Immunity acquired from a Covid infection provides strong, lasting protection against the most severe outcomes of the illness, according to research published Thursday in The Lancet — protection, experts say, that’s on par with what’s provided through two doses of an mRNA vaccine.

Infection-acquired immunity cut the risk of hospitalization and death from a Covid reinfection by 88% for at least 10 months, the study found.

The study was the largest meta-analysis to date to look at immunity following infection. It included 65 studies from 19 countries and compared the risk of developing Covid again in people who had recovered from infections to people who hadn’t been infected through September. People who had hybrid immunity, or immunity from both infection and vaccination, were excluded.

While protection from severe disease remained high, people could be reinfected, particularly with an omicron subvariant, consistent with evidence that protection against having symptoms wanes faster than protection against hospitalization and death. That was rejected earlier and caused a lot of problems and wastefulness. 

Just a thought.
