“Almost 600 thousand Muscovites have already been vaccinated,” he wrote on his blog.

Sobyanin also spoke about the start in the capital of an epidemiological study of immunity stability after vaccination against coronavirus.

“2 thousand people who received the first component of the vaccine three to six months ago will take an antibody test every month (from February to August),” he said.

According to Sobyanin, in this way it will be possible to assess the dynamics of changes in antibodies in each of the study participants 9-12 months after vaccination and the need for re-vaccination against COVID-19 before the autumn-winter season.

Earlier it was reported that about 175 thousand Moscow residents over 60 years old received a coronavirus vaccine.
