Persistent shoulder pain and dysfunction after vaccination are relatively rare but well-known complications after inoculations into the deltoid muscle. The term SIRVA (shoulder injury related to vaccine administration) is frequently used to encompass many of these occurrences; however, multiple distinct pathologies with similar presentations have been reported after vaccination. We performed a systematic review of the literature on vaccine-related shoulder injuries to help guide practitioners in appropriate workup and treatment based on specific diagnoses.
