COVID-19 vector-based vaccine causing thrombosis.

The number of people affected by COVID-19 is staggering and countries are rushing and competing to vaccinate their populations. However, there has been a concern about the association between COVID-19 vector-based vaccines and thrombosis. The proposed mechanism by which a COVID-19 vector-based vaccine can cause thrombosis is called vaccine-induced immune thrombotic thrombocytopenia (VITT). This commentary will provide an easy sketch of VITT as well as presentation of thrombosis after COVID-19 vaccines and proposed treatment.Communicated by Ramaswamy H. Sarma.
