Northeast Asia has a masking rate of over 99%. I've corresponded with numerous people in Japan and Korea over the past 2 years and anecdotally I have heard that the mask rate is 100%.
Here are SK's numbers:

See the spike? That is with almost 100% masking.
Here are Japan's numbers:

What's that? Another spike?
I'm not going to say masks don't work, but one must ask themselves what exactly does the word "work" mean? I suspect it may reduce your odds of catching the Germ by some very small percentage. So tell us, what do people mean when they say "masks work?" If your kid is in a crowded classroom with a piece of cloth embroidered with a my little pony logo strapped to his face and the kid next to him is blowing hot for 6 hours, that mask isn't gonna do shit.
Same question with the vaccine. Thankfully, we were given a definition of "efficacy" at the outset. Initially, it was said that it was "95% effective." Do you remember that? How did they define efficacy? Well right here in the Pfizer report to the FDA they said "The primary efficacy endpoint is incidence of COVID-19 among participants without evidence of SARS-CoV-2 infection before or during the 2-dose vaccination regimen."

Thankfully people are easily distracted by shiny objects and were able to be quickly reprogrammed into thinking "efficacy" equals "reduces severe cases." Ultimately, in circumstances like this the real time data is usually shit, which it is here. The safety and efficacy of the vaccine is something that will require a long period of observation. I would not say it is not effective, but I would say it is certainly not "effective" as it was originally defined. However, even that requires a caveat. It may actually be totally effective against the original variant, but the problem is coronaviruses mutate very quickly, and that certainly appears to be the case here, as the most recent variant seems to have been "more transmissible" and "less virulent."
You see, in real world data sets there are a number of variables at play, but the media and government have reduced everything to a single variable model. They also speak in absolutes, which concerns me. When you speak in absolutes about a rapidly evolving situation while dealing with imperfect information it makes me question if you are actually smart. It's like the people who were certain of what happened in the Duke Lacrosse case the moment the story broke. Or when Jussie Smollet got attacked by those Trump supporters.
