What is Pope Francis's current health condition and why is it concerning?

Pope Francis is currently suffering from pneumonia, which has raised serious health concerns and forced him to miss key Vatican events during this Jubilee year. His condition is significant enough that the Vice President of the United States has publicly called for prayers, tweeting: "let's all say a prayer for Pope Francis who appears to have some serious health issues." The Pope's health situation is particularly concerning given the timing, as major Catholic holidays are approaching. His absence during this special Jubilee year of the Catholic Church adds further significance to his health struggles, making this a developing story of importance to the global Catholic community.
