UC Davis Health is now offering updated 2026-27 flu and COVID-19 vaccines for patients. These vaccines are designed to help protect against the viruses expected this respiratory virus season.
Influenza, or the flu, is a respiratory illness that affects the nose, throat, and lungs. Symptoms can range from mild to severe. In some cases, the flu can lead to hospitalization or even death.
COVID-19 is an infectious disease that often causes symptoms similar to a cold or the flu. Most people recover, but some can become very sick and develop serious health problems.
Vaccination is the best protection against serious illness from flu and COVID-19. Health experts recommend flu vaccines for everyone ages 6 months and older. COVID-19 vaccines are especially recommended for young children ages 6 to 23 months, those 65 years of age or older, and other priority groups with risk factors for severe disease and are available to anyone ages 6 months and older who chooses protection.
For the 2026-27 respiratory virus season, UC Davis Health is offering the following flu and COVID-19 vaccines:
Flu vaccines
FluLaval: An injectable inactivated influenza vaccine used to prevent illness caused by influenza A and B viruses.
- Who can get it: Approved by the U.S. Food and Drug Administration (FDA) for people 6 months and older.
- How it works: The vaccine helps your body build protection against the flu by teaching your immune system to recognize and fight the flu viruses included in that season's vaccine.
- How it is given: It is administered as a single shot in the upper arm.
- Egg content: It is made using egg-based methods, however the Centers for Disease Control and Prevention (CDC) says people with egg allergies can receive any flu vaccine that is right for their age and health status. If you have had a severe allergic reaction to eggs and have concerns, talk with your doctor about getting vaccinated.
Fluzone High-Dose: An annual influenza vaccine specifically made for adults 65 and older to provide a stronger immune response than standard-dose flu.
- What makes it different: This vaccine contains a higher dose to help create a stronger immune response. It has four times more flu-fighting antigen than a standard flu shot.
- Who should get it: It is recommended for adults 65 and older because the immune system becomes weaker with age.
- How it is given: It is administered as a single shot in the upper arm.
- How well it works: Studies show it provides better protection against the flu and can help reduce flu-related hospital stays in older adults compared to a standard-dose flu shot.
- Egg content: It is made using egg-based methods. The CDC says people with egg allergies can receive any flu vaccine that is right for their age and health status. If you have had a severe allergic reaction to eggs and have concerns, talk with your doctor about getting vaccinated.

- What it protects against: The 2026-27 vaccine is designed to protect against the COVID-19 XFG variant, a descendant of the JN.1 strain.
- How it works: It trains the immune system to recognize and fight the COVID-19 virus, significantly lowering the risk of severe COVID-19, hospitalization and death.
- How it is given: Given as a shot in the muscle.
