Free text: First of all, I am a very healthy and well educated male, never had any allergies. I never had any kinds of COVID test, and never had any COVID like symptoms. I got the second dose on May 6th at 1:45 pm. Except normal flu like symptoms, I had a really bad uncontrollable body shaking on May 7th at 3 am for about 30 minutes. I have never experienced this in my life, it was like constant chill shaking, but its much more severe. It was indeed uncontrollable, no matter I lied in bed or sit or stand, and it was actually shaking, very dramatically, and its throughout my whole body. I was almost to call 911 during that time, it was extremely unpleasant, but seemed to relief after 30 minutes. Please investigate, not just for me, but for human beings. Im sure that Im not the first one had this unusual reaction, but I shall not be the last. Thank you.

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".
