Free text: Two minutes after getting my first shot, I had a racing or rapid heart rate, and I felt this heavy feeling on my chest. I also had a knot in my throat, or at least it felt like this is what I had. This was not pleasant at all. I have also had this brain fog which has made it difficult to concentrate. The heavy chest feeling and knot continued and has not stopped. I am at day 7 and still having headaches and feeling tired.

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".
