Each season's flu vaccine is targeted at 2 to 3 strains of influenza virus that surveillance teams have identified as the likely ones that will hit in a particular season. Sometimes they guess wrong. Since it takes such a long time to manufacture a vaccine, there isn't time to correct if they do guess incorrectly.
Even when they get it right, you could still get sick. All the vaccine does is trigger your immune system. If the response isn't strong enough, you could still be susceptible.
