MedDRA: Brain fog, Disorientation, Paraesthesia oral, Swelling — Feeling: Good · Be unable to work

Free text: I wanted to report what happened the day of the second shot. Within 30 to 40 minutes of the shot, my tongue started tingling. I dont think it swelled. If it did it wasnt much. Within 45 minutes of getting the shot i started becoming disoriented. Trying to drive back to work became very difficult. I couldnt recognize where i was. I sat in car outside work for about 10 minutes and decided i was getting progessively worse. I could barely walk and i could not think straight. It was as if i had been drinking alot. My arms and legs would not work properly. That lasted almost 2 hours then i started getting more use of my limbs. No symptoms since the day of the shot

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
