The director of the Oxford Vaccine Center, Andrew Pollard, warned on Tuesday that achieving group immunity to the coronavirus “not a possibility” once the Delta variant becomes dominant.

Pollard, that led the AstraZeneca vaccine design against covid-19 together with the immunologist Sarah Gilbert, argued before a parliamentary committee that vaccination programs should not be based on the idea of ​​achieving that “herd immunity.”

“We clearly know that with the current variant of the coronavirus, the Delta, (the virus) will continue to infect people who have been vaccinated, and that means that anyone who has not yet been vaccinated, at some point will come across the virus, “the scientist told the deputies.

He further stated that in the future there could be “a variant that is perhaps even better transmitted between vaccinated populations”, so “that provides even more reasons not to revolve vaccination programs around group immunity.”

“Consolidation phase”

Six months from now, Pollard thinks that a “consolidation phase” in the fight against the virus will take place in the United Kingdom and that the covid will go from an “epidemic” to a “endemic” evil.

The public health agency of England (NHS England), published last week a report in which it warns that there are indications that “the levels of the virus in those vaccinated people who are infected with the delta may be similar to those found in unvaccinated people “, which affects the ease of transmission of the pathogen.

Among nearly 1,500 patients hospitalized with the delta variant in the UK since 19 July, 55.1% were not vaccinated, while 34.9% had received the complete guideline, said that report.
