Chronic Inflammatory Demyelinating Polyneuropathy Post-mRNA-1273 Vaccination. Cureus. 2022;14(4):e24528. Published 2022 Apr 27. doi:10.7759/cureus.24528https://hdl.handle.net/1805/33919Massive efforts are being made to develop coronavirus disease 2019 (COVID-19) vaccines at an unprecedented rate. The vaccinations' adverse impact profile, on the other hand, has not been well established. Neurological complications are increasingly reported as a result of these vaccines. One such complication identified is immune-mediated inflammatory polyneuropathy, which affects peripheral nerves and neurons. We report a case of chronic inflammatory demyelinating polyneuropathy (CIDP) post-mRNA-1273 (Moderna) COVID-19 vaccine. Recognizing this complication and distinguishing it from Guillain-Barré syndrome enables timely initiation of treatment. Additionally, our report highlights a possible link between vaccination and subsequent development of CIDP, but conclusive evidence of a causal relationship requires more extensive studies.en-USAttribution 4.0 InternationalCovid 19Vaccine complicationCovid-19 vaccineDemyelinating disorderDemyelinating polyneuropathyModerna mRNA-1273 vaccineChronic inflammatory demyelinating polyneuropathyArticle
