In this populace, the shot can be fifty to sixty percent effective in stopping hospitalization or pneumonia and eighty percent successful in stopping flu related death. Among old people not residing in chronic-care facilities and persons with long-term medical conditions, the flu shot is thirty to seventy percent successful in stopping hospitalization for influenza and pneumonia.

The ability of a flu vaccine to shield a person varies based on the age and health status of the person receiving the vaccine, and the "match" between the viruses or virus in vaccine and those in the air.
The flu shot itself is extremely efficient for the strains of the virus it entails. Even so, as long as you don't mind possibly getting the flu, the flu shot is not technically necessary for people who aren’t kids or elders. The majority of people can fight off a simple flu virus in 7 days. The immune systems of children and old people are not quite as strong as that of middle-age people, and therefore they are more likely to contract the disease.
