On 20-Aug-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 20-Aug-2021, the patient experienced PRURITUS (Itching below the inject site), VACCINATION SITE ERYTHEMA (Arm was red), VACCINATION SITE SWELLING (Arm was swollen/Expecting the "usual swelling and tiredness" but, "it was more than that, it was worse"), DECREASED APPETITE (Lost her appetite), WEIGHT DECREASED (Weight loss), ILLNESS (Felt very sick/badly), RASH (Developed a rash below the injection site), NAUSEA (Very nauseous) and FATIGUE (She was expecting the "usual swelling and tiredness" but, "it was more than that, it was worse".).

On an unknown date, the patient experienced MOBILITY DECREASED (Can't walk or move around). The patient was treated with AZITHROMYCIN for Inflammation localized, at an unspecified dose and frequency and PARACETAMOL (TYLENOL) for Erythema, at an unspecified dose and frequency. On 31-Aug-2021, PRURITUS (Itching below the inject site), VACCINATION SITE ERYTHEMA (Arm was red), VACCINATION SITE SWELLING (Arm was swollen/Expecting the "usual swelling and tiredness" but, "it was more than that, it was worse"), DECREASED APPETITE (Lost her appetite), WEIGHT DECREASED (Weight loss), ILLNESS (Felt very sick/badly), RASH (Developed a rash below the injection site), NAUSEA (Very nauseous) and FATIGUE (She was expecting the "usual swelling and tiredness" but, "it was more than that, it was worse".) had resolved. At the time of the report, PHARYNGEAL ERYTHEMA (Inflammation in her throat (it was red)) and BACTERIAL INFECTION (Bacteria on the throat) outcome was unknown and MOBILITY DECREASED (Can't walk or move around) had not resolved.        The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) was unknown.   For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter considered MOBILITY DECREASED (Can't walk or move around) to be possibly related. No further causality assessments were provided for PHARYNGEAL ERYTHEMA (Inflammation in her throat (it was red)), BACTERIAL INFECTION (Bacteria on the throat), PRURITUS (Itching below the inject site), VACCINATION SITE ERYTHEMA (Arm was red), VACCINATION SITE SWELLING (Arm was swollen/Expecting the "usual swelling and tiredness" but, "it was more than that, it was worse"), DECREASED APPETITE (Lost her appetite), WEIGHT DECREASED (Weight loss), ILLNESS (Felt very sick/badly), RASH (Developed a rash below the injection site), NAUSEA (Very nauseous) and FATIGUE (She was expecting the "usual swelling and tiredness" but, "it was more than that, it was worse".).
