They would still evolve with or without vaccines. If there are fewer flus then there are fewer opportunities for the damn thing to evolve.
Influenza is a small, plastic virus. It shares dna with other virus very easily - making it very dangerous. The "flu shot" is a cocktail of different vaccines selected every year by government doctors who try to find out which ones are new (probably more dangerous) or most prevelent.
Bottom line: more people get flu vaccines, the less influenza out there, then fewer opportunities for the thing to evolve. Unfortunately there are many squalid places on earth where not everyone can get the shot (and not to mention other animals get the flu) so they continue to evolve.
