If a vaccine against COVID-19 was available, would you like to be vaccinated? And are you vaccinated against flu and other diseases? A survey among university students during state of emergency.

AIM: Achieving sufficient vaccination rate (and herd immunity respectively) is considered to be the most promising strategy for prevention of outbreaks of novel coronavirus disease in future. The main aim of this work was to compare willingness of university students to receive vaccine against COVID-19 with vaccines for adults against other well-known diseases. Another aim was to assess students´ opinion on growing trend of parents refusing to vaccinate children. METHODS: The online questionnaire shared with students consisted of 12 questions. It was distributed via university bulk emails and social media. RESULTS: 3,133 students responded to our questionnaire. Overall university response rate was 15.9%. Students of our university showed significantly much stronger interest in receiving vaccine against COVID-19 than vaccine against other diseases (p < 0.0001). Students also showed strong pro-vaccination attitude to vaccination of children. CONCLUSION: The study showed very well sudden change of attitude of university students to vaccination of adults at the time of strong restrictive regulations. Most of university students had pro-vaccination attitude to vaccination of children.

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

OBJECTIVES: The most promising strategy for managing COVID-19 pandemic is achieving sufficient 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 identified 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 sufficient 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).  Keywords: vaccination, survey, COVID-19, pandemic, review.
