During 2020 and 2021, the global pandemic of coronavirus disease 2019 (COVID-19) due to severe acute respi- ratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in high death rates and acute and chronic morbidity in all countries. The rapid development of new mRNA vaccines to SARS-CoV-2 brings hope that the spread of this virus can be controlled. ⋯ Studies have begun to in- vestigate whether antibodies to the SARS-CoV-2 spike cross-react with platelet factor 4 (PF4/CXLC4) and mim- ic autoimmune heparin-induced thrombocytopenia. This Medical Science Monitor Editorial aims to briefly update the current status of studies on a possible rare complication of using new mRNA vaccines to prevent COVID-19.

BACKGROUND Since the outbreak of COVID-19 in December 2019, there have been 96 623 laboratory-confirmed cases and 4784 deaths by December 29 in China. We aimed to analyze the risk factors and the incidence of thrombosis from patients with confirmed COVID-19 pneumonia. MATERIAL AND METHODS Eighty-eight inpatients with confirmed COVID-19 pneumonia were reported (31 critical cases, 33 severe cases, and 24 common cases). ⋯ Univariable logistic regression analysis showed that the occurrence of DVT was positively correlated with disease severity (crude odds ratio: 3.643, 95% CI: 1.218-10.896, P<0.05). CONCLUSIONS Our report illustrates that critically or severely ill patients have an associated high D-dimer value and high Padua score, and illustrates that a low threshold to screen for DVT may help improve detection of thromboembolism in these groups of patients, especially in asymptomatic patients. Our results suggest that early administration of prophylactic anticoagulant would benefit the prognosis of critical patients with COVID-19 pneumonia and would likely reduce thromboembolic rates.
