Sounds like they work for colds then. But frankly we’ve probably all had COVID whether masked, vaxed on not.

The world had essentially no influenza season, 2020. This isn't just the US, it was everywhere. Some strain(s) may have gone extinct: https://www.nature.com/articles/s41579-021-00642-4

Let's see, masks work against rhinovirus, influenza virus, and they magically don't work for (also respiratory) COVID? Doubt it.

What possible evidence do you have for this "all had COVID" assertion? The biggest estimate I could find was 140 million in the USA: https://www.washingtonpost.com/health/2022/02/28/covid-cases...
