My reaction to "we still need to wear masks after vaccination" is "why are you wearing a mask?"

If the answer is "so I don't make unvaccinated people feel like second class citizens" then fine.

But if it is "you could transmit COVID after vaccine immunity" that is nonsense

Masks prevent respiratory transmission

If you are expelling enough COVID virus to make someone ill, then your respiratory track *will* be testing positive for COVID

That is exactly the thing that the vaccine prevents. That is how we measure the efficacy of the vaccine

If you see "experts" telling you that you need to wear a mask after vaccination b/c you could still transmit the virus, what they are really saying is "we're worried about social stability if a class of people can go unmasked but we're not allowed to make that our reason"

My god

This is one of those things that is so obvious that only really smart people who talk themselves in circles until they believe anything can think it's not true

Think hard and walk through the process of vaccination, what it does, how we measure it, how respiratory infections work, and how masks work.

Then go back over what you've heard about post-vaccination mask-wearing and ask how it makes sense.
