Your risk of pneumonia may be higher because of your age, environment, lifestyle habits, and other medical conditions.
Pneumonia can affect people of all ages. However, two age groups are at higher risk of developing pneumonia and having more serious pneumonia.
Babies, children, and older adults who do not get the recommended vaccines to prevent pneumonia have an even higher risk.
