Please see below from the United States Conference of Catholic Bishops, an explanation of moral justification in receiving current COVID-19 vaccines. A thorough investigation into the development of forthcoming COVID-19 vaccines finds a remote connection to an abortion that took place decades ago. While we are all called to do what we can to aid in the development of a COVID-19 vaccine that has no connection to abortion, the Bishops of the United States find it morally justifiable to receive the vaccines currently in production until a viable alternative vaccine presents itself.
