The recently approved (FDA 2-27-2021) vaccine produced by Janssen/Johnson & Johnson used abortion-derived cell lines in the design, development, production and lab testing. This Janssen/Johnson & Johnson vaccine is morally compromised and therefore unacceptable for any Catholic physician or health care worker to dispense and for any Catholic to receive due to its direct connection to the intrinsically evil act of abortion. No one should use or receive this vaccine but there is no justification for any Catholic to do so. Two morally acceptable vaccines are available and may be used. As always, no one is bound to receive this vaccine, but it remains an individual and informed decision.
