Free text: So - I had this new symptom yesterday and today. I didnt report it yesterday, because I thought I had slept funny. I have a very stiff neck on the side where I got the shot. Feels like a pinched nerve in the upper trapezius - and there is pain that shoots up from there. I feel it when I turn my head to the left and right. I dont know if this is Moderna caused?

Free text: Happy to report that the pain in my trapezius/neck is all but gone. Just a little twinge l, but I can turn my head side to side almost normally. Again - hard to say whether this is pulled muscle or a symptom of the shot.

Free text: I got Covid arm after the first shot - about 13-14 days after the shot. It seems I have the same kind of thing, but it is immediate after the 2nd shot. Likely, I have a mild allergic reaction to something? Just very lightly itchy - red splotches come and go.

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".
