Dear Father: What is the Church’s position on using drugs and vaccines derived from voluntary aborted fetus?
Dear friend in Christ,
If a vaccine is available that was not derived from abortion, the Catholic must choose that. If one is not available, the Church essentially leaves it up to the individual’s conscience.
(A quick note about conscience: following my conscience does not mean “doing what I want to do”; it means carefully considering and praying about an issue before making an informed moral decision.)
