The vaccine against COVID-19, the duration of protection of which will remain 5-10 years, depends on the strains of the virus that are to be encountered, the director of the Gamaleya National Research Center for Epidemiology and Microbiology Alexander Gintsburg is sure.
“The validity period of Sputnik V against those strains of the Wuhan and subsequent variants, we very much hoped that there would be more than one year, and maybe not two years. And much longer. Because memory cells seem to persist for a very long time. But the strain has changed so that it has escaped the attack, which can be organized by antibodies that are synthesized by memory cells. Therefore, this vaccine now has to be administered once every six months, “the specialist explained the timing of the protective effect of the vaccine in an interview with”RIA News” November 22 .
Gunzburg added that subsequent vaccine development depends on the evolution of pathogens that will have to be dealt with with vaccines.
Earlier, a Japanese geneticist announced the self-destruction of the Delta strain, which could not copy itself due to errors in the genome and ceased to exist. This is how the scientist explained the sharp decline in cases of the disease in the country after three months of record rates.
A large-scale vaccination has been taking place in Russia since January. Citizens are vaccinated free of charge and voluntarily. Five vaccines against coronavirus have been registered in the country: Sputnik V, which became the first vaccine against COVID-19 in the Russian Federation and the world, as well as Sputnik Light, EpiVacCorona, EpiVacCorona-N and KoviVak.
