Well, I guess that means you are ahead of me in the field of rare medical conditions. I stumbled on the condition while researching why my friend would suffer up to three infections after the surgery she had even though she was healthy and the blood she was transfused was clean. I learned that transfusion could cause suppression of immune system due to the actions of the leukocytes from the donor's blood. That was when I saw chimera and realised it was an actual thing.
I appreciate your support and comment. You write pretty interesting posts yourself!
