Some more non-settled science, courtesy of The Ottawa Hospital:
A large Canadian study has shown a link between blood donor characteristics and transfusion recipients' outcomes. This is the first study to suggest that red blood cell transfusions from young donors and from female donors may be associated with poorer survival in recipients.
Guess the old simple classification system of sorting all blood into a couple of types was too simple. Just because blood doesn't cause an instant life threatening reaction doesn't mean it is totally compatible.
And like any good science article, the conclusion is "more research is needed!"

The dataset looks big enough that most of those flukes should have averaged out of the final results. Something weird seems to be going on, something unexpected. Those sort of results are where the interesting new science tends to come from so this is a case where the "more research needed" is apt.
