Per President Biden we will have enough vaccine to have incoluated everyone by the end of the summer. Which vaccines is that?

The one(s) that do nothing to mitigate the South African more deadly strain that is ripping through the world twice as fast as the original iteration and is more deadly?

Or the original vaccine(s) developed for the first strain of the original COVID 19?

Anyone know? I haven't heard or read anything about the gubment addressing THAT ISSUE. Have you?
