Does fetal DNA in vaccines change our genetics?

In a video, a Peter McCullough colleague claims that vaccines are made using cells from old abortions, that they have pieces of fetal DNA in them, and that this DNA can integrate and combine with a person’s own cells.

A number of scientists have found the conclusions about the paper referenced by McCullough, written by Theresa Deisher, which self-references her own work, to be “unsupported and implausible.” As pointed out by Teja Celhar, “the whole hypothesis of the author (which is misleadingly presented as fact) is based on the author’s own measurements of fetal cell-derived DNA, which has serious methodological problems that could be easily prevented by RNase treatment. Additionally, the measurements should have been validated by a different method (e.g. qPCR, capillary gel electrophoresis) and ideally by an independent researcher/institution.”

Viruses are obligate intracellular parasites that need host cells to grow. Since human cells are sometimes best for growing human viruses, some vaccines use cell lines derived from two elective pregnancy terminations back in the 60s. Because these cell lines are practically immortal, manufacturers can continue using this cell line; there are no new sources of human fetal cells.

Dr. Stanley Plotkin, in a series of videos, explains how we can use fetal cell lines developed decades ago to manufacture vaccines today. The cell lines provided multiple advantages, including absence of animal viruses, a fertile place for cell growth, and the immortality of the cells (meaning no new fetuses need be destroyed to make another cell line).
