anthrax is unnecessary, the swine blood is sufficiently out of type from human blood there will be a major (fatal) reaction to it

Nope. Pigs aren't different enough.

Xenotransfusion

XTF has not been tested in humans, however current evidence shows that pRBCs will function normally in humans due to a relation between porcine blood groups and human ABO group system.[6] In addition, it is possible to produce pigs with type O blood and it is also possible to genetically modify the pig to make its blood more compatible with humans. Sus scrofa domesticus’s blood will be used to save lives and to increase blood quantity. The organism will be kept alive and no serious harm will be involved in XTF. It will be similar to how blood is removed from humans. Only 10% of the animal’s blood volume will be used each time, therefore, it is ethically acceptable to raise pigs for periodical blood collection as it does not damage the health of the animal. It will also be ethical to use pRBCs on humans since it will not cause a severe harm on human’s health.
