Yes, there are educated people and educated reasons to be skeptical of vaccines.
But in practice, at least in America, that represents a small portion of the entire vaccine skeptical community.
Skeptical seems an accurate description too, as most of them couch their beliefs in "Well, I'm just asking the question"ism.
Through and through anti-vaccine people are a smaller group.
What does this mean? People who don't know a lot about biology? That's effectively everyone who isn't a biologist (and probably even some who are), which is effectively everyone.
> who latch onto vaccines as their cause du jour
That sounds like more than skepticism to me.

I have no way of evaluating whether this is true beyond gut feelings. Do you?
I don't think we have effective language to talk about this stuff.
You saying "vaccine skepticism" (or the real boogey man, anti-vaxxer) could mean anything from person who thinks the Jews are injecting microchips into us all, all the way to a person who has gotten all sorts of vaccines except for specifically the mRNA ones.
Obviously, these two people are very different cases.
In a discussion about cars, someone could say they wouldn't buy a Ford, and nobody feels the compulsion to call them anti-car. (And they probably actually understand some details about the car beyond eli5 marketing materials. Perhaps that explains it).
