Abstract
Over the past two years, COVID19 has continued to be a worldwide problem. Largescale vaccination of the population is aimed at achieving herd immunity. The presence of 80 % or more immune people in the population should lead to the end of the pandemic with the least human losses. The purpose of the study: to assess the impact of vaccination on the incidence of COVID19 infection among students of the medical faculty of the Belarusian State Medical University. Information on cases of COVID19 infection among students (total sample N = 351 people) from the beginning of 2020 to December 31, 2021, as well as data on specific prophylaxis with various vaccine options, were obtained. In the group of unvaccinated students, 46,15 % were ill with COVID19 infection; among vaccinated students (n = 249 people), 9,24 % had COVID19 infection after vaccination – as of December 31, 2021. A comparative analysis did not reveal significant differences in efficacy between the two most commonly used vaccines in 2021 in the Republic of Belarus – Sputnik V (GamCOVIDVak) and Vero Cell (Sinopharm). After the achievement of herd immunity (as of November 1, 2021, the pool of conditionally immune students reached 79,20 % of the total sample), only isolated cases of the disease were registered in November and December 2021.
