Pranav Ish and Shekhar Kunal for their critical reading of our article 1, 2 . As they indicated, it is important that myocarditis be ruled out in this case. Although we did not mention this issue in our brief report, we did indeed rule out the possibility of myocarditis in our diagnosis. Electrocardiography and echocardiography revealed no significant abnormalities. In addition, serum creatine kinase levels during hospitalization were below the upper limit of the normal range. Having ruled out myocarditis, we diagnosed the patient as having interstitial lung disease (ILD) caused by COVID-19 vaccination. Around the time of our case report, two additional cases were reported in Asia 3, 4 . To our knowledge, all 4 of these cases were Asians 1, 3, 4, 5 . In addition, Park et al. also report that 8 out of 10 cases of influenza vaccine-related ILD were Asians 5 . This suggests that interstitial lung disease after COVID-19 vaccination may be more common in Asians. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 vaccine-related adverse events including myocarditis is essential for appropriate therapy. In addition, we think that COVID-19 vaccine-related ILD may also be ignored and underdiagnosed, especially in Asia, and therefore should also be considered in diagnosis. In conclusion, careful attention should be paid to COVID-19 vaccine-related ILD, particularly in Asian countries. Further research is needed to examine the relation between COVID-19 vaccine-related ILD and race . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 A case of severe interstitial lung disease after COVID-19 vaccination Multisystem Inflammatory syndrome following COVID-19 vaccination-ignored and underdiagnosed COVID-19 mRNA Vaccine-induced Pneumonitis: A Case Report Manuscripts submitted to QJM
