All facilities reporting data through the National Healthcare Safety Network (NHSN) COVID-19 Vaccination Module must use the updated CDC definition for up-to-date COVID vaccination issued in June.

The details: Up to date COVID-19 vaccination includes:

• An individual who has received all doses in the primary series and all recommended booster doses, when eligible.
• Most individuals who are 50 years and older and have received a second booster dose.

Zoom in: Reporting of up-to-date vaccination status is summarized in the table below.

*Individuals with a moderately to severely immunocompromising condition are considered up to date in the following cases:

1. received an additional dose less than three months ago, if primary series was the Moderna or Pfizer-BioNTech COVID-19 vaccine; or 
2. received an additional dose less than two months ago, if primary series was the Janssen COVID-19 vaccine; or
3. received an additional dose and one booster dose less than four months ago; or
4. received a second booster dose.

If data does not reflect the updated definition, facilities are encouraged to go back into NHSN and update their data.
