Comparing COVID-19-related hospitalization rates among individuals with infection-induced and vaccine-induced immunity in Israel
Abstract
The relative degree of immunity to SARS-CoV-2 provided by combinations of natural infection, vaccination, and booster doses is unknown. Here, the authors show that infection-induced immunity provides more protection against COVID-19-related hospitalization than non-recent vaccine immunity, but less than booster vaccination.
