Achieving herd immunity to the coronavirus is not possible with the Delta variant, because the virus is spreading all the time and also infected people who are fully vaccinated, British scientists said on Tuesday.
- According to researchers in the UK, it will be difficult to achieve herd resistance with the Delta variant
- This is because the virus also infects fully vaccinated people, so further transmission cannot be inhibited.

– The problem with this virus is that it is not measles. If 95 percent. people have been vaccinated against measles, the virus cannot spread through the population. However, in the case of the coronavirus, we can see very clearly that the Delta variant will continue to infect people who have been vaccinated, which means that anyone who has not been vaccinated will come into contact with the virus at some point – said prof. Andrew Pollard, head of the team of scientists at the University of Oxford who developed the vaccine produced by AstraZeneca. Pollard answered questions from MPs from the cross-party coronavirus group on Tuesday.
– We have nothing to (completely) stop the transmission, so I think we are in a situation where herd immunity is not possible and I suspect the virus will create a new variant that will be even better at infecting people who are vaccinated– added.
Other scientists also spoke in a similar vein.
The concept of herd immunity is unattainable because we know the infection will spread in unvaccinated populations, and the latest data suggests that two doses are probably only 50%. protection against infection, said Paul Hunter, professor of medicine at the University of East Anglia and an expert in infectious diseases.
In turn, Devi Sridhar, professor of global public health at the University of Edinburgh, warned that it was unlikely to reach some “magic threshold” after which COVID-19 would stop spreading.
Collective Immunity – What Is It?
Herd immunity, also known as herd immunity, is when such a large proportion of a given population has become immune to infection, through vaccination or disease, to indirectly protect unvaccinated people.
Until recently, it was hoped that the increasing number of vaccinated UK residents would create a protective ring around the population. Just last week, the Joint Immunization and Immunization Committee (JVCI) gave this argument justifying the recommendation to start vaccinating 16- and 17-year-olds.
In the UK, 75% are now fully vaccinated. adult population.
