Right... So how much did the "science" change on the vaccine? It was supposed to stop you from getting it. It didn't. It was supposed to stop you from spreading it. It didn't. And you can talk all you want about historical vaccines, but with Covid specifically (not MRNA generally), there were no longitudinal studies proving both efficacy and long-term safety.
I'm very happy with the decision we made. My family remains very healthy. In fact, we were just talking the other day about some of our friends' kids who seem to "catch everything" and are constantly sick. Many of these families load up on covid and flu vaccines. We take/took neither and amazingly, none of us have had the flu (I don't think I've ever had it and my kids have never had it) and a couple brushes with covid have been super minor.
Many historical vaccines have been gamechangers from a pop health standpoint. Small pox, polio... great! But we attempted to rush a vaccine for a rapidly mutating virus and force it on people who everyone knew were exceptionally low risk for any sort of complication. In fact, "the science" clearly showed that people under 50 (and especially kids) with no comorbidities were extremely low risk. So we did in fact "trust the science."
