Vaccination is the most reliable way to protect the population from severe course of COVID -19. By the end of 2021, in the developed countries of the world, a total of at least 77% of the population had already received a full dose of the vaccine. This means that more than 1 billion people around the world are immune to the coronavirus. According to scientific data, antibodies in the blood of people who have had coronavirus can be detected more than a year after infection. Those who had severe COVID-19 had higher antibody titers than those who had only mild symptoms.
Based on the above data, the study of antiviral anti-SARS-CoV-2 antibodies is a very urgent problem for effective organization of anti-epidemic measures aimed at combating COVID-19.
