And that is exactly what a vaccinated person is. So why would we no longer have to
Without a test, how can you tell if you are healthy or infected with no symptoms?
Why do you need to know? What other pathogens do you regularly go get tested for if you are healthy or asymptomatic? Do you regularly go get tested for the flu during flu season just so you know? Measles? Strep? C. Diff? MRSA? Hepatitis? Tetanus? AIDS? RSV? Strep Pneumo? Legionella? etc.etc....
Re: “Asymptomatic - that is exactly what a vaccinated person is.”
That’s news to me. Asymptomatic, but infected, persons can and do spread infections to other people.
Re: “Healthy or infected without symptoms - Why do you need to know?”
Because it is not possible to create a useful epidemiology unless you know how many are infected, but not sick.
