NEW HAVEN, Conn. - Scholars at the Yale School of Public Health say we still don’t have enough empirical data to know how long natural immunity lasts after COVID-19 infections, but the results of their recent study appear to indicate it doesn’t last very long.The study, published on Oct.
1 in The Lancet Microbe, suggests unvaccinated people are at risk of reinfection 16 months after recovering from COVID-19.The study showed an unvaccinated person runs a 5% risk of reinfection roughly three months after recovery.
