicians and family doctors, and (iii) the merits are effectively communicated through government websites and trusted news channels. Availability of vaccines at multiple sites and providing vaccines free of charges are likely to improve the rate of vaccination. The perceptions, expectations and the motivational factors needed for people to get vaccinated differed with age, gender, marital status, income level, and employment status. Conclusion To attain herd immunity against COVID-19, a large proportion of the population needs to be vaccinated and to achieve this the vaccination campaigns should target on specific expectations and motivational factors pertaining to each target group to successfully overcome the challenge of vaccine hesitancy.

Convincing Data

Surveys showed that vaccine hesitancy may influence the acceptance of COVID-19 vaccines in healthcare workers (HCWs) and the general population. Currently, the actual acceptance of COVID-19 vaccination in HCWs has rarely been reported. In the present survey, we investigated the real-world acceptance of COVID-19 vaccination in HCWs in perinatal medicine during the first three-month period of vaccination in China and to identify the main reason for the decline of vaccination. HCWs (1087) who participated in a Chinese national symposium on perinatal medicine during 16–18 April 2021 were invited to answer a 27-question questionnaire online. A total of 1051 HCWs completed the questionnaire. Of them, 86.2% (906/1051) accepted the COVID-19 vaccination and 13.8% (145/1051) declined the vaccination. Because of the vaccine hesitancy, one-fourth of the vaccinated participants did not accept the vaccination until consulted with others or requested by employers. The main reason for the decline of vaccination in 145 unvaccinated HCWs was the concern about vaccine safety. The results indicate that vaccination request by employers may promote vaccine acceptance. More convincing data on the safety of COVID-19 vaccines appears to be important to increase the acceptance of vaccination.

ObjectivesThe management of the COVID-19 pandemic hinges on the approval of safe and effective vaccines but, equally importantly, on high vaccine acceptance among people. To facilitate vaccine acceptance via effective health communication, it is key to understand levels of vaccine scepticism and the demographic, psychological and political predictors. To this end, we examine the levels and predictors of acceptance of an approved COVID-19 vaccine.Design, setting and participantsWe examine the levels and predictors of acceptance of an approved COVID-19 vaccine in large online surveys from eight Western democracies that differ in terms of the severity of the pandemic and their response: Denmark, France, Germany, Hungary, Sweden, Italy, UK and USA (total N=18 231). Survey respondents were quota sampled to match the population margins on age, gender and geographical location for each country. The study was conducted from September 2020 to February 2021, allowing us to assess changes in acceptance and predictors as COVID-19 vaccine programmes were rolled out.Outcome measureThe outcome of the study is self-reported acceptance of a COVID-19 vaccine approved and recommended by health authorities.ResultsThe data reveal large variations in vaccine acceptance that ranges from 83% in Denmark to 47% in France and Hungary. Lack of vaccine acceptance is associated with lack of trust in authorities and scientists, conspiratorial thinking and a lack of concern about COVID-19.ConclusionMost national levels of vaccine acceptance fall below estimates of the required threshold for herd immunity. The results emphasise the long-term importance of building trust in preparations for health emergencies such as the current pandemic. For health communication, the results emphasise the importance of focusing on personal consequences of infections and debunking of myths to guide communication strategies.

Abstract Background Vaccine hesitancy has been a growing challenge for public health in recent decades. Among factors contributing to vaccine hesitancy, concerns regarding vaccine safety and Adverse Events (AEs) play the leading role. Moreover, cognitive biases are critical in connecting such concerns to vaccine hesitancy behaviors, but their role has not been comprehensively studied. In this study, our first objective is to address concerns regarding vaccine AEs to increase vaccine acceptance. Our second objective is to identify the potential cognitive biases connecting vaccine hesitancy concerns to vaccine-hesitant behaviors and identify the mechanism they get triggered in the vaccine decision-making process. Methods First, to mitigate concerns regarding AEs, we quantitatively analyzed the U.S. Vaccine Adverse Event Reporting System (VAERS) from 2011 to 2018 and provided evidence regarding the non-severity of the AEs that can be used as a communicable summary to increase vaccine acceptance. Second, we focused on the vaccination decision-making process. We reviewed cognitive biases and vaccine hesitancy literature to identify the most potential cognitive biases that affect vaccine hesitancy and categorized them adopting the Precaution Adoption Process Model (PAPM). Results Our results show that the top frequent AEs are expected mild reactions like injection site erythema (4.29%), pyrexia (3.66%), and injection site swelling (3.21%). 94.5% of the reports are not serious and the average population-based serious reporting rate over the 8 years was 25.3 reports per 1 million population. We also identified 15 potential cognitive biases that might affect people’s vaccination decision-making and nudge them toward vaccine hesitancy. We categorized these biases based on the factors that trigger them and discussed how they contribute to vaccine hesitancy. Conclusions This paper provided an evidence-based communicable summary of VAERS. As the most trusted sources of vaccine information, health practitioners can use this summary to provide evidence-based vaccine information to vaccine decision-makers (patients/parents) and mitigate concerns over vaccine safety and AEs. In addition, we identified 15 potential cognitive biases that might affect the vaccination decision-making process and nudge people toward vaccine hesitancy. Any plan, intervention, and message to increase vaccination uptake should be modified to decrease the effect of these potential cognitive biases.

