From Canadian Conference of Catholic Bishops
The decision to receive any COVID-19 vaccine is one of individual conscience in consultation with one’s physician or healthcare provider. Choosing to be vaccinated, particularly amid the current pandemic, can be an act of charity which recognizes the need to care for others.
The CCCB echoes the call of the Holy See,1 by reiterating its appeal to governments to “ensure that COVID-19 vaccines that become available do not create an ethical dilemma for Canadians,”2 thus encouraging greater vaccine uptake among the general population and strengthening the common good of our Canadian society.
The recent approvals by Health Canada of the AstraZeneca and Johnson & Johnson vaccines against COVID-193 have given rise to questions among Catholics about the moral permissibility of receiving vaccines whose development, production, and/or testing has involved the use of abortion-derived cell lines. These questions are important for they concern the sacredness of human life and its inherent dignity.
The Moderna and Pfizer vaccines already approved in Canada do not use abortion- derived cell lines in their development and production of the vaccine, however in some of their final testing processes, they have used unethically-derived cell lines. These two vaccines currently available in Canada can be morally acceptable for Catholics to receive since the connection to abortion is extremely remote.
