For unvaccinated, reinfection by SARS-CoV-2 is likely, study finds | YaleNews

Now a team of scientists led by faculty at Yale School of Public Health and the University of North Carolina at Charlotte have an answer: Strong protection following natural infection is short-lived.

Reinfection can reasonably happen in three months or less,” said Jeffrey Townsend, the Elihu Professor of Biostatistics at the Yale School of Public Health and the study’s lead author. “Therefore, those who have been naturally infected should get vaccinated. Previous infection alone can offer very little long-term protection against subsequent infections.”

The study, published in the journal The Lancet Microbe, is the first to determine the likelihood of reinfection following natural infection and without vaccination.
