Study examines flu vaccine effectiveness

Flu season is here and some doctors are warning the flu vaccine may not provide enough protection.

Findings from a new study at the University of Minnesota suggest the injectable vaccine protects adults at a rate of about 59 percent and didn't protect children or seniors.

The study also found that the nasal spray vaccine offered protection 83 percent of the time for adults and showed no evidence of protection for children or seniors.

Doctors say the flu shot is still the best defense we have.
