Dear Editor, we would like to share ideas on the publication “Severe immune thrombocytopenia following COVID-19 vaccination (Moderna) and immune checkpoint inhibitor: A case report [1].” Cong et al. noted that “To the best of our knowledge, this is the first case of ITP following Moderna inoculation among Asians … cancer patients receiving immune checkpoint inhibitors [1].” This isn't the first time Asians have been involved in a situation like this. Su et al. [2] previously described a case of ITP following COVID-19 Moderna immunization. In addition, the presence of ITP in a vaccine recipient may or may not be linked to the COVID-19 vaccine. It is necessary to rule out the possibility of a background disorder or a concurrent medical problem. In the problematic instance, there is frequently no information about the patient's health or immune status prior to vaccination.
Declaration of Competing Interest
None.
