I don't think it's enough to say people get vaccinated and we didn't see this in the past. This is quite different. Many people are afraid of this vaccine more than others in the past. I've had countless arguments with family trying to convince them it's okay. Their arguments are A) it's mRNA, which is new... And B) they argue it was rushed.
I can't help but think about how someone with that mental state would feel while in the waiting room.
