Free text: I hadn't signed up for this until a few days after my first shot - so I wasn't able to report side effects I did experience the day of. Approximately 3 hours after the shot, I developed muscle aches that began in my lower back then quickly spread to legs, arms and shoulders - along with a low grade fever. This symptoms were very much "flu-like" and lasted about 4 hours (2 of which I slept mid afternoon from being exhausted by them). After those went away around 5pm, the injection site became very tender/sore and again around 10pm, the muscle aches came back. I took an aleve and promptly went to bed - by morning the symptoms were all gone.

Systemic reaction (other): I hadn't signed up for this until a few days after my first shot - so I wasn't able to report side effects I did experience the day of. Approximately 3 hours after the shot, I developed muscle aches that began in my lower back then quickly spread to legs, arms and shoulders - along with a low grade fever.

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".
