Adjuvants will not be used in the H1N1 swine flu vaccine. The issue of adjuvants was raised a few weeks ago, when some believed that vaccines in the United States would be shipped with these additives due to shortages of the vaccine. This turned out not to be the case.
Many people believe that the adjuvants may be toxic. To help allay these fears, and because we were able to produce enough vaccine for the country, flu vaccines this season will not contain adjuvants.
