Aaron Siri Exposes Shocking Truth About Fetal Cell Lines in MMR Vaccines
In a recent conversation, attorney Aaron Siri broke down why many parents are deeply disturbed by how vaccines like the MMR are produced. He pointed to official CDC ingredient lists showing that cultured cell lines such as MRC-5 and WI-38—originally derived from aborted fetal tissue—are used in the growth process of certain viral vaccines.
Siri explained that viruses cannot replicate on their own; they must be grown in living cells. According to him, the rubella virus used in MMR was cultured using human fetal lung fibroblasts. This claim traces back to historical studies where researchers examined tissue samples from dozens of aborted fetuses to determine which body parts could best sustain viral growth.
Siri referenced his deposition of Dr. Stanley Plotkin—often called the “godfather of vaccines”—and described it as one of the most disturbing records available for public review. The deposition, according to him, detailed studies involving normal, healthy fetuses used for experimental virus culture research.
Many listeners reacted with disbelief and moral outrage, calling the practice a “sacrificial” aspect of modern vaccine production—something they say crosses ethical and religious boundaries.
Siri emphasized that his goal is transparency and informed consent, urging Americans to see the original court deposition for themselves before forming conclusions.
