Get a Flu Vaccine Every Flu Season
Almost everyone should get vaccinated every year for two reasons. First, because flu viruses are constantly changing, the flu vaccine is often updated from one season to the next to protect against influenza viruses that research indicates will be most common during the upcoming season. Second is that a person's immune protection from vaccination declines over time so a yearly vaccination is needed for optimal protection. Yearly vaccination is recommended even for those who received the vaccine during the previous flu season.
