COVID vaccines never affected other people because they don't reduce transmission, and even if they did, the point of a vaccine is individual protection. If you think it works then it didn't matter what other people choose. And this holds true for many vaccines.

Yet, again, odd silence from the pro-choice crowd. Clearly they don't believe in choice nor bodily autonomy.

Abortion on the other hand does always affect other people, if you believe the fetus is a person.

But most importantly, yes you do have to be consistent. If you can't be consistent because you feel it requires adopting extreme positions then you need to rethink your moral code, because clearly, you may find that your position isn't as morally clear as you thought.
