Increases In COVID-19 Vaccination Among NYC Municipal Employees After Implementation Of Vaccination Requirements.

In July 2021 New York City (NYC) instituted a requirement for all municipal employees to be vaccinated against COVID-19 or undergo weekly testing. The city eliminated the testing option November 1 of that year. We used general linear regression to compare changes in weekly primary vaccination series completion among NYC municipal employees ages 18-64 living in the city and a comparison group of all other NYC residents in this age group during May-December 2021. The rate of change in vaccination prevalence among NYC municipal employees was greater than that of the comparison group only after the testing option was eliminated (employee slope = 12.0; comparison slope = 5.3). Among racial and ethnic groups, the rate of change in vaccination prevalence among municipal employees was higher than the comparison group for Black and White people. The requirements were associated with narrowing the gap in vaccination prevalence between municipal employees and the comparison group overall and between Black municipal employees and employees from other racial and ethnic groups. Workplace requirements are a promising strategy for increasing vaccination among adults and reducing racial and ethnic disparities in vaccination uptake.
