- Individuals are considered up to date with their COVID-19 vaccines during the surveillance period of September 26, 2022 – December 25, 2022 (Quarter 4) for the purpose of NHSN surveillance if they meet ONE the following criteria:
- Received their last booster dose less than 2 months ago, or
- Completed their primary series less than 2 months ago
- This definition is the same regardless of immunocompromised status
