The Vatican’s statement on the COVID-19 vaccine includes consideration of what constitutes ordinary means of preserving life. In the statement, to which I referred in earlier posts, the Congregation for the Doctrine of the Faith said that vaccination is not morally obligatory. That statement is accurate in light of the moral teaching of the Church on conserving one’s life. It is a complex issue but we must accept the fact that the question of treatment, including prevention of the spread of disease, does involve one’s personal prudential judgment that cannot be negated by force. The article that I reference here might be of some help. It does not address the question of vaccinations directly. The basic principles are the same.
