The Vatican carried on with its Holy Year celebrations without the pope Saturday, as Pope Francis battled pneumonia and a complex respiratory infection that doctors say remains touch-and-go and will keep him hospitalized for at least another week.

Doctors on Friday said the 88-year-old Francis is "not out of danger" ​and that the main threat facing him would be the onset of sepsis.

The 88-year-old pontiff, who was admitted to the hospital last week, is being closely monitored by doctors as he undergoes treatment.
