That is just it. It "trains" your immune system so that if you encounter that strain, the system already knows what to do. That speeds up the reaction a lot as opposed to the body "learning" at the time of an infection.
Here is a little trick my wife did while studying pharmacology. Every drug will print out their laundry list of symptoms. Pretty much boilerplate. So, if you name them all from head to toe, you will get it right. Certain drugs will have their own peculiar side effects. So, if you list out all the stuff, you will get it right. You have to remember some unique ones like say blue spots in your vision with viagra. Say you are talking about Cialis, Viagra or Levitra, you might get priapism in which case, you are to consult your local hooker or doctor. Either way, you can tack on the rest of the side effects that you memorized for this and all other drugs.
