Said a specialist in serious infectious diseases and immunity d. Vladislav Zhemchugov, we will need to develop a new vaccine against “Covid-19” if the effectiveness of existing vaccines drops to 50%.
He pointed out that the coronavirus is constantly mutating in its struggle with immunity, including immunity resulting from vaccination.
He explained, “No one can rule out that the virus’s ability to combat immunity resulting from vaccination will increase as a result of mutations and selection. If that ability exceeds 50%, vaccination will become practically useless and it will be necessary to develop a new vaccine, and vaccination must be done quickly so as not to pass through another cycle.”
The specialist added that the reason for the high number of infections with the Corona virus is due to the mutations of the virus that reduced the effectiveness of drugs by 30%. He said young people are getting sick more often.
It is noteworthy that the Ministry of Health had previously issued a license to conduct clinical tests of the “Coviac” vaccine against “Covid-19” among volunteers over the age of 60 years. About 250 people are participating in the tests. The tests are being conducted at the “Mechnikov” Institute for Vaccines and Serology in Moscow, “Akademie Wagner” State University of Medicine and the Military Medicine Unit in the Russian province of Novosibirsk.
