Yeah I remember being in the airport in January 2020 a week after starting a new treatment regimen for an autoimmune condition consisting of high dose intravenous steroids, and emailing my doctor that I was masking up, "But I'm sure that thing from China isn't over here yet."

Hindsight: yes it was. It was definitely everywhere already, just most of the people exposed weren't getting deadly ill.

Similarly, I am all over those vaccines. I don't have room for a bad bout of Covid in my life.
