Scientists update data on how long immunity lasts after COVID-19

According to PNAS , many people who recover from coronavirus develop an immune response to the disease. However, it doesn't last too long.

In particular, scientists from the University of Gothenburg found that after the virus enters the body, it begins to resist the disease. Because of this, virus-specific T cells (lymphocytes that play a central role in the immune response) are activated. However, they are divided into two types. The first - appear in the blood immediately after COVID-19, but disappear after 10-12 weeks, the second - a group of highly specialized T cells designed to facilitate the destruction of infected cells, remain active in the blood for a long time.

Scientists have suggested that it is the second group of cells that protects the body from the repeated severe course of the disease, if the person is still infected with the coronavirus again.

They noted that a number of studies conducted as part of the study of the immune response to coronavirus have already shown that “deep” immunity lasts about 20 months after the disease.

It should be noted that the city authorities on the eve announced an increase in the number of cases of coronavirus in Kiev and recalled that 112 vaccination points are operating in the city, so everyone can come to the nearest Primary Health Care Center or Consultative and Diagnostic Center and do the first, second or booster dose.

Mass vaccination centers also continue to operate in shopping centers, in particular in Gulliver and River Mall, in the Ukraine department store and some others.
