COVID-19 Vaccine AstraZeneca is an adenovirus vector vaccine which received a conditional marketing authorisation in the EU on 29 January 2021 for active immunisation against COVID-19 in individuals 18 years of age and older. A molecule called activated protein C (APC) prevents blood clots from growing too large by inactivating factor V. In people with the factor V Leiden mutation, APC is unable to inactivate factor V normally. Factor V Leiden is the name of a specific gene mutation that results in thrombophilia, which is an increased tendency to form abnormal blood clots that can block blood vessels. The Johnson & Johnson COVID-19 vaccine was linked to an increased frequency of blood clotting, so I would not. 7, 8 Symptoms are often severe and persistent including severe headache, visual changes, altered mental status, nausea, vomiting, abdominal pain, shortness of breath, bleeding or petechial, and leg pain or swelling. What Is Factor V Leiden? Factor V Leiden, is a genetic variant leading to alteration of the inactivation site of factor V, which in turn leads to activated protein C resistance and a prothrombotic state.

Thrombosis Canada has reviewed recent reports from the United Kingdom and Europe relating to the SARS-CoV-2 (COVID-19) vaccine made by AstraZeneca and the development of a very rare type of thrombosis (blood clots) that is associated with thrombocytopenia (low blood platelets). Factor V Leiden (rs6025 or F5 p.R506Q) is a variant (mutated form) of human factor V (one of several substances that helps blood clot), which causes an increase in blood clotting (hypercoagulability).Due to this mutation, protein C, an anticoagulant protein that normally inhibits the pro-clotting activity of factor V, is not able to bind normally to factor V, leading to a hypercoagulable state . MMR (j),(k) (Severe allergic reaction (e.g., anaphylaxis) after a previous dose or to a vaccine component Pregnancy. Factor V is a coagulation protein in the blood. New research points to disturbances in blood clotting protein factor V activity as both a potential cause of blood clotting disorders with COVID-19, and to potential methods for identifying at . Known severe immunodeficiency (e.g., from hematologic and solid tumors, receipt of chemotherapy, congenital immunodeficiency, long-term immunosuppressive therapy (c) or patients with HIV infection who are severely immunocompromised).
