I am from a traditional Catholic chapel in Louisville, and my chapel is about 250-300, and I know two people who got the vax, one wife and one gal in her 20's who moved to the Big Apple. In nearly three years I have heard of maybe a couple people getting "COVID," whatever that means. Certainly no one has died from COVID, and no one has become deathly sick from COVID. If your husband is not convinced by common sense, I guess my only advice is pray and say no.
If a somewhat sizeable church has a 99% non-vaccination rate and there are little or no cases of COVID, then common sense says one thing, WE HAVE BEEN SCAMMED ON THE COVID QUESTION. I do not know how to express this any more simply. This is an inductive argument, but it is a very strong inductive argument.
