It seems there is a moral obligation, for one is obligated to care for one’s own body and to care likewise for the body of the neighbor, who by divine command is to be loved as oneself. Now, vaccination may render one’s own body less likely to succumb to a viral infection and less likely to pass on such an infection to the potential harm of the neighbor. Therefore one ought to be vaccinated. As Vitoria says ( On the Law of War, Q. 2, art. 2), “any person who has the power to prevent his neighbor’s danger or loss is obliged to do so.”
