On an unknown date, Red blood cell sedimentation rate: abnormal (abnormal) slowly returned to normal..     For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter did not provide any causality assessments.   The patient experienced symptoms he would put in the category of normal. The patient also took antibiotics as treatment.   This case concerns a 71-year-old male/female patient with a relevant medical history of Ankle Arthritis, who experienced the unexpected non serious event/AESI of Arthritis (ankle arthritis) after mRNA- 1273 Moderna vaccine (Moderna COVID-19 Vaccine / Spikevax). The event occurred approximately 2 month and 5 days after the second dose of mRNA- 1273 vaccine. Treatment with prednisone was prescribed. The rechallenge is not applicable, since the event was reported exclusively after the second dose. Previous history of ankle arthritis remains a confounder. The benefit-risk relationship of mRNA- 1273 vaccine / Moderna COVID-19 Vaccine is not affected by this report   Most recent FOLLOW-UP information incorporated above includes: On 10-Nov-2021: Follow-up received on 10-NOV-2021 included, lab investigation data, vaccination anatomical location, concomitant medications, treatment medications, new events and event outcomes.; Sender's Comments: This spontaneous case concerns a 71-year-old male patient with a relevant medical history of Ankle Arthritis, lymphoma and rasioteraphy, who experienced the unexpected non serious event (AESI) of Arthritis (ankle arthritis) after mRNA- 1273 Moderna vaccine (Moderna COVID-19 Vaccine). The event occurred approximately 1 month and 4 days after the second dose of mRNA- 1273 vaccine. He was also discovered to be anemic but despict that all other lab workup were normal. Treatment with prednisone was prescribed. The rechallenge is not applicable, since the event was reported exclusively after the second dose. Previous history of ankle arthritis remains a confounder. The benefit-risk relationship of mRNA- 1273 vaccine / Moderna COVID-19 Vaccine is not affected by this report.
