Reaching herd immunity is “not a possibility” with the current Delta version, the head of the Oxford Vaccine Group has said.Giving evidence to MPs on Tuesday, Prof Sir Andrew Pollard said the fact that vaccines did not stop the spread of Covid suggested reaching the threshold for total resistance in the population was “legendary”.”Although the existing vaccines are really reliable at avoiding severe Covid health problem and death, they do not stop a totally vaccinated person from being contaminated by the infection that triggers Covid-19. The idea of herd or population resistance relies on a large majority of a population getting immunity– either through vaccination or previous infection– which, in turn, offers indirect defense from a contagious disease for the unvaccinated and those who have actually never been previously infected.Data from a current React study conducted by Imperial College London suggests that completely vaccinated people aged 18 to 64 have about a 49% lower danger of being infected compared with unvaccinated individuals.”The concern of whether or not to immunize under-16s, as nations consisting of the United States, Ireland and Israel have done, has also provoked scientific dispute in the UK.The JCVI has recommended just vulnerable children aged 12 to 15 be immunized, and those who live with at-risk grownups. Some critics have actually said that rich countries with high adult vaccine coverage, such as the UK, must not be hoarding dosages for kids however need to donate those dosages to bad countries, numerous of which have actually barely immunized any of their most at-risk populations.But Prof Devi Sridhar, the chair of international public health at the University of Edinburgh, pointed out that the only vaccine authorised for use in children aged 12 to 15 in the UK was the Pfizer/BioNTech vaccine.
