We have listed vaccine ingredients (substances that appear in the final vaccine product), process ingredients (substances used to create the vaccine that may or may not appear in the final vaccine product), and growth mediums (the substances vaccines are grown in) for 31 vaccines commonly recommended by the Food & Drug Administration (FDA) and the Centers for Disease Control (CDC.) Controversial products used to make vaccines: African Green Monkey (Vero) cells, aluminum, cow products, formaldehyde, human fetal lung tissue cells, insect products, and mouse brains.

Though not listed, each vaccine contains strains of the virus being vaccinated against. Each vaccine entry links to the manufacturer’s package insert that contains information about dosage, ingredient quantity, and how the vaccine is made.

Some vaccines, like influenza vaccines, are modified frequently and you may wish to consult the package inserts online and your doctor for the most current information.
