To avoid ordering multiple types of flu vaccine we have chosen the vaccine that would suit the needs of the majority of our patients, the standard dose trivalent vaccine. Some patients have asked about the high dose vaccine–it contains much more antigen than the standard dose, but studies so far show that it is no more effective, or may be only marginally better, depending on which study one reads.
