Influenza
viruses change frequently and infection with one strain does
not provide protection against all strains. |

The
Disease
Influenza, known more
commonly as "the flu," is caused by the influenza virus, which
infects the respiratory tract (nose, throat, and lungs). Unlike many other
viral respiratory infections, such as the common cold, the flu can cause
severe illness and life threatening complications in many people.

The
Immunization
Two types of influenza
vaccine are now available: inactivated (or killed) vaccine and live attenuated
(or weakened) vaccine.The inactivated influenza vaccine is given as a
shot and has been used in the United States for many years. The attenuated
vaccine, licensed in 2003, is given as a nasal spray. It is licensed by
the Food and Drug Administration (FDA) for healthy children and adults
from 2-49 years of age.
