One of the frequent criticisms we initially heard about the messenger RNA vaccines was that we didn't have much experience with them and they were new. That argument is getting a little tired, in that we've been using them for over two years and, seemingly, we haven't seen any great rise in adverse effects as a result of the vaccines.
I think a lot of people, especially people with kids, and I have a bunch of kids.... When you're talking about the combination vaccine, this is a new vaccine, so what can you say to reassure us that this combination vaccine is as safe as the original vaccine?
