Gunzburg allowed a vaccine change with a COVID-19 mutation in a couple of weeks

New vaccine options will have to be developed when a new strain of COVID-19 appearswith a dramatically altered S-protein sequence, the specialist noted

Center them. Gamalei, who developed Sputnik V, is ready to create new vaccine options if existing drugs cannot provide the required amount of antibodies against new strains of COVID-19. This was stated by the director of the center Alexander Gintsburg in an interview with the Russia 1 TV channel.

He noted that if a new strain of coronavirus appears with a dramatically altered S-protein sequence, then new vaccine options will probably have to be used in the fight against infection.

“If the vector technology is registered, then we can really respond to newly emerging threats within weeks,” he added.

According to the specialist, those who were vaccinated with Sputnik V have antibodies that have a greater neutralizing activity than those who have been ill.

Sputnik V is a combined vector vaccine. It was developed at the National Research Center for Epidemiology and Microbiology. N.F. Gamaleya. Later, the center also released the Sputnik Light vaccine, which is the first component of Sputnik V.

The principle of operation of the vector vaccine is as follows. The vaccine uses a safe virus that delivers specific proteins of the respective microorganism, which causes an immune response, but the person does not get sick. The deactivated virus is coded to form certain parts of the corresponding pathogen. The virus becomes a platform (or vector - hence the name) for delivering a protein to the cells of the body, which activates the immune response.

Earlier, on June 25, the Deputy Director of the Research Institute of Influenza. Smorodintseva on scientific work Daria Danilenko reported that the first case of infection with the Delta Plus strain was detected in Russia.

This strain is a variation of the Indian Delta variant. The WHO believes that the Indian strain is twice as contagious as the Wuhan variant. The Ministry of Health of India warned that the new strain could affect lung cells more severely.
