Anders, I have been working on that topic for a long time. Bulky material.
Here is a little tidbit to start:
The 1981 article by Dixon/Smalley makes this statement:
Also, if a recently developed fluorinated blood substitute (Fluosol-DA) proves to be safe and effective, its use will not conflict with Witness beliefs.
Fluosol-DA had already been tested on Jehovah's Witnesses at this point (1979). That project - the testing of Fluosol-DA on human subjects - had been spearheaded by Ron Lapin and his JW cohorts. The Watchtower had already arranged the trials using JW subjects at the time this article was written. That is why the statement that "...if...Fluosol-DA proves to be safe and effective" is a really misleading statement - it already was being used on JWs. The Fluosol-DA would later be pulled off the market by the FDA.
