Influenza

Annual vaccination is a safe and effective measure to protect against influenza and its complications and is recommended for all people aged 6 months and over.  Vaccination against influenza should ideally occur before the onset of each influenza season, when it becomes available, but should continue to be offered as long as influenza viruses are circulating and a valid vaccine is available.
