I think pro-life supporters would argue that abortion leads to the death of the unborn child, who they believe has a right to be born. Is a woman required to carry an unwanted child to term because the fetus has rights? Is a Canadian trucker required to receive an unwanted vaccine to protect the old and vulnerable? Personally, I see a lot of similarities in the ambiguity of where the boundary exists between the rights and responsibilities between two parties relative to each other.
