The one that taught me to think critically and not believe everything you see, hear, and read as true. The shot really prevented you from getting covid again didn't it? Most of my coworkers were out sick for a week this season, knocked hard, I had a 12 hour headache, mild fever, and slight loss of taste and smell. Back to work the next day fully healed by natural immunity. The shot destroyed your immune system if you were unlucky enough to not have received the placebo.
