What offers greater protection against Covid-19 – natural immunity or vaccination? It's a question that has continually been raised during the pandemic, and it has been especially relevant to those who have previously contracted the virus.
Now, a team of researchers led by faculties at the Yale School of Public Health and the University of North Carolina at Charlotte, are ready to share their insights. According to the results of their study, strong protection following natural infection is short-lived.
"Reinfection can reasonably happen in three months or less," lead author of the study Jeffrey Townsend, the Elihu Professor of Biostatistics at the Yale School of Public Health, said in a news release.
