Vaccine-inducted thrombotic thrombocytopenia (VITT) has also been referred to as vaccine-induced prothrombotic immune thrombocytopenia (VIPIT) or thrombosis with thrombocytopenia syndrome (TTS). This condition is similar to heparin-induced thrombocytopenia (HIT) but is associated with prior administration of the Johnson & Johnson/Janssen or AstraZeneca COVID-19 vaccines without prior exposure to heparin. To date (June 8, 2021), this condition has not been reported in patients who have received the Moderna or Pfizer COVID-19 vaccines.
A national multicentre retrospective study conducted in China revealed that the incidence of thrombocytopenia (< 150 * 109/L) on admission in COVID-19 was 36.2% [3], which is similar to that in SARS (4045%%) and MERS (36%) [4]. It has been widely accepted that thrombocytopenia is indicative of disease severity, and a progressive decline of platelet counts was significantly associated with increased mortality.
