There have been several videos I've seen clips of from last year where there is a big room of people sitting in rows of folding chairs who are waiting their turn to get the shots. And then out of the blue one person who has just gotten theirs suddenly faints or falls over and starts seizing. Nurses rush over and attempt to assist the collapsed person.

Everyone in the room stays in their seat and watches. No one leaves. No one stands up and speaks out. No one questions what is happening. Insane!
