PETROPAVLOVSK-KAMCHATSKIY, Russia (Sputnik) - Alexander Gintsburg, the head of Russia's Gamaleya research centre, which developed Sputnik V, said there is currently no need to modify the vaccine, but modern technologies make it possible to do it within weeks.
"At the moment, those who use Sputnik V definitely do not face the need to change the vaccine strain. Unfortunately, no one will be able to tell you what will happen next with the evolution [of the virus]. Our technologies indeed allow us to create new antigen variants of vaccines very quickly, literally for a couple of weeks," Gintsburg told Rossiya 1.
The health official also confirmed that Sputnik V could be used " an infinite number of times" for bi-annual re-vaccination.
