Dr. Richard Fleming: Pfizer Vaccine Causes Blood Clots Under Microscope Add the Pfizer vaccine and the red blood cells lose their oxygen carrying capacity and the red blood cells start to clot... This is exactly what we are seeing with the VAERS reporting. This is exactly what we are seeing with neurologic harm, with cardiac harm, with blood clots occurring in the body. This is proof positive that these vaccines cause this type of damage under the microscope just by simply being added to the blood of a human being... I think it is time the FDA and CDC do their job instead of giving it lip-service."
