Free text: For three days following my second vaccine I had fevers, chills, extreme fatigue, body aches, headaches, nausea, extreme pain at the injection site that traveled the entire length of my arm (left arm for first dose, right arm for second) and dizziness. I had the same reaction following the initial vaccine as well. I needed a solid four days to recover from each injection and return to work.

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".
