Vaccination of people with suspected COVID-19 symptoms or with COVID-19 recently confirmed by the laboratory should be postponed until fully recovered and once the isolation period is over.
Similarly, vaccination of people quarantined (for being contacts of a confirmed case) should be postponed until quarantine ends, but no virological or serological diagnostic test is required before vaccination. The reason is to avoid mistakenly attributing symptoms produced by the disease to the administration of the vaccine.
However, current evidence indicates that reinfection is exceptional subsequent to a natural infection. Accordingly, vaccination of people with PCR-confirmed SARS-CoV-2 infection may be delayed for 6 months. In the situation of limited vaccine supply, this will help to prioritize vaccination of people who have not yet had the disease.
In any case, vaccination of confirmed cases in isolation and from close contacts in quarantine should be postponed until the end of such measures.
