Pneumonia - Diseases
Pneumonia is not a specific disease. It is a general term for several kinds of inflammation of the lungs. Pneumonia is usually caused by a bacterial or viral infection, but it can also be caused by chemical damage to the lungs from inhaling a poisonous gas such as chlorine. Ref. Source 5
The end of pneumonia? New vaccine offers hope. A new vaccine under development provoked an immune response to 72 forms of the bacteria that's responsible for pneumonia, sepsis and meningitis. That's up from the 23 forms of bacteria covered by current immunizations. The new vaccine, which represents the 'most comprehensive' coverage of pneumococcal disease to date, could greatly reduce the number of deaths from the disease. Source 5j.
