OREANDA-NEWS. The «delta» strain of coronavirus makes it impossible for the population to form collective immunity. This statement was made on Tuesday, August 10, in London, by the director of the Oxford group for the development of the AstraZeneca vaccine, Professor Andrew Pollard, to the British parliamentary group on coronavirus.

«The problem is that this virus is not a measles virus. If 95 percent of the population is vaccinated against measles, the measles virus can no longer be transmitted. The «delta» strain will also infect those who have been vaccinated», The Guardian quotes the scientist.

As Pollard pointed out, people who have not been vaccinated will sooner or later encounter the virus, there is no means to completely stop its transmission. At the same time, he noted that there are no reasons for panic at the moment, since the existing vaccines, although they do not save from infection, are very effective in protecting against the severe course of COVID-19.

Even if the level of antibodies decreases after vaccination, the human immune system is likely to remember about the vaccination for decades and will provide a certain degree of protection when encountering the virus, Andrew Pollard stressed.

As The Guardian reminds, a recent research by Imperial College London suggests that fully vaccinated people aged 18-64 years are 49 percent less likely to become infected with coronavirus than unvaccinated people.
