Where does this idea that a vaccinated person could still be carrying COVID come from? Whenever you dig into the details of this concept, it comes from the fact that a rigorous study of asymptomatic COVID transmission among vaccinated participants was not a part of the Phase 3 study. In other words, we cannot *prove* that COVID *doesn’t* asymptomatically tag along for the ride in a vaccinated person.
When it comes to transmitting COVID to another person, a mask is only helpful for airborne transmission. That means the virus would have to be coming from your upper respiratory tract for a mask to be effective at stopping it. But if there is enough COVID virus in your upper respiratory tract for you to be transmitting it, then there is enough COVID virus for a testing swab to detect. In essence, if you had enough virus in your exhalations to infect another person, you would be testing positive for COVID… which is exactly the observed measurement that the vaccine prevents.
