There is a new flu-fighting weapon in our arsenal this year. Like its name suggests, the quadrivalent flu vaccine protects us from four strains of the flu. Usually, a vaccine covers three strains.
However, quadrivalent shots are in short supply. Those at the Centers for Disease Control and Prevention say they account for only 30 million of this year's 140 million shots.
Abc27 also learned the new shot is more expensive and is relatively tough to come by. We tracked it down at a Giant food store in Susquehanna Township. Even there, they have only a handful available. Without insurance, the new shot would run you $40.
So is the new vaccine better? Health officials don't believe so.
"The CDC has not stated that one should be considered superior to the other," said Dr. Carrie DeLone, Pennsylvania's physician general.
It sounds like either will do the trick. DeLone also said that if you are really set on upping your flu-fighting odds, you might opt for the nasal spray.
"If you got the nasal-inhaled preparation, you have gotten the quadrivalent," DeLone said.
