Are Christians morally obligated to be vaccinated for COVID-19?

As the COVID-19 pandemic persists and new vaccine boosters targeting the latest subvariants have been approved, public debate concerning vaccines and vaccination mandates has not subsided. Such debate has been particularly acute among Roman Catholics and other Christians, with arguments having been put forth from scriptural and natural law bases in favor of vaccination against COVID-19, and counterarguments based on respecting individual conscience and concerns about moral complicity with abortion. In this article, I argue that principles of both secular public health and Christian social ethics justify vaccination mandates for COVID-19. I further show why certain objections Christians may have are ill-founded and conclude that no moral reason exists for a Christian to refuse to be vaccinated for COVID-19; rather, vaccination for COVID-19 is a moral obligation.
