I may be in the minority here but I’m don’t think it’s a valid comparison to look at 1 vs 2 vaccine doses IF you aren’t discussing only people who received two doses. The reason is that the populations are structurally different. People who had only 1 dose may be restricted from getting the 2nd dose (for example, due to having to wait the mandatory time between doses, another health complication, changes to local regulations regarding dosing or payment coverage. The point is that those who are at risk of an adverse event after 2 doses are necessarily different from those who have only had 1 dose.
