Unvaccinated people who have been infected with SARS-CoV-2 are at risk of
reinfection within a couple years

according to a model based on knowledge of SARS-CoV-2 and other
coronaviruses. Researchers combined long-term data for ‘endemic’, or
continually circulating, coronaviruses that can cause the common cold with
genetic data from SARS-CoV-2 and the closely related coronaviruses SARS-CoV
and MERS-CoV. The results suggest that the average reinfection risk rises
from about 5% at 4 months after initial infection to 50% by 17 months.
“Immunity is relatively short-lived,” says bioinformatician Jeffrey
Townsend. “You should still get vaccinated even if you got infected.”
