On 29 Dec 2020, the patient received their first of two planned doses of mRNA-1273 (Lot # 039K20A) intramuscularly in the left arm for prophylaxis of COVID-19 infection.   On 29 Dec 2020, the patient reported that the vaccine was administered in her left shoulder but that it seemed kind of high.  The patient mentioned to the nurse giving her the vaccine that it felt strange going in and that it did not feel like a normal injection.

She also stated that her left shoulder was much lower than the right.  On that same day, she went to an orthopedic urgent care where she was told that the vaccine had potentially nicked a nerve causing the issues in her arm.  However, without an MRI, the urgent care was unable to provide a definitive diagnosis. The patient was prescribed steroids and was told that she could not be referred for an MRI until the nerve became less agitated and inflamed once the steroids took effect, in approximately one week. Treatment for the event included oral steroids.  Action taken with mRNA-1273 in response to the events was not provided.   The outcome of the events, vaccine was administered in should and seemed kind of high, shot felt strange going in, can't move or lift arm at all, nicked nerve, left shoulder much lower than the right, and level of pain was 10 out of 10 a few hours later, was not reported.; Reporter's Comments: This case concerns a 40-year-old female patient who experienced the events of vaccine was administered in should and seemed kind of high, shot felt strange going in, can't move or lift arm at all, nicked nerve, left shoulder much lower than the right, and level of pain was 10 out of 10 a few hours later.

Based on the limited available information, a definitive assessment with regards to a drug: event-causal association cannot be provided at this time. However, due to the temporal association between the onset of the event and the administration of the drug, a causal relationship cannot be excluded. Hence, the events of shot felt strange going in, can't move or lift arm at all, nicked nerve, left shoulder much lower than the right, and level of pain was 10 out of 10 a few hours later are assessed as possibly related to mRNA-1273. The event of vaccine was administered in should and seemed kind of high is a procedural issue and assessed as not applicable.
