Shoulder injury related to vaccine administration (SIRVA) following mRNA COVID-19 vaccination: Report of 2 cases of subacromial-subdeltoid bursitis

Abstract

Shoulder pain has been reported as a common side-effect after COVID-19 vaccination particularly after administration of mRNA vaccines. Although it is usually mild and self-limiting, occasionally it can become more extensive causing severe pain and marked limited range of motion. Shoulder injury related to vaccine administration has been reported following injection of other routine vaccines. In this case report, we describe 2 cases of shoulder injury related to vaccine administration due to subacromial-subdeltoid bursitis after administration of mRNA COVID-19 vaccines.
