Free text: About 12 hours after the second vaccine I experienced fatigue, myalgias, weakness, subjective fever, chills. Resolved with 1g Tylenol and 5 hours later 400mg ibuprofen for muscle aches. The weakness was interesting - I couldn't open the Tylenol bottle. Didn't feel like flu body aches. And my backpack felt very heavy walking into 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".
