There was a time when Fauci told us the vaccinated wouldn't transmit the disease. His blind followers believed him in obedience to the governmental issued "science." Are you and your banned relative back to sharing beers?
I keep saying this, but I guess I have to keep saying this until it sinks in.
The super-sensitive COVID tests became so good at detecting virus, even in trace amounts, that they became a surrogate for people saying "I have COVID!" when they really simply tested positive for having been exposed to the virus, often times with no manifestations of the disease whatsoever.
What would have happened if, 70 years ago, you are in an area with a polio outbreak and had gotten a polio vaccine? You would have found out that it protected you, completely, from getting the disease. You never got sick.
But what if 70 years ago there was also a super-sensitive polio vaccine test that was so good at detecting virus, even in trace amounts, that they became a surrogate for people saying "I have polio!" when they really simply tested positive for having been exposed to the virus, with no manifestations of the disease whatsoever, because the vaccine allowed them to fight it off???
Vaccines work. For polio, smallpox, and yes for COVID-19. They work pretty much in the same way. Are they 100% failproof? Of course not.
