I think we are still confusing the two different claims that you "cannot catch COVID-19 twice" versus catching covid twice AND spreading it to someone else. We still don't have evidence of a reinfection *spreading* it to someone else.
We're not confused. CDC is. You don't catch COVID-19. It's a disease diagnosis. CDC still has everyone confusing "PCR Positive" with "disease diagnosis". So, to break it down: people are testing positive for a long time following SARS-CoV-2 virus. So some people will test positive twice due to one infection. The first "Case" will likely have not been COVID-19 due to false positives on the PCR. Also, to spread the virus, you need high viremia. While everyone can be infected again, only those w/out sufficiently broad immunity can spread the virus. So, people who are "sick twice" probably didn't have COVID twice, and people who are vaccinated have as high viremia in the nasopharyngeal tract as the unvaccinated who never had a SARS-CoV-2 who are newly infected, but those who have natural immunity do no develop high viremia, so are unlikely to "get sick" (i.e, have COVID-19 disease), and are also unlikely to spread SARS-CoV-2. Hope that clarifies. CDC's terminology is as clear as mud.
This is worthy of a separate post, if you can elongate it a little. Sometimes people need concise explanation in plain words to reinforce all the data and "science" they are fed.
Interesting points. I tend to think it's the flawed use of PCR testing that has been amplified way too high and would thus pick up viral fragments (antigen footprint) remaining in the body for several months post-illness. It can also pick up viral fragments of any other virus you may have had in the recent past.
There are plenty of studies showing that unvaxxed can get reinfected. The good news is that it's usually not severe.

Thank you. Very helpful.
