For the first time, certain vaccines will guard against four strains of flu rather than the usual three.
Called quadrivalent vaccines, these brands may prove more popular for children than their parents. That's because kids tend to catch the newly added strain more often. And for the first time this fall -- places like the Fresno County Department of Health and the Veterans Hospital of Fresno will carry the shots.
These four-in-one vaccines are so new they'll make up only a fraction of the nation's supply of vaccine, so if you want a dose, better start looking early.
Other options available this year include egg-free shots some brewed just for the 65-and-older crowd, and a brand that targets the needle-phobic with just a skin-deep prick. But not every hospital, doctor or retail healthcare center will carry all seven varieties.
