Title: Clots and low platelet count - is there a connection with disease?
Post by: set fair on 18/03/2021 13:33:36
Professor Roger Seheult, MD. (of Medcram) reported individual patients who had bleeding in some parts of the body and clots in other parts. The timing of this in vaccinees may suggest spike debris after it has been attacked by the immune system.

How big do you think this "debris" is?

Another theory now being investigated is that the vaccine may be affecting people with low platelet count due to antibodies against platelets.
- Platelets cause clotting
- Normally, low platelets cause bleeding
- But platelets with antibodies attached are more sticky, and may cause clotting
- We know that SARS-COV2 infection can cause problems with clotting in some people - could this be related?

Low platelets can actually be a symptom of "clot" formation: because blood thrombus presents a sticky surface to which platelets can adhere, if you end up with a big intravascular thrombus, you have a sink capable of sucking in your platelets and depleting the count in circulation.

The EMA doesn't seem to think so.

I was thinking these fragments may mimic or block the bodies protein messengers.
