Vaccine Controversies - Religion

Religion

Vaccination has been opposed on religious grounds ever since it was introduced, even when vaccination is not compulsory. Some Christian opponents argued, when vaccination was first becoming widespread, that if God had decreed that someone should die of smallpox, it would be a sin to thwart God's will via vaccination. Religious opposition continues to the present day, on various grounds, raising ethical difficulties when the number of unvaccinated children threatens harm to the entire population. Many governments allow parents to opt out of their children's otherwise-mandatory vaccinations for religious reasons; some parents falsely claim religious beliefs to get vaccination exemptions.

The cell culture media of some viral vaccines, and the virus of the rubella vaccine, are derived from tissues taken from therapeutic abortions performed in the 1960s, leading to moral questions. For example, the principle of double effect, originated by Thomas Aquinas, holds that actions with both good and bad consequences are morally acceptable in specific circumstances, and the question is how this principle applies to vaccination. The Vatican Curia has expressed concern about the rubella vaccine's embryonic cell origin, saying Catholics have "...a grave responsibility to use alternative vaccines and to make a conscientious objection with regard to those which have moral problems." The Vatican concluded that until an alternative becomes available it is acceptable for Catholics to use the existing vaccine, writing, "This is an unjust alternative choice, which must be eliminated as soon as possible."
