It's neat that there are some parallels between how viruses propagate through communities of hosts and how virus cells propagate through each single host. At both the hosts' cellular and community scales, early recognition of the virus is crucial. I've been wondering how well-constrained the amount of exposure optimal for a human vaccine is. There are already many papers incorporating, for example, the concept of a viral dose for covid-19, but I didn't see any that provide a quantitative estimation for a vaccine as the primary aim of the study. So yes, it's still quite unknown, I guess. Maybe there's something in peer review right now from China? Ugh, this really has been an inversion of American influence in the scientific community. Shit, guys. We blew it. The story of NYC right now will be the story of many more places within days. Stay safe, some of you are in an emerging "badzone", to be technical. And then there's kleinbl00, who may have already downloaded the covid-19 firmware update.
