I don’t think he’s conceding - he keeps saying it’s going to happen and be great while scientists are still saying they don’t know if this is even a vaccine-preventable disease. He is placating the left so they can focus on the vaccine instead of developing another goalpost.

I'm not conceding at all, I just know that if it gets developed that will be forced to reopen everything. In the mean time, I will continue advocating for everything opening right now, and if a vaccine does arrive I'll let whoever wants to be a guinea pig to take it
