Healthcare Personnel Influenza Vaccination in California Hospitals, 2020-21
Hospital-based health care personnel (HCP) who receive annual influenza vaccination make an important contribution to prevent transmission of influenza to patients, their families, and the community. California acute care hospitals must offer influenza vaccination at no cost to HCP, require HCP to receive the annual influenza vaccination or declare in writing that he/she declines vaccination, and report vaccination data to the California Department of Public Health (CDPH) (Health and Safety Code section 1288.7).
This report presents data from 396 California hospitals for the 2020-21 influenza season (October 1, 2020, through March 31, 2021) and also summarizes vaccination coverage by county.

Overall, California hospitals reached 79% influenza vaccination among HCP in 2020-21, representing a 7% decrease compared with the 2018-19 influenza season. In total, among 386 reported hospitals, 88 (23%) hospitals met the 90% Healthy People 2020 goal.
During the ongoing COVID-19 pandemic with the potential for concurrent COVID-19 and influenza outbreaks, it is essential for healthcare facilities to optimize all available effective influenza prevention and outbreak control interventions, including influenza vaccination of HCP. In response to this report, CDPH will provide reminders of the importance of HCP influenza vaccination on weekly healthcare facility calls and webinars.
