Watch video: The Flu Vaccine
Who is most vulnerable to the flu?
Getting the annual flu vaccine is especially important for those who are:
- 65 and older
- People with medical conditions, such as asthma, diabetes and chronic lung disease
- Pregnant women
- Those who live with or provide care for these individuals
Flu vaccination formulation
The World Health Organization and the CDC select the flu viruses for each year’s vaccine based on the Southern Hemisphere’s flu season, which occurs before the Northern Hemisphere’s flu season. This year’s flu vaccines are all quadrivalent, which means they cover the four most likely strains of the flu virus expected this season (2 A strains and 2 B strains). All available vaccines are also preservative-free and thimerosal-free, and do not contain gluten or latex.
The vaccines provided at UCLA Health include
- Fluarix - A standard-dose injection. May contain small amounts of egg protein. Not for people with severe egg allergies or history of anaphylaxis.
- Fluzone High-Dose - A high-dose injection for adults who are 65 years and older. Contains four times the amount of antigen as the Fluarix vaccine. If the high-dose vaccine is not available, elderly patients may receive the standard dose Fluarix vaccine.
- FluMist - A nasal mist for children and adults between 2 and 49 years old. Not for people with decreased immunity.
- Flublok - A standard-dose injection for people with severe egg/egg-protein allergies.
