Coronavirus disease 2019 (COVID-19), a highly contagious infectious disease, has had a catastrophic effect on the world's demographics resulting in more than 2.9 million deaths worldwide till January 2021. It can lead to systemic multi-organ complications; in particular, venous and arterial thromboembolism risk is significantly increased. Venous thromboembolism (VTE) occurs in 22.7% of patients with COVID-19 in the ICU and 8% in non-ICU hospitalized patients. Studies evaluating thromboprophylaxis strategies in patients with COVID-19 are needed to improve the prevention of VTE. VTE is the most commonly reported thrombotic complication, with higher incidence rates among critically ill patients. Several vaccines have been licensed and are currently used to combat the COVID-19 pandemic. Also, several cases of vaccine-induced thrombosis have been reported. Vaccination remains the most critical measure to curb the COVID-19 pandemic. There is a broad consensus that the benefits of vaccination greatly outweigh the potential risks of rare vaccine side effects, such as vaccine-induced immune thrombotic thrombocytopenia (VITT). Therefore, the importance of vaccination should be emphasized. This statement aims to focus on VITT.
