After recovering from COVID-19, it is generally recommended to wait about 3 months before getting a COVID-19 vaccine dose. This delay is to allow the body to recover and to reduce the risk of potential side effects, although vaccination soon after infection is not known to be harmful. The waiting period also accounts for the fact that natural immunity provides some protection for a period after infection. However, there is no strict minimum interval required, and some guidelines say vaccination can proceed as per the recommended schedule, especially if there is a higher risk of severe disease or exposure. For individuals with multisystem inflammatory syndrome (MIS), a longer wait of about 90 days is recommended before vaccination. In summary:
- Most health authorities recommend a 3-month delay after COVID-19 symptoms start or after a positive test before vaccination.
- There is no harm in vaccinating sooner, but longer intervals may enhance immune response.
- Special considerations apply for those with MIS or immunocompromised conditions.
This guidance aligns with recommendations from the CDC, Canadian Immunization Guide, and Australian immunization authorities, among others.
