I was thinking about this in slightly more general terms: what would it take, as a general media effort, to get the vaccine deniers on board? I think it’s possible with the right stimulus; after all, they’ll easily forget they were ever anti-vaccine in the first place. It’s just a matter of what it is. Would Fox News be enough? Would Newsmax and OAN also have to go along? Are individuals (bloggers and Facebook posters) key? I’m just not sure.
How about just a list, with stock clips, of prominent people who have gotten the vaccine, such as Donald Trump, various Fox News presenters, etc.? For public figures for whom their vaccination status is already public knowledge, I don’t think you’d need to get their consent for that.
