Associate Professor Voznesensky: revaccination with two-component drugs once every six months is not dangerous 
the consequences of revaccination against coronavirus with two-component drugs. According to him, this procedure is not dangerous, RIA Novosti reports.
The scientist said that revaccination against COVID-19 with two-component drugs once every six months is not dangerous if at the time of vaccination the person has no contraindications to it.
“The most important thing is that the introduction of the vaccine was not earlier than one to two months after the introduction of the previous vaccine. If this deadline is met – and we are talking about six months – then there should be no pitfalls, ”Voznesensky stressed.
Earlier, virologist Konstantin Chumakov called an alarm signal for re-vaccination against COVID-19. According to him, if the level of antibodies to coronavirus has dropped noticeably, then you should hurry up and get vaccinated again. However, a high level of antibodies will only increase with revaccination.
