One eyed says " If you want to extend the meaning of the word abstain to a complete avoidance of any use, then the WT's current blood policy is apostate, since it allows the use of fractions. Not to mention most vaccines, which I'm sure you've taken, are derived from blood in one way or another. To truely abstain from blood in every way, you need to stop vaccinating."
And, I agree- and don't take their view.
