In this episode of “Vaccine Support,” the folks from WIRED sat down with pediatrician Dr. Paul Offit to answer the internet’s biggest questions about vaccines, and he delivers it all with the calm energy of a man who has explained this a lot… and still somehow kept his sense of humor.

He covers how vaccines are developed, why babies get so many, what “vaccine memory” actually means, and why “natural immunity” is really just “I survived this, thankfully.” He even tackles the MMR-autism myth, herd immunity, and yes… whatever is going on with RFK Jr.

It’s smart, clear, and occasionally funny in that “doctor quietly roasting bad science with a smile” kind of way. If you want a solid, no-nonsense breakdown of how vaccines really work, this one’s absolutely worth a watch.
