So yeah, masks work in theory, but reality shown us they are completely useless, especially with newer more infectious variants. If they were such great invention we would not have flu and other respiratory viruses, in the end everyone will get infected anyway.
And during the pandemic, a lot of countries did indeed not have their usual flu season.

Page 5, new hospitalizations, 7 day numbers per 100K people in each group June 2022 unvaxxed 1.4/100K vaxxed unfinished 1.3/100K vaxxed 2 doses 0.5/100K vaxxed with booster 1.7/100K
To be fair most of these people are hospitalized for other reason than COVID regardless their vaccination as was always the case even when they were spreading propaganda about hospitalized unvaxxed. Numbers in ICU look better for vaxxed, but there are way too many factors to consider, you are more likely to have better life style as vaxxed risk group than unvaxxed risk group, which doesn't really say vaccination works.
