The patient was treated with ELECTROLYTES NOS, GLUCOSE (PEDIALYTE [ELECTROLYTES NOS;GLUCOSE]) at an unspecified dose and frequency. At the time of the report, OVERWEIGHT (overweight), ALOPECIA (caller experienced hair loss which continues to this day/Lost hair in clumps), SPINAL STENOSIS (Caller has developed spinal stenosis in Oct 2022), BUNDLE BRANCH BLOCK (a partial bundle branch block in heart) and ARTHRALGIA (joint in body, finger, toe, knee, shoulder, hip, every joint was in excruciating pain/joints in knees are hurting) had not resolved and COVID-19 (had a Covid like flu last December in 2022) outcome was unknown.        For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   Concomitant medication details not reported by the reporter. It was reported that patient had two Moderna shots in 2020. 1st dose in November, second dose in December. Patient said she will never ever take a shot again.

Company Comment: This spontaneous case report concerns a 73-year-old female patient with no relevant medical history, who experienced non serious unexpected events of Spinal stenosis, COVID-19, Overweight, Alopecia, Bundle branch block (AESI) as well as non serious expected event of Arthralgia. Reportedly, 2 weeks after the administration of the second dose of the mRNA-1273 vaccine, the patient experienced hair loss which continues at the time of this report, and, at least half or two thirds of hair was gone. In addition, about two to three weeks later the patient started to have excruciating pain in every single solitary joint in body (finger, toe, knee, shoulder, hip), which lasted about a year in a half. Approximately 10 months after second dose, the patient was diagnosed with spinal stenosis. The patient was treated with epidural steroids shots and physical rehab. Furthermore, the patient developed a partial bundle branch block on an unknown date. In addition, the patient complained that her joints in knees were hurting. Approximately 2 years after second vaccination, the patient had "COVID like flu", as stated. At the time of this report, no further details regarding clinical course of the events were available. The patient's elderly age provides more alternative explanation for the event of Spinal stenosis and having in mind nature of the event (which refers to age-related changes in the spine), the company causality for this event is assessed as not related to the mRNA-1273 vaccine. The patient's elderly age also remains a confounder for the events of Alopecia, Bundle branch block and Arthralgia. No further details were available for medical assessment. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.; Sender's Comments: This spontaneous case report concerns a 73-year-old female patient with no relevant medical history, who experienced non serious unexpected events of Spinal stenosis, COVID-19, Overweight, Alopecia, Bundle branch block (AESI) as well as non serious expected event of Arthralgia.
