Free text: I was very sick after the first vaccination. I had fever, chills, be headache, stomach cramps, diarrhea, and rapid heart beat 6 hours after the shot. I am very nervous about the second shot, especially because of rapid heart beat since I have high blood pressure. I have heard that the Moderna shot is making more people I'll, compared to the Pfizer vaccine. If this is true, I would have waited to get the Pfizer.

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".
