There are massive consequences to survivors of the protocol who arguably may have been better off succumbing to the disease, iirc. There’s no point in using a protocol that keeps people alive with no quality of life. (This kind of handoff is discussed in ethics classes in healthcare, the cost/benefit analysis of a treatment on a patient.)
Sources? Anything I've found seems to indicate survivors have gone to have kids and reasonably functional lives - not side effect free, but not by any means worse than death.
