Septic Arthritis of the Shoulder After SARS-CoV-2 Pfizer Vaccination: A Case Report.

CASE: We report a case of a 68-year-old woman who developed left shoulder glenohumeral joint septic arthritis within 1 week of receiving the COVID-19 Pfizer-BioNTech vaccine.

CONCLUSION

Common vaccine complications include injection site pain, fever, chills, arthralgia, and hypersensitivity reactions. A less common and more serious complication of septic arthritis has been reported and requires invasive treatment of surgical irrigation and debridement, and culture-specific parenteral antibiotic therapy. The current report highlights the clinical presentation and significant potential for serious complication with the improper technique. We urge vaccine administrators to practice caution and aseptic technique when vaccinating patients to reduce the risk of complication and morbidity.
