Pope Francis was up and receiving therapy on Monday after apparently overcoming a setback in his recovery from pneumonia.

Pope Francis suffered two new acute respiratory crises Monday and was put back on noninvasive mechanical ventilation, in another setback to his battle to fight pneumonia, the Vatican said. Doctors extracted “copious” amounts of mucus from his lungs during two bronchoscopies,

The Vatican said the mucus was the body’s reaction to the original pneumonia infection and not a new infection, given laboratory tests don’t indicate any new bacteria. Francis remained alert, oriented and cooperated with medical personnel.
