The break between two doses of the vaccine should not be too sick, otherwise a person who has only gone through the first stage of vaccination will have to do it again. This was stated by the former chief infectious disease specialist in Moscow, virologist Nikolai Malyshev, reports IA DEITA.RU with reference to Ura.ru. There may be a lot of reasons why a citizen may not give the second obligatory injection. For example, a person fell ill after the first time or was ill for too long. After that, you need to consult with your doctor, who will tell you whether you need to put the first dose of the vaccine again. Malyshev recalled that those who fell ill should not go through vaccination. In these cases, the second dose of vaccination can only be given two weeks after recovery. Another virologist, head of the cell proliferation laboratory of the Institute of Molecular Biology, Pyotr Chumakov, also advised Russians not to vaccinate against the background of the disease, however, noted that both doses of the vaccine must be delivered.
