There are some interesting theoretical models to explain the second major wave without mass reinfection, but they require a lot of assumptions to all fall perfectly into place (population demographics, movement patterns, etc.) for this to even be possible. There’s a preprint paper discussing how that could work here:

However, given the structural changes to the S protein in P.1, significant reinfection primarily focused on those with mild or asymptomatic previous COVID-19 infection remains - by far - the most likely reason for what took place in Manaus and other areas.
that’s a nice new tagline you’ve got going on there...
how about you practice what you’re preaching in it...
Though I’ve seen anecdotal reports and reports in trials and studies, I’ve never seen a report by the CDC of prevalence of hospitalizations (or severe cases or deaths) in vaccinated vs in unvaccinated in the real world.
I think that would be very useful and easily determined.
Maybe I’ve just missed it but I have looked hard.
LOL...from your article....
“Indeed, a population sero-prevalence study in 133 Brazilian cities including Manaus found a much smaller (∼20%) sero-prevalence in July-August, 2020. Hence, the blood donor data in Manaus are most likely biased and/or their analyses are flawed”
From the CDC website...
“A positive test result shows you may have antibodies from an infection with the virus that causes COVID-19. However, there is a chance that a positive result means you have antibodies from an infection with a different virus from the same family of viruses (called coronaviruses).”
I actually believed you were serious.
How can you possibly believe that someone can be re-infected by a “variant” but can’t be re-infected with Covid after SARS?
In all three of those articles there is a whole bunch of guessing, inferring, extrapolating, etc....but not once does it show an example of someone getting sick, testing positive for COVID, recovering, getting sick again and testing positive again. You would think they could at least find one example in that town to mention in the articles.
