evidence: "There is no vaccine that includes everything on this list," Dr. Kawsar R. Talaat, associate professor of international health at the Johns Hopkins Bloomberg School of Public Health, told us in a phone interview. "I think that they have gathered these ingredients and use different names for them in order to scare people as much as possible." [...] Anyone can check the Johns Hopkins database or consult the package inserts to see that none of the current flu vaccines contains ethanol, aluminum dye or aluminum, any type of acetone, "monkey kidney cells" or Vero cells, "fetal cow serum" or bovine serum, barium, E. coli, "cow muscle tissue," "DNA from pig circoviruses (PCV)", "embryonic guinea pig cells," human albumin (a protein naturally made in the liver), "Mueller’s media (containing cow extracts)," or dextrose (a type of sugar), as the meme incorrectly claims. [...] Vaccines may also contain some leftover products from the manufacturing process. As explained by CHOP’s Vaccine Education Center, since the ingredients of the vaccine come from biological systems, it’s sometimes impossible to completely remove substances used during the process. Although most of the time the amounts that remain in the vials are insignificant, the substances still need to be listed.
