Unilateral Erosive Arthritis Following Moderna COVID-19 Vaccination

A novel coronavirus was identified at the end of 2019, causing a pneumonia epidemic in China, which later rapidly spread to cause a global pandemic. However, most people who contracted the COVID-19 had mild to moderate symptoms. A fair percentage developed ARDS, Septic shock, and multi-organ failure. Given the necessity of immunization in combating this disease, COVID-19 vaccines were widely deployed, giving rise to multiple reported cases of post-vaccination autoimmune flareups and new onset of autoimmune phenomena. We present a case of an 81-year-old female who was diagnosed with erosive arthritis post COVID-19 vaccination.
