COVID Vaccines - Is That a Good Thing?

I've been hoping that, and watching Israel in particular, there seems to be some indication that they've got the vaccinations ramped up. And I keep hoping that the vaccines are, there's enough of them and they're getting out there fast enough so that we might be able to keep the bug under control. But it is only beginning to dawn on us that new mutants that are harder for our immune systems to recognize are essentially a certainty. The key to ever regaining control is to ensure that when these things arise somewhere, they don't immediately find their way around the globe.
