Can you still get influenza after getting the influenza shot?

Yes, however the severity of the symptoms will be less than if you had not received the vaccine. In healthy people, the vaccine provides a good level of coverage against influenza, which usually starts 2 weeks after vaccination. 

In those who do contract influenza even after having the vaccination, the symptoms tend to be less severe and people are less at risk of developing more serious complications, which may lead to hospitalisations or even death.  

Speak with a healthcare professional about your vaccination needs.
