1. Vaccines manufactured in human fetal cell lines contain unacceptably high levels of fetal DNA fragment contaminants. The human genome naturally contains regions that are susceptible to double strand break formation and DNA insertional mutagenesis. The "Wakefield Scare" created a natural experiment that may demonstrate a causal relationship between fetal cell-line manufactured vaccines and ASD prevalence. https://www.ncbi.nlm.nih.gov/pubmed/26103708

3. Vaccines that use aborted fetal cells are listed below.
WI-38, developed in 1961, is composed of fibroblasts derived from lung tissue of a three month old white female fetus.
MRC-5, developed in 1965, is derived from the lung tissue of a 14-week-old male (Britain).
RA-273, developed in 1964, is cultivated on WI-38. The rubella virus strain RA 27/3 was obtained from an infected aborted fetus.
IMR-90 is considered an alternate for WI-38 and other standard human lung cell strains. Human diploid fibroblast strain IMR-90 was derived by W.W. Nichols and associates from the lungs of a 16-week female fetus. (This can be used to substitute WI-38).
