Orange County Health Officer Issues Annual Influenza Immunization Order on September 28: Respiratory Virus Season Set as November 1 to April 30, All Health Care Workers in the County Must Be Vaccinated
SANTA ANA, Orange County, California — Orange County Health Officer Regina Chinsio-Kwong issued a health officer order on September 28 requiring all health care workers who provide care in Orange County to receive an annual influenza vaccine for the current season. The order defines the respiratory virus season as November 1 through April 30 and names October as the optimal vaccination period, allowing at least two weeks to build immunity.
The order applies to licensed facilities including general hospitals, skilled nursing facilities, long term care facilities, emergency medical services agencies, dialysis centers, home health agencies, primary care clinics, ambulatory surgery centers and hospice facilities. It covers paid and unpaid employees, contractors, students and volunteers with direct patient contact or work in patient care areas, unless a medical or religious exemption applies.
The order cites national health care worker influenza coverage falling from 80.6 percent in the 2021 to 2022 season to 76.3 percent in the 2024 to 2025 season, and influenza accounting for as high as 6.3 percent of all hospitalizations and 11.8 percent of emergency room visits in particular seasons. The order remains in effect until revised, rescinded, superseded or amended in writing by the health officer.
