More trouble ahead for people that have been injected with the experimental Covid 19 biologics.
"Acquired hemophilia A following COVID-19 vaccination, The importance of prompt diagnosis: A case report of cutaneous hematoma occurring 8 days after COVID vaccination."
Cliff notes version:
Abstract
‘Acquired hemophilia A (AHA) is a rare coagulopathy characterized by hemorrhagic manifestations. It has been linked to various conditions, including autoimmune disorders, drugs, tumors, lymphoproliferative disorders, and infections.

We present a case of AHA in a 71-year-old male patient with cutaneous hematoma occurring 8 days after vaccination for COVID-19. This report aims to highlight the risk of FVIII inhibitor development following an immune stimulus, thus improving our knowledge regarding possible vaccination-related adverse events.
Conclusion
The onset of AHA is an often-misunderstood condition with delayed diagnosis, and pathogenetic mechanisms should be more defined. The SARS-CoV-2 pandemic and the extensive vaccination campaign implemented worldwide could be an important trigger mechanism for autoimmune manifestations, especially in predisposed individuals. Coagulation disorders such as AHA can be potentially lethal. Increasing awareness of this rare side-effect following vaccination and its surveillance could help our knowledge of the underlying mechanisms and improve patient outcomes.’
