Free text: I did not feel good for Day 3 and 4 after the vaccine. I thought it was fatigue but ended taking my blood pressure and I was strangely hypotensive. 100/60 when I normally run hypertensive (140/90) with meds brining it down to 130/80. Same symptoms after the first dose. I have not checked my blood pressure today but I suspect it is still lower than normal as I feel mildly lightheaded

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".
