Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are in the vaccine.
Annually the influenza viruses (seasonal flu) vaccine protects against the most targeted and common influenza infections during the foreseeable coming season. Traditional flu vaccines (called “trivalent” vaccines) are made to protect against 3 flu viruses:
- Influenza A (H1N1) virus
- Influenza A (H3N2) virus
- Influenza B virus
Additionally there are flu vaccines made to protect against 4 flu viruses (quadrivalent vaccines). These vaccines protect against the same viruses as the trivalent vaccine and an additional B virus.
CDC Recommends Use of:
- Injectable influenza vaccines
- Inactivated influenza vaccines
- Recombinant influenza vaccines
- Nasal spray flu vaccine (live attenuated influenza vaccine or LAIV) should not be used.
Note: Both trivalent (three-component) and quadrivalent (four-component) flu vaccines will be available.
