A new study by the Yale School of Public Health has analyzed data on natural immunity to estimate how often unvaccinated individuals can expect to become reinfected with COVID-19.
“The overall goal of the study was to provide an answer to a question that at this point in the pandemic would be impossible to answer empirically, which is how long after you’ve been infected by SARS-CoV-2 can you expect to possess immunity against the virus before you become vulnerable to reinfection?” Hayley Hassler, a co-author of the study, told Yale Daily News.
