“If we are talking about protection against infection, then nothing better than specific immunoprophylaxis, that is, vaccines, does not exist in this regard.
And this is a very powerful defense for the body,” he said.
He also explained that the problem with coronavirus is that it mutates very quickly, and therefore vaccines do not provide sterile immunity from infection, but "perfectly" prevent the severe course of the disease.
“Of course, no hardening, jogging every day, etc. will not provide even a close level of protection, like effective and high-quality vaccines,” Kryuchkov said.
Earlier, the director of the Scientific Information Center for the Prevention and Treatment of Viral Infections, Georgy Vikulov, in an interview with NSN, commented on the situation with the pandemic against the backdrop of the spread of the omicron coronavirus strain.
