The Vatican City State said Tuesday that it will require all employees to provide proof of vaccination or documentation of a recent negative COVID test, the Washington Post reports.

Why it matters: Pope Francis, who was vaccinated in January, has campaigned for people to get the shots, calling it a moral duty. Some Catholics, however, have argued for exemptions on religious grounds.

-Employees without proper documentation will be considered "unjustly absent" and receive no salary, per the Post.

-The Vatican is not allowing exemptions at the moment, though the Secretariat of State and the city-state's health department will review the issue.

-The new policy goes into effect on Oct. 1.
