Acceptance of a vaccine against COVID-19 – a systematic review of surveys conducted worldwide

Abstract

OBJECTIVES: The most promising strategy for managing COVID-19 pandemic is achieving suffi cient vaccination rate worldwide. The question is how many people will be willing to get vaccinated. STUDY DESIGN: We systematically reviewed peer-reviewed manuscripts monitoring people´s intention to receive a vaccine against COVID-19. METHODS: Up to December 28, 2020 we identifi ed 62 relevant peer-reviewed articles in PubMed, Web of Science, Scopus and GoogleScholar. RESULTS: Total sample size was 118 855 respondents with overall average COVID-19 vaccine acceptance rate of 72.5% which is "just" the level estimated to be suffi cient for reaching herd immunity threshold. Surprisingly, healthcare workers showed smaller interest in receiving the vaccine when compared to general adult population and university students. On the other hand, their attitude to vaccination did not change over time. In case of general adult population, the longer the pandemic lasts, the smaller proportion of population wants to get vaccinated. Vaccination intentions were independent of gross domestic product and human development index. CONCLUSION: Willingness of population to receive COVID-19 is just at the herd immunity threshold and it is decreasing over time (Tab. 2, Fig. 3, Ref. 110).

Willingness and influential factors of parents to vaccinate their children against the COVID-19: a systematic review and meta-analysis

“…The wide range of parents' willingness among studies is confirmed by similar reviews in the general population and could be due to different study designs, study populations, levels of knowledge and information, attitudes towards vaccination etc. (Galanis et al, 2021;Snehota et al, 2021;. Interestingly, we did not find differences in parents' willingness to vaccinate their children according to the continent that studies were conducted.…”

“…We found that the overall proportion of parents that intend to vaccinate their children against the COVID-19 is moderate (56.8%) with a wide range among studies from 29% to 72.7%. Parents' intention to vaccinate their children against the COVID-19 is lower than intention of the general population to take a COVID-19 vaccine (56.8% vs. 73%) (Snehota et al, 2021;. Also, the willingness of high-risk groups such as healthcare workers to accept COVID-19 vaccination is higher than parents' willingness to vaccinate their children (63.5% vs. 56.8%) (Galanis et al, 2020;Luo et al, 2021).…”

“…Several factors influence vaccination intention and uptake in the general population such as socio-demographic characteristics, attitudes towards vaccination, psychological factors, perceptions of risk and susceptibility to COVID-19, knowledge, information, personal factors, medical conditions, etc. (Al-Amer et al, 2021;Galanis et al, 2021;Snehota et al, 2021;Wake, 2021;.…”

“…COVID-19 vaccine uptake relies on adequate production, fair distribution, and high levels of acceptance among the general public (Neumann-Böhme et al, 2020). Recent meta-analyses found that the overall COVID-19 vaccine acceptance rate was approximately 73%, while acceptance among the general population is higher than among healthcare workers (Galanis et al, 2020;Luo et al, 2021;Snehota et al, 2021;. Also, real-world data from early studies reveal that COVID-19 vaccination uptake ranges from 28.6% to 98% in the general population (Galanis et al, 2021).…”

Cross-sectional assessment of predictors for COVID-19 vaccine uptake: an online survey in Greece

“…COVID-19 vaccine acceptance shows a great variability across countries or regions which may affect the efforts to contain the pandemic (Aw et al, 2021). According to meta-analyses (Snehota et al, 2021; Q Wang et al, 2021), the average COVID-19 vaccine acceptance rate in the general population is about 73% which is lower than the percentage estimated to be sufficient for reaching herd immunity threshold with a COVID-19 vaccine that is at least 80% effective (Bartsch et al, 2020). Moreover, the longer the COVID-19 pandemic lasts, the smaller rate of the general population wants to get vaccinated (Snehota et al, 2021).…”
