If its on the up and up then good.

They don't need to do a trial in humans to know it's potentially effective. They can test the effectiveness of the protein or whatever in a lab petri dish. Since they know the delivery mechanism and antibodies work in people, they can be highly confident their vaccine will work on the new mutations. Not 100%, obviously, but probably fairly close.
Moderna should be no different. It's basically the same mechanism with a slightly different delivery concoction.
No idea with Astrazeneca, but my guess is it and all the other vaccines will still work. As I understand these new variants, it's basically a sharper and/or longer sword the virus uses but nothing as far as "defenses" the vaccines target.
