MedDRA: Dizziness, Heart rate increased, Heart rate irregular, Immediate post-injection reaction, Palpitations — Feeling: Good · Site: Pain, Redness · Muscle or body aches

Free text: Within a few minutes of injection I experienced light headed ness, rapid heart rate fluctuating between 85 bpm to 145 bpm. This came in waves for up to 25 minutes. Gradually subsiding. Im currently being treated by a cardiologist for heart palpitations, occasional rapid heart beat. So, what I experienced directly after the shot was a little more profound than my usual occasional irregular heartbeat.

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".
