We read the report by Kitajima et al 1 with great interest. They demonstrated 4 cases of antimelanoma differentiation-associated gene 5 (anti-MDA5)-positive interstitial lung disease (ILD) manifested following SARS-CoV-2 vaccination and suggested the possibility of the increased incidence of anti-MDA5- associated ILD (anti-MDA5-ILD) due to the vaccination. This study interested us since we also encountered a case of new-onset anti-MDA5 antibody-positive clinically amyopathic dermatomyositis (CADM) with ILD, developed 8 weeks after BNT162b2 vaccination during the SARS-CoV-2 vaccination campaign in Japan.
