Vaccines have been shown to be effective in protecting against severe forms of Covid-19. But do they provide additional protection when the individual has already been infected before? According to Brazilian researchers who have evaluated four vaccines in this context, it is yes.

They conducted their assessment on CoronaVac vaccines [Sinovac]ChAdOx1 nCoV-19 [AstraZeneca]Ad26.COV2.S [Janssen]and BNT162b2 [Pfizer-BioNtech].

To do this, they compared the evolution of an infection in more than 30,000 cases of reinfection after a first infection followed by a vaccine with a control group, including people who had never been infected before immunization.

For all four vaccines, they were able to find that having been previously infected with SARS-CoV-2 and then vaccinated conferred “additional protection against symptomatic infections and severe cases in individuals already previously infected”, note the authors.
