How safe are the Covid vaccines for someone with Factor V Leiden According to the CDC, key considerations that should inform these conversations include likely exposure to the virus that causes COVID-19; risks of COVID-19 to the pregnant patients and their fetus; and current knowledge about available vaccines including efficacy, known side effects, and the lack of available data in this population. In all, 33 percent of patients with factor V activity well above the reference range had either deep vein thrombosis or a pulmonary embolism, compared with only 13 percent of patients with lower levels. These symptoms, as well as the mechanism underlying the formation of these clots, are similar to those from a different type of thrombosis, heparin induced thrombocytopenia (HIT), where specific antibodies bind to a molecule in the blood called heparin, causing platelets to become super sticky and clot. The researchers found that factor V levels were significantly elevated among patients with COVID-19 compared with controls, and they found the association between high factor V activity and COVID-19 was the strongest among all clinical parameters studied. The people you live or spend time with can help protect you and themselves by staying up to date on their COVID-19 vaccines too.

Patients on warfarin should have prothrombin time testing performed within 72 hours prior to injection to determine international normalized ratio (INR); if results are stable and within the therapeutic range, they can be vaccinated intramuscularly. Of note, more people experienced these side effects after the second dose than after the first dose, so it is important for vaccination providers and recipients to expect that there may be some side effects after either dose, but even more so after the second dose.

Van Cott and colleagues also found that the clinical decline toward DIC was foreshadowed by a measurable change in the shape or waveform of a plot charting light absorbance against the time it takes blood to coagulate (waveform of the activated partial thromboplastin time, or aPTT). This was a paused based on 15 reports. It is amazing how we have to be our own doctors, researchers and advocates. The dosing regimen is two doses of 0.5 mL each, one month apart.
