Kevin,
The link is missing from your reply. Nevertheless...

I think you missed my point; let me present in a different scenario:
A person immune to a coronavirus inhales a virus load (who knows what strain). 5 min later the same individual sneezes. The inhaled virus is still active because the virus has not achieved a replication level to trigger a response, or the immune system did not have the chance to annihilate it yet, or the immune response is just enough to not make one sick, but the individual is still infectious. In other words, you don't get the fever 5 minutes after you get exposed, but for some time after exposure you're a carrier. I am not sure about the exact time intervals, but you get the idea.
Also it's not certain how long the vaccine protection lasts. The best vaccine is advertised as 95% effective against getting sick.
In the context of 55K+ new infections daily, or until a sufficient part of the population is immunized, it's better to keep the spreading at the minimum.

>Months ago, was anyone in the CDC saying that with the vaccine, after you've produced antibodies, that someone could get enough viral load to replicate to the point of being contagious to others, but without getting seriously ill yourself????

Are you aware that the infectious state occurs before symptoms are developed? Or that asymptomatic people can be carriers?
Months ago, when the vaccines were not available, I have not heard anyone say that people who achieved immunity from prior infections should stop wearing a mask. What's making the vaccine different?

>It is unfortunate that no one seems to be challenging Fauci on this: how can a virus not enter the cell and replicate enough to make you sick but can do so enough to make you infectious??? (Sadly, Rand Paul, who supposedly is a physician of sorts, really screwed up the question)
>Bottom line: vaccination programs do not accelerate mutations. (If that were true, the history of smallpox and other diseases would sure as hell be different)

I think you're misunderstanding again. The vaccinations do not accelerate mutations and I have not heard anyone say that. But intense replication does create an opportunity for mutations to occur. Mutations are dependent on the conditions in which replication occurs. If the vaccine provides protection against *some* strains, that means that the strains less targeted by the vaccine have a better chance to develop. I see new flu vaccines being developed every year. I'd wonder why?
