Influenza is caused by a highly contagious virus that is spread by contact with fluids from coughs and sneezes. Annual immunization is recommended for seniors and other people who are at risk of serious complications from the so-called flue.
Influenza virus changes every year because it has unique ability to change its surface structure. Each year a new vaccine is developed and is available for those who wish to be immunized. Recent evidence suggests protection against influenza may start to decrease from three to four months following vaccination. Annual vaccination before the onset of each influenza season is recommended. While influenza continues to circulate it is never too late to vaccinate.
