Ultrasound and Immunological Findings in Patients With Shoulder Injury Related to Vaccine Administration (SIRVA)

Completed

• Conditions: Shoulder Injury Related to Vaccine Administration; Erosion, Localized

• Registration Number: NCT04236193
• Lead Sponsor: University Hospital, Basel, Switzerland

Brief Summary

Accidental vaccine injection into adjunct shoulder structures can cause tissue damage, termed Shoulder injury related to vaccine administration (SIRVA). The immunopathological mechanisms and consequences of SIRVA are unknown.

The study assesses the clinical and immunological consequences of an influenza vaccine if accidentally administered in periarticular space.
