“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, the director of the Institute for Health Metrics and Evaluation at the University of Washington.
The findings may be a small silver lining to the
explosive omicron outbreak of last winter. With so many people infected, many most likely still benefit from that protection against severe disease, Murray said.
Still, experts stress that vaccination is the preferable route to immunity, given the risks of Covid, particularly in
unvaccinated people.
“The problem of saying ‘I’m gonna get infected to get immunity’ is you might be one of those people that end up in the hospital or die,” Murray said. “Why would you take the risk when you can get immunity through vaccination quite safely?”
