Avoiding Shoulder Injury Related to Vaccine Administration: Clinical Prevention Strategies from Australia (cybermedlife.eu)

• Two Australian case reports highlight SIRVA after vaccination
• Most common injuries: bursitis, rotator cuff tears, bone edema
• Prevention: inject into mid-deltoid, never too high

"This clinical article from Australian Family Physician (2016) describes two cases of Shoulder Injury Related to Vaccine Administration (SIRVA) and reviews the literature. SIRVA presents with pain and limited range of motion within hours of vaccination, often due to bursitis, rotator cuff tears, or bone lesions. Correct injection technique—keeping the needle low in the deltoid—is key to prevention. Management includes physiotherapy and corticosteroid injections; surgery may be needed for severe cases."
