The occurrence of additional non-serious events is detailed below.     It was reported that patient did not receive any other vaccines in the 4 weeks prior to COVID-19 vaccine and information on previous COVID-19 vaccination doses were unknown. No parental vaccine exposure was reported.  Concurrent medical conditions included Adrenal insufficiency (diagnosed when patient was 18 years old).   In January 2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. In February 2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On 15-Feb-2021, the patient experienced ADRENAL INSUFFICIENCY (adrenal insufficiency crashed/she started to feel unwell./blood pressure/ got violently sick/ throwing up/couldn't keep anything down/ nausea) (seriousness criterion medically significant) and PYREXIA (Her fever spiked to 104F). On an unknown date, the patient experienced VACCINATION SITE PAIN (1st dose in JAN2021 and stated that her arm hurt and the sore arm only lasted for a few hours). The patient was treated with PARACETAMOL (TYLENOL) for Fever, at an unspecified dose and frequency. On 15-Feb-2021, ADRENAL INSUFFICIENCY (adrenal insufficiency crashed/she started to feel unwell./blood pressure/ got violently sick/ throwing up/couldn't keep anything down/ nausea) and PYREXIA (Her fever spiked to 104F) had resolved. At the time of the report, VACCINATION SITE PAIN (1st dose in JAN2021 and stated that her arm hurt and the sore arm only lasted for a few hours) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Blood pressure measurement: Blood pressure decreased. On an unknown date, Body temperature: fever spiked to 104F.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   Concomitant drugs were not reported. It was reported that with dose 1 patient had arm hurt and the sore arm only lasted for a few hours.
