Companies like 23andMe now offer direct-to-consumer DNA genetic testing kits that include testing for Factor V All rights reserved. The Johnson & Johnson COVID-19 vaccine was linked to an increased frequency of blood clotting, so I would not recommend that vaccine. In some people who have had the first dose of the AstraZeneca vaccine, unwanted clotting is being reported in the brain, known as cerebral venous sinus thromboembolism (CVST).

Executive Master of Public Administration Pfizer-BioNTech Death rates were significantly higher for patients with lower levels of factor V, with evidence suggesting that this was due to a clinical decline toward a DIC-like state. It should be noted that, immune tolerance therapy, treatment for hepatitis C, and HIV and other conditions including the use of immunosuppressive agents do not preclude a person from receiving the available vaccines. People who have the factor V Leiden mutation are at somewhat higher than average risk for a type of clot that forms in large Disable anytime.

The mechanism behind this is also unclear, but the COVID-19 infection likely causes these clots either by destroying the bone marrow and preventing platelets from being made, by causing the immune system to destroy platelets, or by increasing the use of platelets to repair damage to lungs and other tissues as a result of the infection (or a combination of all these things). In March 2020, in the early days of the COVID-19 pandemic in Massachusetts, Van Cott and colleagues found that a blood sample from a patient with severe COVID-19 on a ventilator contained factor V levels high above the normal reference range. Engage in a serious and supportive conversation where you can address fears and map out the potential benefits or side effects of receiving a vaccine.
