@joeinwynnewood @GreySkies @augieray Against R₀ ≅ measles current circulating variants, you want a continuous, well-fitting, elastomeric gasket against bare skin. (Block the filters and inhale and the mask crumples but does not leak as you hold the inhale.)

COVID has evolved; what was more than sufficient against the wild type is not necessarily sufficient today.

COVID brain damage mechanisms that are inescapable and permanent are now known in detail. I'd stay off the flight.

@joeinwynnewood @GreySkies @augieray If you want some home empiricism, finish sand—meaning use a fine grit—a lot of pine in various masks and see what's in the mask at the end of the day.

Elastomerics got created in industrial contexts for a reason. Simple disposable masks, even N95s, tend to leak if you move your face much or after twenty minutes and the nose bridge doesn't hold its shape. That's because they have to be cheap enough to be disposable.

Elastomerics work better and cost less.

@graydon @GreySkies @augieray
The real question is whether or not near 100% filtering of airborne virus is required to prevent infection.
I'm hard pressed to believe this is the case when current (administration within past 6 months) on the latest vaccination formulation (bivalent as of now).

@joeinwynnewood @GreySkies @augieray Today, mRNA vaccines somewhat reduce your risk of death. The decreased odds of becoming infected due to vaccination are gone by month three, and were never grounds for confidence. See lookerstudio.google.com/embed/ (From covid19resources.ca/covid-haza under "Infections", top of the right hand column.)

With COVID, brain damage is certain once infected. Better to not get infected in the first place. Get vaccinated, but emphasise air quality and the best respirator.

First, I've had 6 vaccinations, that chart only goes to 4. Second it says nothing about the degree to which vaccination reduces the likelihood of infection in public spaces.
Lastly, your statement regarding brain damage is highly suspect. The possibility certainly exists as is the case with cardiovascular issues, but certain damage?
I very much doubt you can find a quality study that makes such a definitive conclusion.
Air quality and high quality masks? Of course.

@joeinwynnewood @GreySkies @augieray You might want to look for "COVID neuron fusion"; you might find the university press release uq.edu.au/news/article/2023/06 or the paper, science.org/doi/10.1126/sciadv interesting.

(There is of course nothing to say this is the only mechanism.)

As for vaccination; those figures give the odds of infection on exposure. Where the exposure happens isn't relevant.
