For one to be canonized as a saint,
two healing miracles must be proven through intercessory prayer

In 2013, at a church in Campo Grande, Brazil, a Mass and intercessory prayer service for the beatification of Carlo Acutis were held along with his relics. At that time, Matheus, a four-year-old boy, was depended entirely on liquid nutrition due to a congenital pancreatic defect. Doctors had diagnosed that long-term survival was unlikely. "I hope I stop vomiting now," Matheus prayed fervently during the intercessory prayers at the church with his mother. On the way home, Matheus told his mother that he was already healed, and that evening, he was able to eat solid food for the first time in his life. Later, doctors declared him fully cured.

In July 2022, Valeria, an 11-year-old girl from Costa Rica living in Florence, Italy, suffered a severe skull injury in a bicycle accident and underwent emergency brain surgery. The prognosis was very poor, with low chances of survival. Her mother immediately traveled to Assisi and prayed fervently at the tomb of Blessed Carlo Acutis, where his mortal remains are preserved. Remarkably, that very night, Valeria began to breathe on her own and regained her speech abilities. She was discharged from the intensive care unit within 10 days and, a month later, was released from the hospital with no signs of brain hemorrhage remaining.
