What do vaccines really contain? Why do people still believe they cause autism? And who keeps spreading these lies?

In honor of Immunization Awareness Month, this special episode of Infectious Dose is your guided tour through our vaccine safety series. Heather maps out the key episodes that break down myths, expose disinformation campaigns, and explain the real science behind some of the most common vaccine fears. From “Too Many Too Soon” to the truth about mRNA vaccines and RFK Jr.’s ACIP overhaul, this curated “booster dose” is perfect for new listeners, long-time followers, or anyone seeking facts they can trust. Use it to figure out which episode to listen to next or share with a friend on a quest for the truth about vaccines, who's not sure where to start.
