Yes, I agree, vaccination is not 100% proof against the flu.  It won't even give 100% protection against even the flu strains it's made for. 
A condom won't always prevent HIV or other STD's. 
Proper screening won't prevent all bad clients.
Locking your front door won't prevent every possible break in to your home. 
A seat belt won't save your life in every single accident. 
A smoke detector won't always save your life in case of a fire. 
Eating healthy and exercising won't prevent every heart attack or cancer.  
A good anti-virus program won't prevent every possible computer virus. 
Not drinking and driving won't prevent all car accidents. 
They're all still really good ideas.
