Aaaand, so what? It is, at worst, the ordinary flu.
CDC is kinda making sense here — which probably means that the world is about to end.
Now that even the dummies have been shown that the vax did not confer any ability to stop spreading the infection you might as well mix with others as soon as you can.
It is a respiratory virus. Not unlike any other. There is no protection except your immune system, and the vax did nothing to improve that. Nothing a’tall.
The CDC was not prepared for a pandemic and had no idea what it was doing. They made it all up on the fly.
