You perhaps can’t. I can.

It's a fallacy of false equivalence to compare vaccination against disease to abortion..

The history of the concept of abortion as it applies to the politics in the US is quite interesting. Since it is so controversial a topic I will let you do the research on this. Start by Googling the terms and see where you get.

I have the right to do what I want with my hand. It's my hand after all. But, I don't have the right to slap you with it. I don't have the right to steal with it. When my actions affect other people, that's when there is an issue with "choice."

I think that I see what you're hinting at here, so I will just say:

If I choose to have an abortion, it is my body, my choice. If, somehow, my choosing to have an abortion could cause other women around me to miscarry, then the choice would rightly no longer be mine alone.
