For unvaccinated, reinfection by SARS-CoV-2 is likely

Throughout the COVID-19 pandemic, there has been much uncertainty about how long immunity lasts after someone who is unvaccinated is infected with SARS-CoV-2.
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 a lead author of the study. “Therefore, those who have been naturally infected should get vaccinated. Previous infection alone can offer very little long-term protection against subsequent infections.”
