DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Biopsy: results not reported Results not reported- Patient stated that the biopsy test did not determine what he was allergic to. For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments. Patient had no COVID infection in the past. His VAERS report number was 1914373. The patient did not had any other vaccines within 1 month of MODERNA COVID-19 vaccine. The rashes came on very easily. He went to a dermatologist, who prescribed him triamcinolone. They determined that his skin was hypersensitive. It seemed to clear up after 3-4 weeks, so he left it at that. It reoccurred a couple months later. He made another appointment in DEC 2021 because it seemed to be getting worse at that point. It was a constant battle between applying the cream, it comes back. He was concerned that it might be another issue. He gets mild itching now, but the rash have not returned in a noticeable way since. This case was linked to MOD-2022-528628 (Patient Link).
