The coronavirus disease 2019 (COVID-19) pandemic has led to millions of confirmed cases of COVID-19 worldwide and billions of vaccines against SARS-CoV-2 have been administered (TTS is a rare symptom characterized by acute venous or arterial thrombosis, thrombocytopenia, and positive PF4-heparin ELISA. The peak time for symptoms onset is 6 to 14 days after vaccination and the symptoms can range from mild adverse effects to death (Inactivated COVID-19 vaccines have been widely used for vaccination around the world, but there have been few studies on TTS-related safety after vaccination. Therefore, there is an urgent need to study whether inactivated COVID-19 vaccines could affect coagulation function. Here, we report the results of a phase IV clinical trial to evaluate the effects of an inactivated vaccine (CoronaVac) on coagulation function, immunogenicity, and other adverse reactions. Fasting glucose was also detected and evaluated.
