There is the finding that naive immunity did not differ from already once infected immunity where as the vaccinated immunity did not differ from the unvaccinated immunity although the tendency is very clear: vaxxed immunity is less effective in all comparisons. That means the study did not only falsify that vaccine immunity against infection is stable over time but also falsified that unvaccinated immunity is worse in preventing infection. Now you could come up with confounders like age, and collinearity of calendar time to vaxx status and vaxxed/unvaxxed ratios but they actually corrected and interpolated for these factors. The conclusion that immunity was taken away is not legit because it was not the question here but the signs are quite strong since this study adds up to existing data in regards to cross-immunity and the infection numbers. e.g. since testing of vaxxed and unvaxxed became somehow equivalent in Germany again, there are exponenrial rising numbers in the vaxxed but not in the unvaxxed. So that we have a linear grow curve since a couple of weeks. In Berlin at Charite university hospital they found that nurses with cross-immunity had significantly less often bad sickness after infection. And there are many studies that have shown cross-immunity in vitro. All in all, we have to admit that the crisis is more severe than last year in infections terms despite high percentages of vaccination.
Basically, both of you are wrong.
