Sorry, but I think people are being overly optimistic about these vaccines. I'm not saying I believe they won't be effective, and I will take whichever one I can get. I just don't believe they will return the world to March 1, 2020, and I think I hear too many people talking like they think they will. New virus variants may just take us back to square one. At the very best, I expect we will need to get shots for coronavirus every year, just as we do flu shots, and that's no so bad.
I have been wrong before. When the first HIV medications came out, I expected they would be effective for about five years, and then they would cease to work. Fortunately I was wrong, and new medications were developed and are still being developed. Now we even have PReP.
