You'll only need a single shot of influenza vaccine this year to protect against three strains of the flu, including the H1N1 virus that sparked the 2009 pandemic.

The federal Food and Drug Administration today approved vaccines for the 2010-2011 flu season, and they include drugs to protect against H1N1, another strain of influenza A, Perth, and a strain of influenza B, Brisbane.

The news comes as the Centers for Disease Control and Prevention officials have announced expanded recommendations that urge everyone older than six months get a seasonal flu shot.

Manufacturers expect to produce about 170 million doses of the new seasonal vaccine, which is higher than the 100 million doses offered in a typical flu season, but lower than the nearly 200 million doses of H1N1 vaccine ordered by the government last year, said Tom Skinner, a spokesman for the Centers for Disease Control and Prevention
