Free text: I was a little cold when I woke up for about an hour, later in the afternoon I got just a little warm and sweaty for no reason. It lasted about a half hour. I took my temperature during that time and it was low so I didn't have a fever. It may have not been related tobthe vaccine at all becuase I am pregnant and sometimes I get brief hot flashes.

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".
