Short periods between the introduction of the COVID-19 vaccine can negatively affect the state of human immunity. This was stated by the representative of the European Medicines Agency EMA Marco Cavaleri.
As the official of the European regulator noted, the proposals to introduce booster doses of the vaccine in short periods of four months, if implemented in practice, are fraught with problems with the immune response organism. One should not overload the immune system with frequent revaccinations, Cavaleri summed up, writes Fortune.
The official also stressed that the regulator does not yet have full information about the need for a fourth dose of the vaccine. But primary vaccination, according to Cavaleri, is showing excellent results in terms of preventing the spread of the new coronavirus infection.
