The vaccination campaign against COVID-19 may end in Russia by the end of this year, since by that time the population may have formed herd immunity. This is the conclusion reached by Andrey Isaev, the founder and general director of the Scientific Center for Molecular Genetic Research at DNKOM, and quoted by TASS…
“Judging by the data that we see, we already have a fairly high level of herd immunity,” Isaev said. However, according to the expert, this indicator is unstable.
At the same time, Isaev notes that the coronavirus mutates, the immunity accumulated constantly due to vaccination may become irrelevant in relation to new strains, and without revaccination, the level of protection against infection will inevitably fall. Therefore, Isaev believes, humanity cannot yet defeat the coronavirus pandemic once and for all, as happened with the smallpox epidemic.
In addition, the expert suggested that in the future, COVID-19 will mutate and evade antibodies formed after experiments with previous types of strains. The head of DNKOM is not sure that the new strains will be more or less pathogenic, however, he believes, the only conclusion that can already be drawn is that the story with the coronavirus will not end either in 2021 or in 2022.
Earlier it became known that the American pharmaceutical company Pfizer began large-scale trials of a preventive drug against COVID-19. The new antiviral drug is reported to be for early-stage coronavirus treatment or disease prevention.
