Serious side effects of vaccinations are not common, though rare complications can occur. We present a case of one such uncommon side effect, influenza vaccine-related subacromial/subdeltoid bursitis. ⋯ Vaccine-related shoulder dysfunction includes a range of pathology, from osteonecrosis to bursitis, which will be reviewed in this report. Recognition of infrequent vaccine-related musculoskeletal pathology is important to prevent delay of diagnosis.
