This year’s flu vaccine isn’t very effective.

The CDC says it only protects against the flu 23-percent of the time.

That’s much lower than previous years, where effectiveness has ranged from 50 to 60-percent.

Experts predict which vaccine to use months before the flu season starts, to give manufacturers time to make it.

The CDC says those predictions were way off this year.

They still recommend getting the vaccine though, because some protection is better than no protection.
