For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   Patient stated that she had a significant spike in the neuralgia severe enough to warrant a call to the primary care physician where she prescribed a course of steroids which unfortunately did not help.
