I think something that would totally "close the gap" with JW's and not accepting blood but accepting it through the fractions of fractions would be to harvest white blood cells from mother's milk (there are already mother's milk banks) and then transfuse them to Witness patients who need WBC's. Since technically they are not from blood, I think it would be an interesting loophole.
Anyone here know about a disease that can only be cured/treated with WBC's? How about platelets? It would be the last and only thing that JW's cannot accept...
