Flu vaccines plentiful in PA this year

(Atlanta) -- About 135 million doses of influenza vaccine are expected to be available this year, which means everyone who wants a flu shot should be able to get one.

The traditional flu shot is a trivalent vaccine, which protects against the three most common strains of influenza in the world. But several manufactures are distributing a quadrivalent vaccine this year, which includes a fourth strain of the flu.

Doctor Joe Bresee of the Centers for Disease Control and Prevention says both are effective.

"For the most part, whether you get a trivalent or a quadrivalent vaccine doesn't matter so much," he says. "They are both likely to protect you against the flu viruses that you encounter in the community, and as a result CDC doesn't state a preference for getting one or the other."

The CDC recommends flu shots for everyone over six months of age. Bresee says those who get them are 50 to 70 percent less likely to get sick.
