ROME — The Vatican is now requiring a coronavirus health pass for anyone who wants to enter the city state or see the Sistine Chapel.

Starting Oct. 1, Vatican residents, employees and visitors must show proof that they were vaccinated against COVID-19 or were cured of it, or have had a negative test result, in order to gain access to the walled city state in the center of Rome that is home to the Vatican Museums.

The decree published Monday contains an important exception: People coming to St. Peter’s for a Mass don’t have to show the so-called “Green Pass,” but must observe social distancing and mask requirements and stay only for the duration of the service.

The provisions follow moves by Italy to require the “Green Pass” for indoor activities, such as dining indoors and seeing movies, as well as for all public and private workers to enter their workplaces.

Pope Francis has been a keen proponent of vaccines and has urged widespread vaccination as an “act of love” toward other people.
