I am against both, with some exceptions.
If we are talking about COVID vaccine, I agree. It's a bad illness, but not in the category of "bad enough" that everyone should be forced to get vaccinated in order to save the human species. Survival rate for COVID is pretty high. And those compromised individuals who are likely to get really sick from COVID probably would also get really sick from Flu, RSV, etc..
As for abortion - for the most part I think choice is between woman and doctor for the whole pregnancy. But after ~24 weeks I think medical emergency or health of the fetus should be the only reason for abortion. A healthy fetus could be delivered naturally at that point. (Although I doubt there are many (any) abortions that happen after 24 weeks where the fetus is viable).
