The Vatican says that it's "morally acceptable" to receive a vaccination for the coronavirus, even if the vaccine's research or production involved using cell lines derived from aborted fetuses, given the "grave danger" of the pandemic. The Congregation for the Doctrine of the Faith, the Vatican office charged with promoting and defending church morals and traditions, said in a document released Monday that "when ethically irreproachable Covid-19 vaccines are not available ... it is morally acceptable to receive Covid-19 vaccines that have used cell lines from aborted fetuses in their research and production process."
