Christians are simply to make an adequate effort to abstain from blood (Acts 15:19-21).
I've explained at length to you why these types of statements are based on an ungrammatical concept.
As a general rule, with the exception of Heptavax-B, active immunizations are not produced from blood.
Most childhood vaccinations involve blood at some point in their production. Examples would include MMR II, MUMPSVAX, ATTENUVAX and MURAVAX II by Merck & Co. The growth mediums for these vaccines (e.g. Medium 199, MEM, etc) typically contain both human albumin and fetal bovine serum. Additionally the vaccines themselves contain human albumin as an adjuvant or excipient. Other examples of this include VARIVAX and VAQTA, also by Merck & Co., EOLARIX, INFANRIX, and GLAXO by SmithKline Beecham, PENTACEL by Aventis Pasteur, and Connaught Laboratories IPV just to name a few. The acceptance of some of these vaccines is virtually unavoidable in modern society.
On the subject of blood components in comparison with fractions: plasma for example is a major component unique to only blood as created by God.
You're co-opting blood banking terminology which is simply reflective of the way blood is packaged and sold to medical and laboratory facilities and nothing else. Most college level textbooks do not list plasma as a component. Plasma is the colloid created when the albumin protein is suspended in water. Albumin solutions are osmotically equivalent to normal plasma. The difference between an albumin solution and normal plasma is the presence of additional proteins that Witnesses consider to be 'matters of conscience.'
Hemoglobin is a protein also found in the tissues of some invertebrates.
Human hemoglobin is unique to human blood.
The reason the faithful and discreet slave left the acceptance or refusal of these blood products an individual choice is because or these types of people.
LOL Blood is ubiquitous in modern medicine. Everyone in developed countries has accepted a blood fraction at some point in their lives.
