Will the new Swine Flu Vaccine contain adjuvants such as Squalene?
Squalene is an adjuvant. Adjuvants are put into vaccines to increase the immune system.
Both live, attenuated, and inactivated influenza A (H1N1) 2009 monovalent vaccine formulations will be available initially; as with seasonal influenza vaccines, neither of these vaccines will contain adjuvants. The Food and Drug Administration (FDA) and the World Health Organization (WHO) have selected A/California/07/2009 (H1N1) for use as the strain for the vaccines currently being manufactured. To access this information, please refer to:
Use of Influenza A (H1N1) 2009 Monovalent Vaccine - Recommendations of the Advisory Committee on Immunization Practices (ACIP), 2009 http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5810a1.htm
According to current federal plans, only unadjuvanted vaccines will be used in the United States during the 2009 flu season. This includes all of the 2009 H1N1 and seasonal influenza vaccines that will be available for children and adults in both the injectable and nasal spray formulations. None of these influenza vaccines will contain adjuvants. Additional information is available at:
