Thus, they refuted the theory of long-term immunity to COVID-19. Scientists also determined that the highest content of antibodies to the virus is fixed in patients three weeks after the onset of the first symptoms.
During this period, 60% of people have a very high level of immunity to coronavirus. But after three months, a strong immunity to infection persists in only 17% of patients.
For three months of research, the number of antibodies in the blood of many subjects fell to insignificant, and some could not at all detect the presence of immunity.
Lead author of the study, Katie Dores, believes that refuting the theory of long-term immunity to coronavirus can have a significant impact on the vaccination process in different countries.
Note that earlier scientists were able to protect monkeys from re-infection with coronavirus.
