He is personally responsible for the rotavirus vaccine (saving thousands of lives a day) and has been enormously influential in multiple other avenues of immunobiology research. (He was a key part of investigating Andrew Wakefield’s claims)
Here, in the Q&A session after a great talk, a man attempts to impugn Offit and accuses him (and Anthony Fauci for some reason) of corruption and malfeasance.

Go to the 1:10 mark to watch. (And the whole talk is great)
