Other sites seem to be running loose with the facts implying that a constant supply of new fetuses is required to keep the supply for those two vaccines going.
With the number of abortions performed in the world being as large as it is, I don't think that any company will ever have to encourage or pay a particular woman to have an abortion in order to obtain a particular tissue sample.
The primary moral issue will be that these researchers only have access to these particular types of tissue samples because of the ongoing moral atrocity of abortion.
It has been reported on numerous occasions that adult stem cells have been more successful in treating medical conditions than fetal stem cells. I'm hoping that a suitable substitute for fetal diploid tissue samples can be harvested from consenting adults, but I don't know enough of the science to know if what I am asking is possible or even makes sense to ask.
I don’t like to paint with too broad a brush, but the anti-vax activists can be so devoted to their cause that they are not always above, ahem, stretching the truth a bit.
Many are also johnny-come-latelies to the pro-life cause, which further raises my alert level. My bottom line is that I’d like to see alternative germ lines developed, but frankly, we have much bigger fish to fry, and getting too cozy with the anti-vax crowd does not hasten the day that the abortion machine is brought to a stop.
