Egg Food Allergy
The H1N1 swine flu vaccine is incubated in chicken eggs, which are a common food allergy in infants and young children. Eggs are among the top food allergens, along with milk, wheat, soy, nuts and peanuts, and fish and shellfish [The Food Allergy & Anaphylaxis Network].
Thimerosal (Mercury)
Most batches of H1N1 vaccine, as well as other flu vaccines, contain thimerosal, a mercury-based preservative which has been associated with brain and immune system dysfunction, including autism [SafeMinds: Mercury and Autism].
Limited Testing Experimental Vaccine
According to the U.S. Food and Drug Administration, the H1N1 vaccine will be released to the public after 1 to 3 weeks of testing on a few hundred children and adults [FDA. Regulatory Considerations Regarding the Use of Novel Influenza A (H1N1) Virus Vaccines. Office of Vaccines Research and Review, 2009].
