Keeping up to date with vaccines is important in maintaining good health for older adults. These immunizations do not guarantee that a person will not get sick with these conditions, but they make it less likely and reduce the risk of severe infection or death. Flu is a viral infection that causes symptoms such as fever, headaches, body aches and pains, sore throat, and cough. It is very easily passed from one person to another. People who get flu then often develop pneumonia.
Many older adults die each year from complications of flu.
Pneumococcal disease is an infection caused by a certain type of bacteria. The vaccine does not prevent pneumonia caused by other types of infection. Bacteria that enter your body through a break in the skin cause tetanus, or lockjaw. Diphtheria, also caused by a bacteria, can cause serious problems when the bacteria release a poison into the bloodstream. The shot is also recommended for younger people with chronic diseases and those who want to avoid the flu.
