Ingredients in the flu shot With all of the different flu vaccines on the market, the ingredient list varies a little from shot to shot. Common troublesome ingredients include polymyxin, beta-propiolactone, formaldehyde, aluminum, thimerosal, polysorbate 80, and neomycin. All of the Ingredients are Toxic, but many are known carcinogens
These are called âtrivalentâ flu vaccines. Now, some flu vaccines protect against 4 strains. These are called âquadrivalentâ flu vaccines. After the CDC forecasts which flu strains are likely to circulate, flu vaccine manufacturers decide whether to design a flu vaccine that includes 3 strains (2 A and one B) or 4 strains (2 A and 2 B). A quadrivalent vaccine that helps protect against 2 A strains and 2 B strains may reduce the risk of being unprotected against the flu. To learn more, visit the CDC website at. http://www.cdc.gov/flu/
