What is currently happening with Pope Francis's health, and why is it concerning?

Pope Francis is currently battling pneumonia affecting both lungs, which has prompted serious health concerns. The Vice President of the United States has called for prayers, acknowledging the Pope's 'serious health issues' through a public tweet. These health complications are particularly concerning due to the timing, as major Catholic holidays approach during this Jubilee year. The Pope has canceled public appearances while the Vatican tries to balance transparency about his condition with maintaining a positive image, recognizing the challenges presented by his age and declining health.
