Get vaccinated BEFORE getting infected
Since, like yourself, I got COVID-19 after three doses of vaccine, I'm also encouraged to read about the synergistic immunity. (I just coined that phrase. I want credit!)
I do wonder if the study you cite said anything about duration of the immunity. For example, my current plan is to get a fourth shot (I'm over 50) before Worldcon in September. Will I need it by then?
Speaking of which, any chance you'll be in Chicago?
Consider using the term "volunteers" instead of "subjects" for clinical trial participants. (from a retired nurse practitioner and science writer with clinical research experience and strong opinions about word choices).
