This quarterly measure identifies the average percentage of healthcare personnel (HCP) who are considered up to date with recommended COVID-19 vaccines among the total number of HCP who regularly work in the facility.  

The measure is reported for a quarter (3-month period). The quarterly COVID-19 vaccination coverage is determined by selecting one week per month and calculating the percentage of HCP who are considered up to date with recommended COVID-19 vaccines, then averaging 3 weekly percentages (one week from each of the 3 months in the quarter).
