Maybe you should have read the entire interview instead of seizing on a media morsel. Vance made his position crystal clear.

Excerpt:
“I think in Texas they’re trying to make it easier for unborn babies to be born,” Vance said in the Spectrum News interview. “There is a view, common among leaders of the Democratic Party, that babies deserve no legal protections in the womb. That is a common view in the Democratic Party, and all I’m saying is that view’s wrong.”

Jackson asked Vance whether anti-abortion laws should include exceptions for rape or incest.
Vance replied: "Look, I think two wrongs don't make a right. At the end of day, we are talking about an unborn baby. What kind of society do we want to have? A society that looks at unborn babies as inconveniences to be discarded?"
Jackson tried to get Vance to comment directly about exceptions, asking "should a woman be forced to carry a child to term after she has been a victim of incest or rape?"
Vance replied: "My view on this has been very clear and I think the question betrays a certain presumption that is wrong. It’s not whether a woman should be forced to bring a child to term, it’s whether a child should be allowed to live, even though the circumstances of that child’s birth are somehow inconvenient or a problem to the society. The question really, to me, is about the baby. We want women to have opportunities, we want women to have choices, but, above all, we want women and young boys in the womb to have the right to life. Right now our society doesn’t afford that and I think it's a tragedy and I think we can do better."
