Recently, I discovered that some common vaccines were developed through the use of tissue harvested from electively aborted babies. The babies were not aborted for the purpose of harvesting the tissue but for the convenience of the mother at the time. The scientists harvested the tissue after the fact. Basically, some lung cells were harvested (about 30 years ago) from the fetus and these cells continue to be multiplied and used even today as a culture through which weak viruses are produced and then are extracted and used as vaccines. Here is an article about it on National Right to Life. http://www.rtl.org/prolife_issues/LifeNotes/VaccinesAbortion_FetalTissue.html I was surprised first of all that I had not heard of this practice before. Many of these vaccines I and my children have already received over the years. So the question, is it lawful to use such medical technology despite the sinful origins in which the culture was obtained? OR should we refrain from those particular vaccines? Do you know of any Reformed authors who have written about this ethical question? (Please provide references if you do) ** Disclaimer: If you already reject any vaccine use at all, then please do not respond to this thread. I already know what your answer will be. This is a discussion for those who accept the practice of vaccination in general. Thank you!
