Influenza is a serious disease.
It can result in pneumonia, hospitalization or even death, especially in the elderly and those with chronic illnesses. Annual immunization against the flu is the best protection for you and those in your care. The chance of an outbreak of influenza in a health care facility is much lower if most staff and residents are vaccinated. The viruses that cause the flu change often. Because of this, the flu vaccine is updated each year by replacing at least one of the vaccine viruses with a newer one.
