"Reducing the spread of covid 19" is not a thing in the vaccine context. You are going to get it. Everyone is going to get it, probably repeatedly. France has vaccine passports out of the wazoo and 200k cases. "Reducing the spread" of something implies that the spread is actually reduced at the macro level. It's irrelevant whether a single vaccinated person has a slightly reduced probability of transmitting the disease if _in aggregate_ everyone gets it anyway. You may as well say that an umbrella helps prevent wet hair. Well yeah, but not in a blizzard. In a blizzard your hair is saturated anyway. No prevention has occurred. "Vaccinate the world" doesn't solve covid. Vaccinated populations still get and transmit the virus. They're much better off of course because the individuals fight off the virus more effectively and their health systems function better. But they still bloody get the virus, still provide a reservoir for mutations, etc. If I had a quid for every totally nonsensical proclamation about "solving covid via xyz" I'd be a billionaire.
