Flu vaccination info for UC Davis patients
Because the viruses for seasonal flu and H1N1 or "swine" flu are different, they require different vaccinations.
UC Davis clinics have received a limited supply of the H1N1 vaccine and are providing it to certain patients in conformance with CDC guidelines as supplies last. Due to extraordinary levels of demand and limited availability, our supply of the seasonal vaccine is sometimes limited as well.

Seasonal flu vaccinations

The seasonal or "common" flu and H1N1 or "swine" flu viruses are different, and require different vaccinations for patients.
Seasonal flu occurs every year, typically in late fall, winter and early spring. The vaccine for this disease changes every year based on what is known about the types and strains of seasonal flu viruses that will be prevalent in a given year. About two weeks after vaccination, antibodies that protect against influenza virus infection develop in the body.
Due to extraordinary levels of demand and limited availability, our supply of seasonal vaccine is sometimes limited. As it receives additional supplies, the health system will make the seasonal vaccine generally available to patients. Please call your primary care provider to find out when you should make an appointment for the vaccine.
Note: The seasonal flu vaccine does not provide protection from H1N1 influenza, which is a new strain of infection.
H1N1 flu vaccinations
Because it is a different virus, the new H1N1 or “swine flu” requires a separate vaccination.
UC Davis clinics have received a limited supply of the H1N1 vaccine and are providing it to certain patients in conformance with CDC guidelines.
The groups recommended by the CDC to receive the 2009 H1N1 influenza vaccine include:
— pregnant women
— persons who live with or provide care for infants aged 6 months or younger (e.g., parents, siblings, and daycare providers)
— persons aged 6 months to 24 years
— persons aged 25 to 64 years who have medical conditions that put them at higher risk for influenza-related complications, including:
- asthma
- neurological and neurodevelopmental conditions
- chronic lung disease
- heart disease (such as congenital heart disease, congestive heart failure and coronary artery disease)
- blood disorders (such as sickle cell disease)
- endocrine disorders (such as diabetes mellitus)
- kidney disorders
- liver disorders
- metabolic disorders
When it receives additional supplies, UC Davis Health System will make the H1N1 vaccine generally available to patients. Please call your primary care provider to find out when you should make an appointment for the vaccine.
Sacramento County’s public health department has also received H1N1 vaccine and has released a schedule of vaccination clinics through January. Because supplies are limited, the vaccinations at some events may be limited to CDC priority groups.
