Vaccines Developed With Aborted Fetal Cell Lines Exposed

Human fetal cell lines are used to culture some vaccines. They are listed on the CDCs Vaccine Excipient list as WI-38, MRC-5, HEK293, PERC.6.

WI-38 is a diploid human cell culture line composed of fibroblasts derived from lung tissue of an aborted female fetus.

MRC-5 (Medical Research Council cell strain 5) is a diploid human cell culture line composed of fibroblasts derived from lung tissue of a 14-week-old aborted male fetus.

Human embryonic kidney cells 293, also often referred to as HEK 293, HEK-293, 293 cells, or less precisely as HEK cells, are a specific cell line originally derived from human embryonic kidney cells grown in a tissue culture.
