The director of the Gamaleya center, Alexander Gintsburg, said that cases of coronavirus in those vaccinated with one component of the Sputnik V drug are rare, and after the introduction of the second – isolated.
Gunzburg said that isolated cases of infection are possible in those who have been vaccinated with the two components, in which “after the second injection, the 21-day period of developing immunity has not been completed.”
Earlier, the center of Gamaleya reported that repeated vaccination with Sputnik V is possible and may be more effective than primary vaccination.
