Free text: These symptoms are from Monday February 8th, the day after my vaccine. They lasted all day. Fever gone Tuesday and just slight tiredness residual. I had hives the evening of the vaccine and attribute them to foods I ate which I am mildly allergic to. Although the hives were mildly worrisome, I assumed they arose due to my busy immune system just after the second vaccine. I have since made an appt to have allergies tested. I hadnt had any hives in years from food reactions.

Systemic reaction (other): These symptoms are from Monday February 8th, the day after my vaccine. They lasted all day. Fever gone Tuesday and just slight tiredness residual. I had hives the evening of the vaccine and attribute them to foods I ate which I am mildly allergic to. Although the hives were mildly worrisome, I assumed they arose due to my busy immune system just after the second vaccine. I have since made an appt to have allergies tested. I hadnt had any hives in years from food reactions.

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".
