Are you saying Offit is the nutjob, or the author of the article? Because I don't think Offit is, see [0]. As for the author, I don't know. To be clear, Offit is talking about the third dose, not the first two, he thinks you should get those. See, if the first two doses pretty much get rid of the risk of severe disease, why would you risk myocarditis from a third dose? See [1] for his reasoning, but if you don't trust Epoch, you can watch the TWiV episode above, where there's no edits or time pressure, and he can respond to all comments by the hosts.
