Is using medication derived from tissue of aborted fetuses compatible with Catholic teaching?

**Obviously no one should take any medical advice from StackExchange, but from a purely theological/canon-law perspective:** What does Catholic teaching or canon law say about using medicine developed from cells taken from an aborted fetus? Is using such medication compatible with the teachings on human dignity and the origin of life? Question inspired by a recent *Guardian* article on the drug Regeneron, headlined 'Covid drug given to Trump developed using cells derived from aborted fetus' : > The stem cells used to develop the drug are known as HEK-293T cells, a line of cells used in laboratories. The cells were originally derived from an embryonic kidney after an elective abortion performed in the Netherlands in the 1970s.
