In a 2012 meeting, the FDA voted to allow the use of human fetal cells and adult human tumor cells in vaccines, despite acknowledging the many risks, including that vaccine recipients might later develop cancer.
The first use of human fetal cells in vaccines occurred around 60 years ago, but the practice is increasingly popular. It was always controversial. Immunologists long considered using cells from aborted human fetuses in vaccines to be a high-risk gambit; human DNA debris is much more likely to infiltrate cells in vaccinated individuals than insect or monkey DNA.
Researchers and regulatory agencies have worried for more than 50 years about the potential for injected DNA to cause cancer. According to Dr. Theresa Deisher, a research scientist, primitive (unmethylated) DNA chains from human fetuses have the ability to 1) activate immune receptors that could lead to autoimmune attacks in susceptible individuals who have genetic predispositions that cause their own DNA to be under-methylated, or 2) insert into cells where they could combine with host DNA and cause mutations.
Regulators have in the past predicted that the odds of that happening were less than 1 in a trillion. However, in early gene therapy trials this event did indeed occur in 4 of 9 boys, 1 of whom died from the leukemia the insertions caused.
