Free text: Systemic reaction (other): Hives.... hives everywhere! With a heavy combination of Pepcid and Benadryl I have finally been able to regain some sense of normalcy... although the Benadryl makes me feel like a zombie. I contacted the CDC myself and was told I am not to get the 2nd shot. Im now looking for a doctor for allergy testing to see if Im able to get J&J.... today is the first day that the hives have not spread... a week after my shot... this is awful · Healthcare visit (other): I recently moved out of state so I have been looking for a doctor in the area that can see me and takes my insurance. Seeing that its still a pandemic and most doctors arent taking new patients, this process has been absolute hell. I am going to go see a doctor when I can as the CDC said I am not to get a 2nd dose or any other shot until I have visited a doctor and have been allergy tested. No vaccine.... NO VACCINE has EVER caused me a reaction like this... it sucks

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".
