What vaccines contain cells of aborted fetuses?

Question

Update:

WI-38 (ingredient in MMR vaccine) is a diploid human cell line composed of fibroblasts derived from lung tissue of a 3-month-gestation female fetus.

Answer 1

Short answer - none!  WI-38 isn't an ingredient of MMR or any other vaccine. There's some useful information at the link, and the Wikipedia article you misquoted provides more detail of WI-38's role in vaccine production.
