In the future, vaccines will contain 2-3 strains of SARS-CoV-2 at once. This was stated in an interview with Izvestia(Russian site) by the director of the State Research Center for Virology and Biotechnology “Vector”.
“As with influenza, every year or twice a year, a WHO committee will decide to change the composition of vaccines in terms of strains in order to obtain population immunity. And we will change the composition of anti covid vaccines by analogy with influenza vaccines, ”Maksyutov said.
He noted that the use of drugs “built on the basis of current strains” COVID-19 drugs will safely form a collective immunity to the virus.
Maksyutov also said that Vektor is currently testing a three-time vaccine against coronavirus. The drug is planned to be registered in about two months.
Earlier, the head of “Vector” explained the high infectivity of the “delta” strain of SARS-CoV-2.
