Surveillance Snapshot: Influenza Immunization Among U.S. Armed Forces Health Care Workers, August 2018–April 2023

Image of 3Snapshot. Influenza Immunization Among U.S. Armed Forces Health Care Workers, August 2018-April 2023.

The U.S. Advisory Committee on Immunization Practices recommends vaccination for all health care personnel against influenza to protect both themselves and their patients.1 The Joint Commission’s standard for infection control emphasizes that individuals infected with influenza virus are contagious to others before any signs or symptoms appear. The Joint Commission mandates 90% influenza vaccination for health care personnel, and health care organizations provide influenza vaccination programs for their practitioners and staff. Within the Department of Defense, seasonal influenza immunization is mandatory for all uniformed and health care personnel who provide direct patient care, and is recommended for all others (excluding those medically exempt).2-5

This graph comprises three lines oriented on the horizontal, or x-, axis, each connecting five discrete data points oriented along the vertical, or y-, axis. These three lines represent the health care worker populations within the U.S. Army, Navy, and Air Force active components. The y axis of the graph charts the annual percent of those Armed Forces health care workers who received an influenza vaccination. The horizontal, or x-, axis demarcates the preceding five influenza seasons, which begin in August and conclude in April, from August 2018 through April 2023. Influenza vaccination rates among health care workers have remained above 91.0%, but declined steadily over the five years among Air Force personnel, from 97.0% to 93.7%; dropped within the last year from 95.5% to 92.8% among Navy personnel; Army rates were fairly consistent, and lower, than the other two services until declining to the absolute lowest rate, 92.0%, in 2021-2022 but the Army rebounded to its normal range of 93.8% in the 2022-2023 season.

This Surveillance Snapshot covers a 5-year surveillance period (August 2018–April 2023) and presents the documented percentage of compliance for the influenza immunization requirement among active component health care personnel of the Army, Navy, and Air Force. In general, these health care personnel include health care specialists (DOD occupation code=13) and health care officers (DOD ocupation code=26), but exclude veterinary medicine, environmental health, biomedical equipment maintenance and repair, and health services administration and logistics personnel. In the 2022-2023 influenza season, compliance rates ranged from 92.8% among Navy health care personnel to 93.8% among Army health care personnel (Figure).
