I wonder what would happen to the profit stream if the vaccines caught up to the viruses and actually became highly effective? It’s almost as if the flu, and now Covid, are cash cows.It's not unlike our current flu shots every year......some years the shots seem to match up well with the variants that we see, and other years (like this year) the shots don't do squat to help fight against the variants that show up. The more quickly the viruses mutate, the less chance that the shots are going to provide protection. They're constantly chasing their tail. Nothing new here.
