“We have not only those mechanisms that allow us to produce a high level of antibodies, but also mechanisms that control this level of antibodies, and therefore if a person has a high level of antibodies, and he also injects himself with an additional antigen in the form of a vaccine, raise, then the level of antibodies rises slightly, ”TASS quoted him as saying.
According to him, "a person will not cause any harm to himself, but at the same time he may not receive additional benefits, and he will have the same high level of antibodies that he had before the revaccination, if it was high."
Gunzburg noted that six months is the optimal period before revaccination, since this is the minimum period at which the previously produced antibodies are kept at a high level, which provides protection.
Earlier, Gunzburg said that the QR code system introduced in the regions of Russia to improve the coronavirus situation should exist until the level of herd immunity in the country reaches at least 80%.