Background: The coronavirus disease 2019 (COVID-19) pandemic has caused a large number of deaths along with severe socio-economic effects. The vaccine is considered to be the last hope to control viral transmission. This study aimed to explore the determinants of health care workers’ (HCWs) willingness to take the COVID-19 vaccination.Methods: A structured, pre-validated, and pre-tested questionnaire was administered online to 599 HCWs including physicians, residents, and nurses from different types of healthcare set-ups across India. Information was collected regarding vaccine acceptability, attitude toward vaccination, and reasons for hesitancy. The chi-square test, followed by multinomial regression analysis, was applied to determine the factors associated with HCWs’ vaccination willingness.Results: It was found that 73 % (n=437) of HCWs were willing to accept the vaccines, while 10.85% (n=65) refused and 16.2% (n=96) needed more time to decide. Gender (P<0.001), occupation (P=0.040), working as front-line workers (P=0.008), vaccine manufacturing country preferences (P<0.001), and perceived risk of catching COVID-19 in the next 6 months (P=0.005) had a significant association with intent to receive vaccination (the response were “yes” vs. “no” and “not sure”). The reasons for vaccine hesitancy were vaccine safety and efficacy concerns, antivaccine attitude and beliefs, personal choice, and not wanting to take a vaccine before others.Conclusion: The majority of HCWs agreed to take COVID-19 vaccines once available. Nevertheless, providing support to manage evolving vaccine environments will help change the perception of HCWs who refuse or are reluctant to take the vaccines.

Using Data

To achieve herd immunity against COVID-19, it is crucial to know the drivers of vaccination intention and, thereby, vaccination. As the determinants of vaccination differ across vaccines, target groups and contexts, we investigate COVID-19 vaccination intention using data from university students from three countries, the Netherlands, Belgium and Portugal. We investigate the psychological drivers of vaccination intention using the 5C model as mediator. This model includes five antecedents of vaccination: Confidence, Complacency, Constraints, Calculation and Collective Responsibility. First, we show that the majority of students have a positive propensity toward getting vaccinated against COVID-19, though only 41% of students are completely acceptant. Second, using the 5C model, we show that ‘Confidence’ (β = 0.33, SE = 03, p < .001) and ‘Collective Responsibility’ (β = 0.35, SE = 04, p < .001) are most strongly related to students’ COVID-19 vaccination intention. Using mediation analyses, we show that the perceived risk and effectiveness of the vaccine as well as trust in the government and health authorities indirectly relate to vaccination intention through ‘Confidence’. The perceived risk of COVID-19 for one’s social circle and altruism, the need to belong and psychopathy traits indirectly relate to vaccination intention through ‘Collective Responsibility’. Hence, targeting the psychological characteristics associated with ‘Confidence’ and ‘Collective Responsibility’ can improve the effectiveness of vaccination campaigns among students.

