To the Editor:We would like to share ideas on the publication “Shoulder Injury Related to Vaccine Administration: Diagnosis and Management.” Wood and Ilyas mentioned that “Large-scale studies are necessary to better understand the pathophysiology of SIRVA, its treatment, and its outcomes. Overall, the initial priority in managing SIRVA should be awareness and prevention.” We agree that coronavirus disease 2019 vaccine, if administered by an inexperienced practitioner, can result in shoulder injury. During the pandemic, mass vaccination is required and the safety of vaccination procedures may be forgotten. We should restate the importance of a standard vaccine injection procedure and should consider tools such as ultrasound-guided injections for difficult cases. Finally, one should note that not all shoulder injuries after vaccination are the result of a poor vaccine injection technique. It is necessary to rule out any other cause of injury that a vaccine recipient might have experienced.
