Relationship Between Vaccination and Immune Thrombotic Thrombocytopenia: Coincidental or Causal?

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a complication developed in patients due to vaccination. High-risk factors like a prothrombotic state predispose such a condition. Due to the increase in vaccinations after the coronavirus 2019 (COVID-19) pandemic, the predisposition to risk factors has increased. Hence, complications occur at a very young age. This case report is of a young male who developed venous sinus thrombosis post the COVID-19 vaccination and was diagnosed and treated promptly.
