Hello,

I thought you might find this post interesting. It touches on some of the challenges of developing an effective vaccine (e.g, the lethality of COVID-19 is the result of an overzealous immune response that basically kills the patient — this may have something to do with SARS CoV-2’s bat lineage). This is a long post so skimming allowed! https://medium.com/@trackernews/underlying-conditions-bad-worse-and-next-for-covid-19-a-few-words-about-bats-advice-43402e979ce3
