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. “This is really good news, in the sense that protection against severe disease and death after infection is really quite sustained at 10 months,” said the senior study author, Dr. Christopher Murray ... at the University of Washington. 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. The immunity generated from an infection was found to be “at least as high, if not higher” than that provided by two doses of an mRNA vaccine, the authors wrote. While Murray and Wachter agreed that vaccination remains the safest route, having a past Covid infection should at least be considered in policymaking decisions going forward, such as vaccination requirements, they said. “What Europe did with this evidence made a lot of sense, which is where evidence of past infection was seen as essentially equal to vaccination in terms of requirements to go into events or for employment,” Murray said.
Note: It's worthy of mentioning that much of the media previously dismissed the effectiveness of natural immunity to protect against COVID, with mainstream media platforms blatantly claiming that natural immunity is "not panning out" and "comes at a cost."
