For mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (Unknown), the reporter did not provide any causality assessments.   She had no allergies and too many medical conditions to share. The patient did not receive any other vaccines in the 4 weeks prior to COVID-19 vaccine. The concomitant medication was not reported by reporter.  A redness on her arm, approximately the size of a tennis ball and resembling a hive, was observed. This itchy reaction persisted for four to five days, localized at the site of the injection in her right arm, with no other hives present on her body. She experienced this unusual reaction following her Spikevax vaccine, which began on the day of the injection and completely resolved within five days. Although her arm was notably itchy and she experienced some mild pain, it was not severe. Having never encountered hives before, she was concerned about the potential impact on her upcoming flu shot and was uncertain whether she developed an allergy to the Moderna vaccine, as this reaction was not listed among its side effects. The treatment medication was not reported by reporter.
