Sasaki et al. presented an intriguing underlying pathomechanism in which the vaccine could cause aberrant immunity and DKA. 2 However, there is a lengthy time between vaccination and the onset of diabetes. We should be aware of the likelihood of a medical issue co-occurring with the COVID-19 vaccine that can lead to type 1 diabetes in a COVID-19 vaccine recipient. A vaccination recipient, for example, could develop dengue, 3 and dengue could be a cause of DKA. 4 Finally, we agree with the conclusions of Sasaki et al. 2 on the importance of a thorough assessment of the problem and the recognition of probable vaccination-induced diabetes. On the other hand, we would like to add a note about another possible concurrent issue that could cause DKA in a vaccine recipient.