Objectives: Vaccination is the provision of a vaccine to initiate immunity trough stimulating immune system to develop protection from a certain disease. When a sufficiently large proportion of a population has been vaccinated, herd immunity initiated. The effectiveness of vaccination has been widely studied and verified. Although the harsh vaccine safety systems, some parents remain minded regarding the safety of the childhood vaccines and immunization schedule. These hesitations pushed some parents to not allow their children to receive some or all the scheduled vaccines.  The aim of the study is to assess the general population awareness regarding vaccines and to detect prevalence of vaccine hesitancy in Aseer region, southern of Saudi Arabia. Methods: A descriptive cross-sectional approach was used targeting all parents in Aseer region. Data were collected using structured questionnaire which developed by the researchers after intensive literature review and expert’s consultation. The questionnaire data included parents’ socio-demographic data, parents’ awareness regarding child vaccines safety and efficacy, parents’ attitude and adherence to children vaccination and hesitancy towards vaccines. Results: The survey included 796 participants whose ages ranged from 18 to 55 years old. Two thirds (63.4%) of the participants were females. Regarding vaccination adherence and hesitancy among participants, more than three quarters were completely adherent to the child vaccination schedule and only 3.9% were non adherent. As for participants awareness regarding child vaccination safety and efficacy, 89.3% of the respondents agreed on that vaccination keep child healthy, 84.2% reported that child vaccine is safe and effective, 83.4% said that all Saudi scheduled vaccines are effective. Conclusion: In conclusion, the study revealed that vaccine hesitancy among participants was not low and should be considered irrespective of their high awareness level. The recorded antivaccine action was mostly related to vaccines safety not efficacy. Keywords: Vaccine hesitancy, antivaccine movement, parents, awareness, adherence

AbstractBosnia and Herzegovina is among ten countries in the world with the highest mortality rate due to COVID-19 infection. Lack of lockdown, open borders, high mortality rate, no herd immunity, no vaccination plan, and strong domestic anti-vaccination movement present serious COVID-19 concerns in Bosnia and Herzegovina. In such circumstances, we set out to study if the population is willing to receive the vaccine.A cross-sectional study was conducted among 10,471 adults in Bosnia and Herzegovina to assess the attitude of participants toward COVID-19 vaccination. Using a logistic regression model, we assessed the associations of sociodemographic characteristics with vaccine rejection, reasons for vaccine hesitancy, preferred vaccine manufacturer, and information sources.Surprisingly, only 25.7% of respondents indicated they would like to get a COVID-19 vaccine, while 74.3% of respondents were either hesitant or completely rejected vaccination. The vaccine acceptance increased with increasing age, education, and income level. Major motivation of pro-vaccination behaviour was intention to achieve collective immunity (30.1%), while the leading incentive for vaccine refusal was deficiency of clinical data (30.2%). The Pfizer-BioNTech vaccine is shown to be eightfold more preferred vaccine compared to the other manufacturers. For the first time, vaccine acceptance among health care professionals has been reported, where only 39.4% of healthcare professionals expressed willingness to get vaccinated.With the high share of the population unwilling to vaccinate, governmental impotence in securing the vaccines supplies, combined with the lack of any lockdown measures suggests that Bosnia and Herzegovina is unlikely to put COVID-19 pandemic under control in near future.

Abstract Background Vaccine hesitancy is emerging as a significant challenge in many parts of the world in the fight against the COVID19 pandemic. The continued infection amongst the unvaccinated can lead to a heightened risk of further virus mutation, exposing even those vaccinated to new virus strains. Therefore, there are social benefits in minimising vaccine hesitancy. The objective of this study is to assess the level of COVID19 vaccine hesitancy in South Africa, identify the socio-economic patterns in vaccine hesitancy and highlight insights from the national survey that can inform the development of a COVID-19 vaccination acceptance communication campaign. Methods The study uses the nationally representative National Income Dynamics Study - Coronavirus Rapid Mobile Survey (NIDS-CRAM) survey. The analysis combines univariate and bivariate statistics, as well as multivariate regression models like binomial/ordinal and multinomial logit. Results The study finds that vaccine acceptance is lower than that of non-pharmaceutical intervention like face-mask use. Only 55% fully accept the vaccine, while a further 16% are moderately accepting of vaccines. Together, vaccine acceptance is estimated at 70.8%, and vaccine hesitancy against COVID19 is estimated at 29.2% amongst the adult South African population. The study has identified the perceived risk of infection with the mediating role of efficacy as a key predictor of vaccine intention. Higher awareness of COVID19 related information and higher household income are correlated with lower vaccine hesitancy. The non-black African population group has significantly high vaccine hesitancy compared to black Africans. Conclusions There are other significant differences across socio-economic and demographic variables in vaccine hesitancy. From a communication perspective, it is imperative to continue risk messaging, hand in hand with clearer information on the efficacy of the vaccines.
