Pope Francis has received the coronavirus vaccine, according to Vatican sources.
It comes just days after the Pontiff's close personal doctor died of Covid-19 complications.
The 84-year-old received the jab in the atrium of the Paul VI Hall, according to reports.
He was one of the first in the Vatican to be inoculated with the Pfizer and BioNTech vaccine, La Nacion reported.
The Pope is due to receive the second dose in three weeks.
He had recently revealed he would get the injection as part of a vaccination programme at the Vatican, and said “ethically everyone should receive the vaccine”.
The head of the Catholic Church said people who refused take it despite it being known to be safe possessed a “suicidal denialism”.
In an interview with TV station Canale 5, he said: "I believe that ethically everyone should take the vaccine.
"It is an ethical choice because you are gambling with your health, with your life, but you are also gambling with the lives of others."
He added: "Next week we will begin to do it here, in the Vatican and I have reserved a shift. It has to be done."
Earlier this week, the Vatican announced the Pope’s personal doctor Fabrizio Soccorsi, 78, had died of complications related to coronavirus.
At the time he was being treated in Gemelli Hospital for cancer.
The physician was named as the Pope's personal doctor back in August 2015.
He came from outside the Vatican and worked as his personal doctor for more than five years, travelling across the world on international trips.
The Pope is said to have thought a lot of his doctor.
During a visit to Fatima, Portugal in May 2017, he laid down two bunches of white roses by the Virgin Mary statue as a gesture to his doctor's daughter who was critically ill at the time, but has since passed away.
