Vaccine Ingredients

Antivaccine activists claim that vaccines contain all sorts of terrifying poisons. Is this true?

Antivax conspiracy theorists tell us that vaccines are deadly and contain some extraordinary toxins. Let’s examine a few of these ingredients, starting with:

FORMALDEHYDE: Absolutely true. Formaldehyde is used to sterilize some vaccines. We use formaldehyde for this because it’s found naturally in the human body, as it’s a normal byproduct of metabolism and digestion.

ANTIFREEZE: False. However some vaccines are sterilized with something called 2-phenoxyethanol, which is also used as a topical antibacterial for wounds. This and antifreeze come from the same family of hydrocarbons, but they are not the same thing.

MERCURY: Sort of true. Some vaccines are sterilized with thimerosal, also used in contact lens fluid and many other products. However, it contains mercury bound as an ethyl — the version of mercury that can be dangerous has to be bound as a methyl, which is different.
