I'm Catholic and was wondering the same thing. I asked our priest, but he wasn't much help, so I asked another lady who does all homebirth, doesn't vaccinate for multiple reasons (didn't know this til after I asked her) home schools, and teaches NFP, and is generally the authority in our parish on the "true" teachings of the Church-I say that because there are so many misconceptions about what the Church teaches
; and most are totally stupid, but I digress.
Anyhow, she said, that per her research, (and she's obsessive about it-not unlike myself), the vaccines that were propagated on fetal tissue weren't prohibited, because the baby had already been killed, and would have been, whether the vaccine would have been made from it or not, but she was uncertain as to whether she wanted to support that kind of industry at all. Therefore, that, along with the questionable benefits, pushed her to the non vax side.
She quoted a bunch of writings and such, but I didn't write it down and it was after Mass, so can't repeat them for you. And, what she said makes sense. The baby would have been aborted anyway, but why, when there are so many questions about the value of vax anyway, would a person want to encourage *that* industry? I was on the fence, but learning they made vax from aborted babies grossed me out-to the point I was very nearly sick to my stomach.
(BTW-I'm not interested in debate. Abortion is wrong. Period. You're entitled to your opinion, but we both must use the same facts.
) Ok Im off the soapbox now.)
I hope someone is able to come up with the actual writings on it-there was an article in the diocesan paper a while back, also-before I was pg so didn't pay much attn to it, darn it.
