Covid, Oxford: “With Delta variant impossible herd immunity”

” It is not possible ” to achieve herd immunity with the current Delta variant of the coronavirus. This was stated by the director of the Oxford Vaccine Group, Sir Andrew Pollard, underlining that ” this virus is not measles. If 95 percent of people have been vaccinated against measles, the virus cannot spread to the population, “he said. But” the Delta variant will still infect people who have been vaccinated. And that means anyone who is not yet vaccinated. at some point it will encounter the virus and we have nothing that can completely stop that transmission, ” he added.

The concept of herd immunity is based on the fact that the vast majority of a population that gains immunity provides, in turn, indirect protection from an infectious disease for the unvaccinated and those who have never been infected before. .
