They will work fine because this virus can't evolve for shit. It's only produced 2-3 strains and only has one external protein it can mutate. The current vaccines are still good enough against it, and it doesn't take long to edit an mRNA vaccine either.

This math is wrong, you should think of it as getting a flu but ten times worse that also gives you a permanent heart condition. And remember that the flu is already ten times worse than you think it is, because the last thing you thought was a flu was just a cold.
