Why do I need to get vaccinated against the flu each year?

There are two main reasons for getting an influenza vaccine every year, to give you the best protection:

  • Flu viruses are frequently changing and vaccines may be updated from one season to the next to protect against the most recent and common circulating strains
  • A person’s immune protection from influenza vaccination declines over time and annual vaccination is recommended.
