Influenza, or the flu, is caused by a virus which spreads easily from person to person. You can catch it by inhaling infected droplets or by touching contaminated objects and then your nose or mouth.1
The flu vaccine contains an inactive form of the virus. When injected, this virus induces you to make antibodies that protect you against strains of influenza expected to circulate in the coming flu season.
For some groups of people, catching the flu can result in serious complications.1 By studying recent influenza outbreaks (including the 2009 H1N1 pandemic), we now know a lot more about how to prevent and manage the flu. With a simple vaccination, you can protect yourself and others around you from catching it. For more information about the flu, click here.
The current flu vaccine contains extracts of protein from the H1N1 swine flu strain and from the two other most common flu strains. Once vaccinated, these proteins prompt your body to make antibodies to protect you from the virus.
This vaccine does not contain live virus and cannot give you influenza.2
How quickly you're protected after getting vaccinated varies from person to person. Generally, you'll start producing the antibodies that provide protection two weeks after vaccination. Protection is expected to last for at least one year,2 however, because the flu virus is constantly changing, it's important that you get vaccinated every year.
The best time to get the flu vaccination is in autumn, before the expected outbreak in winter. Each annual flu vaccine will protect you against the three or four strains of flu virus most likely to circulate that winter.
Everyone can get the flu vaccination. But those who are at serious health risk if they do catch flu are especially encouraged to do so.2
