Mandatory Influenza Vaccination or Masking of Health Care Workers During Every Influenza Season

As Health Officers for Alameda County and the City of Berkeley, we are updating our joint Health Officer orders (originally dated Aug. 28, 2013) mandating that all licensed health care facilities in Alameda County and the City of Berkeley require their health care workers (HCWs) to receive an annual influenza vaccination or, if they decline, to wear a mask during every influenza season while working in patient care areas. This order applies to all facilities regardless of documented HCW influenza vaccination rate. The 2017update defines Influenza Season as November 1 to April 30 of the following year. This order is ongoing and applies to each influenza season, unless rescinded or modified.
