Some vaccines are developed using aborted fetal cell lines, and some even contain aborted fetal cell line remains. This has been the case since the 1920s, and became widespread in the 1960s, when Leonard Hayflick developed the first widely used aborted fetal cell line from the lungs of a little girl, and used to it grow viruses in her remains for use in vaccines. The Body of Christ simply has not been adequately and accurately informed on this devastating fact.
Pro-life believers have been participating in the abortion industry, most unknowingly. It is time to face that we have been taking part in unfruitful deeds of darkness, to repent, and to come out of sin.
