As an "antivaxxer" (not by any reasonable use of the word, but that seems to be the state of the language right now), I would not deny any rape victim from getting an abortion. I don't think I've observed this overlap you mention, other than being referenced in comments like yours.

(I'm sure there are traditional pre-2020 antivaxxers out there, I just never come across them in real life)

On bodily autonomy, I see a lot of this "I'm not touching you, I'm not touching you!" kind of argument. Sure, technically nobody is using immediate physical force. By some strict literal interpretation, you are correct. I don't think that's what people have in mind when they say bodily autonomy though.
