I was vaxxed by having the actual virus integrate its RNA into mine last Christmas. Made me sick for a few days and no taste or smell for a couple of months.
Had some pretty good exposure since a few times with the latest being 3-4 weeks ago working cattle beside a guy that didn't tell me he was running a fever and tested positive the next day. So far antibodies appear to be holding up for me.
Same for my daughter, whose room mate was sick for 3-4 days before getting tested.
