No less than three anti-COVID vaccines are on the horizon, though approval--and more importantly, distribution--will take time. Access will differ by region and country.
Until V-Day arrives worldwide, office building managers have a problem: We need to get the economy going, but how do you pack a tall building with workers who would rather not die when the cure is so close? Elevators are the big problem, as they're a great way to breathe someone else's air. That's why a hospital in Thailand has been asking people to ride elevators in this odd-looking manner since March:
It's a lot cheaper for building managers to slap these stickers on than to retrofit expensive ventilation/air purification systems. And if I had to ride in an elevator I'd adhere to this--even though there are no published scientific figures on how much protection this confers.
Heck, I can name at least three socially-awkward acquaintances who would probably prefer to ride elevators this way, even after the pandemic is over.
