- With each change in the virus, the vaccine immunity decreases, because the virus on the material of which the vaccine is made changes. The more viruses, the more likely new mutations are, - the doctor explained in an interview with Sputnik radio.

According to the expert, it is possible to prevent the emergence of new variants of covid by vaccinating 80-90% of the world's population, otherwise scientists will have to develop more and more new vaccines.

- If the effectiveness of the vaccine is more than 50%, the immune layer grows (the number of people protected from infection - ed.), If less, then it will stagnate or decrease due to the emergence of new variants of the virus. Then at some point it will be necessary to make a new vaccine, - Zhemchugov pointed out.

In addition, it is possible to develop a fundamentally new mechanism for the design of drugs for the prevention of infections. The expert noted that currently on the basis of the Center. The Gamaleas intend to register a technology that allows them to quickly create new drugs against the emerging varieties of COVID-19.

- With the update of the virus, it will be possible for me to vaccinate the material, to use the material from the newest virus, - explained Zhemchugov.
