Gattaca. I’m curious tho where does it stop. For example, US stopped TB vax long time ago while half of EU continues. Those born in EU bear the scars on their arms from the vax. Sure TB isn’t as prevalent in the US as it used to be but there’s nothing stopping it from coming on a plane.

Bacterial infections of the lungs are very hard to fight esp with the increase of antibiotic resistance. A single cough from a TB infected individual used to be a death sentence to the receiver (prior to antibiotics).

So where does all this start and end. If we are serious about health while traveling then let’s go all in across the germ spectrum and see what happens ;-)

I’d love to see planes reporting on cabin air quality as well. I’m sure I’m not the only one who gets sick (pre Covid) when traveling long haul.
