Flu Vaccine Q&A

What’s the role of eggs in flu vaccines? I’m allergic, and have been told I can’t have certain vaccines like FluMist.

The process of creating flu vaccines is far from simple but, in short, the role of eggs in the FluMist vaccine allow for virus replication. If you have an egg allergy, talk to your doctor or pharmacist about which flu vaccine is right for you and ask about Flublok. Flublok is a vaccine that is not made with eggs.
