A London-born teenager is set to become the first millennial to be made a saint after he has had a second miracle attributed to him by Pope Francis.

Carlo Acutis, who died of leukaemia in 2006, aged 15, was beatified in 2020 after appearing to have cured a Brazilian boy, Mattheus Vianna, of a serious birth defect which left him unable to keep down his food.

That miracle, which dates back to February 2014, saw the boy being “fully cured” after he touched Carlo’s relic and said “stop vomiting”, a priest and family friend of Mattheus’s said.

The second miracle saw a girl from Costa Rica who was studying in Italy reportedly being healed after suffering a head trauma.

She was reportedly cured by the boy after he was invoked by her mother, Avvenire, the daily newspaper of the Italian Bishops’ Conference (CEI), reports.

Pope Francis took the decision to attribute the second miracle to Carlo during a meeting with the head of the Vatican’s saint-making department, Cardinal Marcello Semeraro.
