Delta variant has made herd immunity impossible
I mentioned this in a post yesterday...
So keep your mask handy and get ready for another nasty winter.

The developer of the AstraZeneca shot says the Delta variant has made herd immunity impossible because vaccinated people can still transmit the virus
The Delta variant has changed the equation for achieving herd immunity, the developer of the Oxford/AstraZeneca vaccine has said.
Speaking at a UK parliamentary meeting on Tuesday, Sir Andrew Pollard, a professor of pediatric infection and immunity at the University of Oxford, said that achieving herd immunity is "not a possibility" now that the Delta variant is circulating.
"We know very clearly with coronavirus that this current variant, the Delta variant, will still infect people who have been vaccinated, and that does mean that anyone who's still unvaccinated, at some point, will meet the virus," Pollard said.
He said it was unlikely that herd immunity will ever be reached, saying the next variant of the novel coronavirus will be "perhaps even better at transmitting in vaccinated populations."

Walensky said CDC investigations have found that the amount of virus present in vaccinated people infected with Delta is similar to the levels found in unvaccinated people with Delta infections. That's an indication that vaccinated people can easily transmit the virus — even though they're less likely to get sick on the whole.
