Post-Influenza Vaccine Subdeltoid bursitis

Area of Science:

• Orthopedics
• Immunology
• Public Health

Background:

• Subdeltoid bursitis is an inflammation of the bursa located in the shoulder.
• Vaccine administration, particularly intramuscular injections, carries a risk of local complications.
• Influenza vaccination is a critical public health measure for preventing seasonal illness.

Observation:

• A 61-year-old female experienced persistent shoulder pain three months post-influenza vaccination.
• Magnetic Resonance Imaging (MRI) confirmed subdeltoid bursitis as the diagnosis.
• Symptoms began immediately following the injection and persisted for months.

Findings:

• The patient's subdeltoid bursitis was directly linked to the influenza vaccination injection.
• Improper vaccine administration technique is identified as the primary cause of injection-related bursitis.
• The condition, though painful, is preventable through correct procedures.

Implications:

• Improved training for healthcare professionals on proper vaccine injection techniques is crucial.
• Implementing standardized protocols for vaccine administration can reduce the incidence of iatrogenic subdeltoid bursitis.
• Early diagnosis and conservative management, including medication and physical therapy, can lead to favorable patient outcomes and return to function.
