Vaccination may be offered regardless of a person’s history of symptomatic or asymptomatic SARS-CoV-2 infection.
Vaccination is still important following natural infection, as it can boost the person’s immunity and provide added protection against reinfection.
Persons with PCR-confirmed SARS-CoV-2 infection should be vaccinated after they are no longer in isolation and do not have a fever.
WHO does not recommend pre-vaccination screening for prior infection.
