"Some people cite the Catholic Church’s objection to certain vaccines, such as the rubella vaccine, that were initially developed in laboratory cell lines that were derived from aborted fetuses. (The vaccines themselves contain no fetal cells.) The church has stated that in those instances members should find alternatives when available but that there is no religious obligation to refuse these vaccines. (Catholic News Service even ends an article on this subject with the wonderful: “Children and unborn children must not pay the price for ‘the licit fight against pharmaceutical companies’ that produce immoral vaccines.”)"
