On 16-Feb-2021, the patient experienced VACCINATION SITE WARMTH (Warm reddened skin/self diagnosed warm red rash on upper left arm/warm reddened skin with slight bumpy rash appeared) and VACCINATION SITE PRURITUS (itchy at the injection site/Itching). 16-Feb-2021, the patient experienced RASH PAPULAR (Bumpy rash/ slight bumpy rash appeared) and VACCINATION SITE ERYTHEMA (Itchy red rash at injection site/self diagnosed warm red rash on upper left arm). 16-Feb-2021, the patient experienced VACCINATION SITE RASH (rash at the injection site/self diagnosed warm red rash on upper left arm/warm reddened skin with slight bumpy rash appeared). On an unknown date, the patient experienced SKIN LESION (Chilblain-like lesions) and MYALGIA (Muscle aches). On 28-Feb-2021, VACCINATION SITE WARMTH (Warm reddened skin/self diagnosed warm red rash on upper left arm/warm reddened skin with slight bumpy rash appeared), RASH PAPULAR (Bumpy rash/ slight bumpy rash appeared), VACCINATION SITE PRURITUS (itchy at the injection site/Itching), VACCINATION SITE RASH (rash at the injection site/self diagnosed warm red rash on upper left arm/warm reddened skin with slight bumpy rash appeared) and VACCINATION SITE ERYTHEMA (Itchy red rash at injection site/self diagnosed warm red rash on upper left arm) had resolved. At the time of the report, SKIN LESION (Chilblain-like lesions) and MYALGIA (Muscle aches) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In 2010, Catheterisation cardiac: unknown (Inconclusive) unknown. On 11-Sep-2020, Biopsy breast: unknown (Inconclusive) unknown.     The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) was unknown.   For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter considered VACCINATION SITE WARMTH (Warm reddened skin/self diagnosed warm red rash on upper left arm/warm reddened skin with slight bumpy rash appeared), RASH PAPULAR (Bumpy rash/ slight bumpy rash appeared), VACCINATION SITE PRURITUS (itchy at the injection site/Itching), VACCINATION SITE RASH (rash at the injection site/self diagnosed warm red rash on upper left arm/warm reddened skin with slight bumpy rash appeared) and VACCINATION SITE ERYTHEMA (Itchy red rash at injection site/self diagnosed warm red rash on upper left arm) to be possibly related. No further causality assessments were provided for SKIN LESION (Chilblain-like lesions) and MYALGIA (Muscle aches).    On 20-FEB-2021,  patient stated she still had rash but it was not itching.
