Your post doesn't offer any information on why RFK Jr believes this should be revoked. The only thing I've seen on that is because there weren't double blind studies initially done to prove the safety of the vaccine. The article points out that vaccines usually don't have this type of study because a placebo could possibly the participants in the study to actually contracting the disease in question.

Why did you leave that out Joe?

I don't think RFK Jr is in any way the right fit for this important position.

I wonder if Elon Musk is secretly working on a new more compact version of the Iron Lung.
