I don’t deny that there are potential side effects. However, when one person knows multiple people who have suffered some ill effect it’s obviously not about the science. By that same token I could apply my logic that I know zero people who have had any serious side effects.

I actually just suggest that they drive without seatbelts seeing as the odds of getting in a serious accident are so low in their daily life if they want to refuse the vaccine based on potential side effects. Hemming and hawing usually follows.
