Well those claims are exaggerated and contain total lies too.

"Before I discuss Deisher’s pseudoscience about vaccines, I think it important to discuss briefly exactly how and when fetal cells are used to make vaccines. First, you need to realize that fear mongering about “fetal parts” in vaccines is, not surprisingly, a distortion of the real situation, which is that the human cell lines are used to make some vaccines. Specifically, the WI-38 cell line is a human diploid fibroblast cell line derived from a three month old fetus aborted therapeutically in 1962 in the US. Another cell line, MRC-5, was derived from lung fibroblasts of a 14 week old fetus in 1966 in the United Kingdom. These are currently the only fetal cell lines used to grow viruses for vaccines"

"Although antiabortion antivaccine activists frequently try to make it sound as though scientists are aborting fetuses left and right just to grind them up to make vaccines (presumably twirling their mustaches and cackling evilly as they slice and dice them), in reality there are only two cell lines used this way"
