Building collective immunity against the new coronavirus is impossible due to the spread of the Delta version, according to the Guardian, citing the authoritative British expert Andrew Pollard.
He heads a group of vaccine researchers at Oxford University.
“The problem is that this virus is not measles. If 95 percent of the population is vaccinated against measles, the virus cannot spread to humans, ”said Andrew Pollard of the parliamentary group on the new coronavirus. Delta can infect people who have been vaccinated. This means that anyone who has not been vaccinated will sooner or later be exposed to the virus. And we don’t have anything that can completely stop the transmission of the infection. “
The expert also noted that there is currently no evidence of the need for a third dose of the vaccine, as the vaccinated person’s immune system will be able to provide some protection against the virus even decades later, despite declining antibody levels.
Delta variant renders herd immunity from Covid ‘mythical’
Avec le variant Delta, atteindre l’immunité collective contre le Covid est un «mythe » selon le chef de l’Oxford Vaccine Group, le professeur Sir Andrew Pollard.

The delta variant of the new coronavirus was first discovered in India last October. The Indian Institute of Medical Research says it can infect people even after being vaccinated with Covaxin and Covisheld used in the country.
Delta Plus is considered even more contagious.
A recent study from Imperial College London shows that fully vaccinated people between the ages of 18 and 64 are about 49 percent less likely to be infected than unvaccinated people. Immunized people are three times less likely to give a positive test result after contact with an infected person than non-immunized people.
