It's the vaccinated people pressuring me more and more that's getting to be the problem, and people who I don't talk to much who bring it up because it's easy small talk. I've been fine saying "not yet" so far.

That's exactly what I've done too. I tell them I'll take it when I need it, which is not a lie. If I can't travel without adding it on top of the vaccine stack, I'll get it. I just won't rush into taking an experimental treatment for the fun of it.
