I'm not the smartest guy in the world but I used to work with Novell Network system (3.x, 4.x (eDir was fun!), 5.x, etc) and I treated the vaccines the same way I did with patching servers - I'd never immediately patch a server when a service pack came out but would wait a month or so to see the comments on various Novell boards while I tested the new SP on an isolated test system. Most of the time nothing would happen but a couple of times there would be a "...WARNING! Don't install SP3 because it breaks X and Y doesn't work well...." come across the lists.

I treated the Covid (non)vaccine the same way. It's new and there is no way in hell I was going to try it without waiting to see what happens. So I waited....even took two cruises towards the end of 2019 before I retired. On one cruise my cousin said "....I'm not sure what's wrong. I've got a temp of 100.5 degrees but don't feel bad...." but I never caught anything and never had a fever. Maybe I got lucky. Anyway after waiting and reading articles (some pro, some con) I made a personal decision not to take it. I'm one of only 3 people I know who didn't take vax but I am glad I skipped it.

Keep up the good work Karl.
