Survey response — days 1–6 daily, dose 1
MedDRA: Dizziness, Dysgeusia, Immediate post-injection reaction, Paraesthesia, Presyncope — Feeling: Good · Site: Pain

Free text: 5 minutes after vaccine I sensed a momentary metallic taste, then a sudden rush of severe dizziness where I thought I might pass out. That ended in 10 seconds then I felt a cool tingling feeling throughout my chest which dissipated within moments and Ive been fine since- scary. I always tolerate needle sticks and procedures fine and it didnt happen until minutes later so I dont think it was a vasovagal response to anxiety (Im an RN)

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".
