I have a suggestion for you if you want to try again with this friend, or try with other people you know. Check out Alexandra "Sasha" Latypova. She's an artist with some lovely paintings online, but she's also a former "insider" in the vaccine manufacturing and regulatory world. She's done some really interesting investigation re: the Pfizer and Moderna vaccines, including manufacturing practices and glitches that help explain why some lots of the vaccines produce many adverse events, and other lots very few. Dr. Peter McCullough did an excellent interview of Latypova and I'll give you a link. (BTW, one of the things she explains is the magnetism on the injection site that some people experienced.) Maybe this interview would open the door to some interesting discussion with your friend . . .
