Immunologist Mikhail Kostinov, in a conversation with Sputnik radio, said that in some cases, revaccination against coronavirus with a double dose is possible.
He noted that usually the first vaccination is carried out in two stages, in revaccination – in one. In this case, it is possible to receive a double dose of the vaccine as a booster.
To do this, you should come to an appointment with a doctor and consult with him about this. In this case, the specialist must take into account the past human diseases, age and individual characteristics.
