How do you view the use of tissues of the dead from funeral homes (even if permitted by the family, as obviously it isn't now)? (Clearly different, interested).
What gave them the idea to use the diff.cells from the lungs of the miscarried fetus... what's the history?
Tissues from the dead are used all the time in transplants and grafts, but I believe you may be hinting at the sale of tissues from dead folks that is stolen from corpses and represented as being otherwise healthy tissue, obviously we are both against that.
As far as the use of fetal lung tissue as one of the passages through which a live virus is passed in the manufacture of vaccine and who thought of that, you'll have to ask someone who is a better lab rat than I.
Listen to the caller about miscarried embryonic cells. oops, well we can imagine his points.
