Free text: During the night, I woke up with my legs jumping- like chills, but I wasn't cold. Only lasted about an hour- muscles behind my legs were felt tingly and flu-like, but I could control it. It went away after about an hour and I went back to sleep. This morning, I felt fine-my arm where I got the injection feeling better too.

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".
