A Covid vaccine based on virus-like particles will have elements of the S-protein against three variants – the original Wuhan, Delta, and Omicron, Alexander Gintsburg, director of Russia’s Gamaleya Center, said Thursday.
“The vaccine will have at least three different S-protein variants – Wuhan, Delta, and Omicron. So, as a result of vaccination, antibodies of three specific types are to be developed to protect against all possible Omicron variants,” he said.
“This vaccine will be needed amid continuing virus mutations. New variants keep on emerging, but it will be quite easy to introduce new antigen variants into such particles of the vaccine,” Alexander said.
“It will be needed as several Covid variants are circulating in the population concurrently. First, we thought that Omicron would replace Delta by 100 percent. But now it looks like Delta is circulating along with Omicron, depending on the region.”
