This is my experience too. My parents are devout Catholics. Active in the church and community, charity, the whole nine yards. They are very morally upright people as well. When it comes to prayer and living their faith, they are much more spiritual than I am.

So it came as a huge shock to me when my father starting talking about people who didn't get the shot were being selfish. Thankfully, he walked that back a bit when he realized my family and I weren't going to budge, and it hasn't impacted our relationship. But they have still been dutifully getting their boosters, despite my misgivings. At this point, I pray for their health, but if they do not want to listen to my advice, I have come to terms with the fact that they are adults and can make their own decisions.
