"With certain features of the immune system and if it was a severe course of the disease, I can assume that lifelong immunity can be formed," RIA Novosti Maksyutova quotes.
Earlier, the head of the Russian Ministry of Health, Mikhail Murashko, said that people who have developed immunity to coronavirus after a previous infection do not need to be vaccinated this season.
In August, the Gamaleya Center spoke about plans to study secondary immunity to the disease after vaccination.
