West Coast Health Alliance issues 2026-2027 respiratory virus vaccine recommendations

The California Department of Public Health (CDPH) and the West Coast Health Alliance (WCHA) have issued immunization recommendations for the 2026-2027 respiratory virus season. The guidelines focus on protection against COVID-19, influenza, and respiratory syncytial virus (RSV) to reduce serious illness, hospitalizations, and healthcare system strain.

The recommendations are informed by national medical organizations, including the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, and the American Academy of Family Physicians. Key priority groups include the youngest and oldest individuals, pregnant people, those in congregate settings, and healthcare workers.

The WCHA, a partnership between California, Hawaii, Oregon, and Washington, emphasizes making these immunizations accessible to all residents. Specific guidance includes COVID-19 vaccine availability for persons 6 months and older, and RSV protection strategies for infants and pregnant individuals.
