Even if all people are vaccinated against the coronavirus, its pandemic may not be stopped. The culprit will be mice that are infected with the coronavirus. This opinion was expressed by biologist Ancha Baranova, a professor at the School of Systems Biology at George Mason University.

"Now humans can infect mice, and vice versa. And that is really bad news. In the presence of natural reservoirs, we cannot say that the virus will disappear when we vaccinate everyone [against COVID-19]," Baranova told Lenta.ru.

According to her, people cannot completely get rid of the mouse population by starting an ecological war. Therefore, it is necessary to look at the natural reservoirs of the virus and see what mutations will come about in mammals during COVID-19. If the virus begins to gradually lose its ability to bind to human receptors, it is possible that "everything is not so bad," the biologist said.
