Polysorbate 80 in Vaccines

What is polysorbate 80 and why do they put it in vaccines?

Polysorbate 80, also known as tween 80, is an emulsifier. According to the FDA, it “helps ingredients mix together and keep them from separating.”

It is also used as a food additive, most notably as an emulsifier in ice cream.

Polysorbate 80 is not a sterilization agent.

It is safe and its presence in vaccines is certainly not a reason to be scared to get your kids vaccinated and protected.
