That's an interesting quote and you're 100% correct. However you only gave a snippet of the quote. The full transcript is:
Commentator: If the Trump administration approves a vaccine before or after the election should Americans take it? And would you take it?
Harris: If the public health professionals, if Dr. Fauci, if the Doctors, tell us we should take it, I'll be the first in line to take it, absolutely. But if Donald Trump tells us that we should take it I'm not taking it.
Harris is alluding to the fact that we should listen to people who actually have medical experience and know what they're talking about. You have to remember this was only a few months after Trump had tried to play doctor on TV by saying:
"So I asked Bill a question some of you are thinking of if you're into that world, which I find to be pretty interesting. So, supposing we hit the body with a tremendous, whether its ultraviolet or just very powerful light, and I think you said, that hasn't been checked but you're gonna test it. And then I said, supposing it brought the light inside the body, which you can either do either through the skin or some other way, and I think you said you're gonna test that too, sounds interesting. And I then I see the disinfectant, where it knocks it out in one minute, and is there a way you can do something like that by injection inside, or almost a cleaning. Because you see it gets in the lungs, and it does a tremendous number on the lungs. So it'd be interesting to check that. So you're going to have to use medical doctors, but it sounds interesting to me, so we'll see. But the whole concept of the light, the way it goes in one minute, that's pretty powerful."
