GOOD NEWS! A UNIVERSAL sarbecovirus vaccine candidate has officially started clinical trials! GBP511 is the FIRST vaccine to reach human testing that is intended to protect against MULTIPLE strains of SARS-CoV-2 as well as other related coronaviruses with the potential to spark dangerous outbreaks.

This is an amazing post to pick out all the Russian sockpuppet accounts. If it starts with a "I am member of LGBTQQQ+ leftist atheist autist and <what about ...>", there's your cue.
Is anybody ever gonna take a step back and realize the "Russia Russia Russia" people — derided as lunatic wine moms — were actually underplaying the foreign influence stuff, and the loud people who kept insisting it was all fake are now saying Jeffrey Epstein was kind of a cool guy?

The risk of the airborne transmission of disease correlates with the amount of infectious exhaled aerosol. Since people exhale CO2 with aerosol, its conc has been used as proxy for exhaled aerosol
