Found this Sharyl Attkisson video cross-posted at Unconditional Jessica (Dr. Jessica Rose)
The doctor in this video (Dr. Jordan Vaughn, if I heard correctly) is having good results treating people with problems from COVID and COVID vaccines that are due to microclots -- which cause a wide range of symptoms. I don't know what else he's doing for them, but triple-anticoagulant therapy is mentioned, although without detail on which anticoagulants are being used. Patient descriptions of the results are extremely positive. A direct link to this Attkisson story on YouTube is https://www.youtube.com/watch?v=Glq7era7BqM.
I agree with you completely. Nattokinase might actually BE one of the anticoagulants Dr. Vaughn is using; it's been widely recommended including by Dr. McCullough and I can't imagine anyone researching the issue of clotting from the Spike protein NOT being aware of Nattokinase at this point.
All the supplements and drugs you mention have good support in the scientific literature and elsewhere, including patient reports. I'm a big believer in multiple remedies for anything serious and, especially if one is older or already has issues, for prevention.
