In the Chumakov center, “McDonald's slogan” was used to describe the creation of KoviVak

Center them. Chumakova decided to create a vaccine against covid-19 based on the classical platform, using an inactivated virus, as he specializes in such drugs, Konstantin Chernov, deputy DIRECTOR of the center, development director, told Rossiya radio.

“Here you can jokingly refer to the slogan that McDonald's once used: “We only make hamburgers, but we make them well.” We know how to make such vaccines. We have just created a recently inactivated polio vaccine. Accordingly, we understand how these vaccines are made. We produce similar vaccines, for example, against rabies, against tick-borne encephalitis. The platform has been known for a long time, since the 50s of the last century,” he said.

Chernov explained that during the production of the vaccine, a live virus is produced, which is then killed. Only the outer shell of the virus remains, which the body recognizes as a live virus and begins to develop appropriate defense mechanisms.

According to the development director of the Center. Chumakov, when reacting to CoviVac, antibodies are produced in a relatively small amount, but their level jumps sharply when they encounter a live virus.
