Free text: I had my second vaccine 2/19. The symptoms were the same as the first vaccine just more intense. Although, with my second vaccine I experienced pain on the left side of my chest. It was odd because the pain went to my left arm. It wasnt joint pain. My concern was I had an enlarged heart with fluid last year from a virus. It was treated, and hopefully recovered. The chest pain lasted a few hours.

Systemic reaction (other): I had my second vaccine 2/19. The symptoms were the same as the first vaccine just more intense. Although, with my second vaccine I experienced pain on the left side of my chest. It was odd because the pain went to my left arm. It wasnt joint pain.

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".
