As Vox's Sarah Kliff points out, "fetal tissue has historically played an important role in scientific research because of fetal cells' ability to rapidly divide and adapt to new environments.

Researchers also used fetal tissue in developing multiple vaccines, including the Rubella and polio vaccines.
