Decoding COVID-19 Had posted about it in the coronavirus thread. Was a good episode. Some of the info at the beginning you might already know if you’d been keeping up with COVID-19 news. I didn’t know much before RNA vaccines and how quickly they go bad/become ineffective. Was interesting to see a bit more about Wuhan’s green/yellow/red code system, QR code scanning that incorporates contact tracing closer to the end. That along w/the temperature checks are WAY more strict than anything else we have in the US now.
