ANALYSIS: Five reasons why COVID herd immunity is probably impossible

https://www.nature.com/articles/d41586-021-00728-2

As COVID-19 vaccination rates pick up around the world, people have reasonably begun to ask: how much longer will this pandemic last? It’s an issue surrounded with uncertainties. But the once-popular idea that enough people will eventually gain immunity to SARS-CoV-2 to block most transmission — a ‘herd-immunity threshold’ — is starting to look unlikely.

OPINION : Wrong time to ease restrictions--NY Times editorial

...

This is a precarious moment in the fight against the coronavirus in the United States. Case counts are declining. The death rate is slowing down. The country finally has a president who takes the crisis seriously. The vaccination rollout has been a bumbling mess, but the situation is improving, and it will get better still: The Federal Emergency Management Agency has been activated to help administer shots, the Food and Drug Administration could authorize a third vaccine for emergency use by the end of this month, and President Biden is partnering with clinics in underserved communities to correct for early vaccination inequities.

n the meantime, officials at the Centers for Disease Control and Prevention are pleading with the American public to strengthen its resolve on measures to reduce viral spread, like physical distancing, mask wearing and avoidance of settings where the virus is likely to spread most easily — think a restaurant’s dining room or a large, indoor wedding. The C.D.C. is also asking state leaders not to let up on closings and restrictions just yet.

Do Curfews Slow the Coronavirus?

With coronavirus infections rising and a contagious new variant threatening to accelerate the pandemic, France has implemented a stringent 6 p.m.-to-6 a.m. curfew. Citizens nationwide are sequestered indoors, and businesses must close down.

In Quebec, Canadian officials imposed a similar restriction earlier this month, running from 8 p.m. to 5 a.m. It has frayed nerves: Notably, a woman who was walking her boyfriend on a leash at 9 p.m. has argued that this was permitted during the curfew, surely one of the pandemic’s most unexpected moments.
