it's most definitely not. The application and collection points aren't even the same because there's a time delay in antibody testing.

There are people I am personally acquainted with who have been PCR positive for COVID, who are now also receiving the vaccine.

If they haven't been proven to be infected why should it matter?

What? They have been proven to be infected (PCR positive) and they are now receiving the vaccine.

PCR positive doesn't mean infected.

You'll need an high amount in PCR, i.e. low cycle threshold for the probability to be high.

Antigen tests will show if there was/is an infection.

PCR does not show infection only presence. (WHO has now put out guidance about this. They don't have to it's well known.)

If you're European this may be strange to you but I'm the U.S. we don't receive the cycle count when the RNA for the virus is detected.

Here's Fauci talking about it a little: https://youtu.be/a_Vy6fgaBPE&t=4m30s

Simply tell people, "if you've had COVID, don't get the vaccine" or maybe "go to the end of the line"

That’s terrible messaging given that reinfection is rare but possible and occasionally deadly. We want everyone to take it.

Hard to imagine that infection and recovery from the actual virus confers less immunity than the vaccine, but even without knowing that, it seems reasonable that people who have already recovered should be a lower priority for vaccination than more at-risk groups.

It’s not hard to imagine, it’s a well observed phenomenon in other diseases like HPV. Antibody titers were higher for the mRNA covid vaccines than convalescent plasma if I remember right.

Most people probably are at lower risk, but some people are dying from reinfection. They certainly weren’t.
