Biologist explained the speed of creation of vaccines against COVID-19

Biologist Baranova: Scientists have been working on vector vaccines for 30 years the rapid invention of vaccines against coronavirus by previous developments in the creation of similar drugs against other infectious diseases. She announced this in an interview with URA.RU.

According to Baranova, the creation of a vaccine for a new pathogen is not happening from scratch. “You already have a developed chassis that was used for another, that is, in some experiments they were already on animals, and you just deploy it on an industrial scale, of course, after you rearranged the antigen from the pathogen from which you want to protect yourself, “- said the biologist.

The professor clarified that vector vaccines against COVID-19, like Sputnik V and Jonson & Jonson, are based on human adenovirus serotype 26, which scientists have been working on for 30 years. “A bunch of vaccines were made there, they just didn’t go into series, because such frenzied protection is not particularly needed for [fever] Ebola,” Baranova added.

In addition, new matrix RNA vaccines, such like Pfizer and Moderna, were also familiar to the scientific community. “The new principle of vaccines has been described in the literature, model studies have been made,” said the doctor of biological sciences.

Earlier in December, the director of the Gamaleya Center, Alexander Gintsburg, dispelled a number of myths associated with the coronavirus. In particular, the scientist pointed out that vaccination does not affect the reproductive function of the body, and this was proved at the Kulakov Institute of Obstetrics and Gynecology.
