Last year's flu vaccine was not a great match for the strains that made people sick. It only protected people about 23 percent of the time. But, this year's flu shot appears to be working a lot better.

Doctor Dean Blumberg is the chief of pediatric infectious diseases with UC Davis.

"My message this year it can't be as bad as last year, it's got to be a better match. And, there will be some protection from the vaccine. And, since the flu season is running late this year it's not too late to get your shot and get protection," says Blumberg.

Blumberg says a successful influenza vaccine will prevent the flu about 60 to 80 percent of the time. 

He also recommends getting enough rest, staying hydrated and eating healthy to prevent illness. 

"That can't be emphasized enough really about adequate hand washing either with soap and water. Make sure you so it enough -- for at least twenty seconds. Or, the alcohol based hand gels are excellent."
