Your child's whooping cough vaccine may not be as potent as you think.
New research is exposing a possible gap in how vaccines protect your kids.
A study in the journal Pediatrics says protection against whooping cough starts to weaken a few years after kids get their final shot. That's usually around age four to six.
Kids aren't recommended to get another booster shot until age eleven or 12.
But now researchers say their seeing a spike in whooping cough cases between ages seven and ten.
The study says efforts to move up the booster shot age aren't likely to work because it is currently given at the same time as several other vaccines for kids.
