It looks to me, from that link, like some vaccines were produced using cells grown from fetal tissue five decades ago. No new tissue is being used. So there's no soylent green factor here; babies are not being aborted in order to provide ingredients for vaccines. It also appears that the tissues in question were used for cultures to grow live vaccines. When you have a throat swab done to test for strep throat, the swab is placed in a dish of blood products to see if the blood products grow the bacteria they're looking for. The fetal tissue was apparently used the same way as the blood culture. Long story short - the vaccines we get do not contain human biproducts, but they have been tested in human biproducts.
