MedDRA: Chills, Eye pain, Fatigue, Headache, Nausea, Neck pain — Feeling: Good

Free text: The night after my second vaccination I had a sick stomach, chills from 2-4 am, and a headache that was focused behind my eyes, at my forehead, and in my neck. The issues resolved within 24 hours of my vaccination, except the headaches and nausea (in much milder form) lingered until about 36 hours after the vaccination, along with some fatigue. By 48 hours, all issues were resolved. Thanks (b)(6)

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".
