Flu vaccine less effective than hoped

(NEWSCHANNEL 3) - Troubling information came out this week surrounding the flu vaccine.

Health leaders say this season's flu shot is only 9 percent effective in protecting seniors against the most common and dangerous flu bug.

For all age groups, the vaccine's effectiveness was a moderate 56 percent.

The flu vaccine tends to protect younger people better than senior citizens and is never 100 percent effective.

Experts say, however, that the preliminary results released Thursday are disappoinging and highlight the need for a better vaccine.
