Study: Whooping Cough Vaccine Weakens Over Time
by News


The vaccine against whooping cough may not be as effective for children as once thought.

A new study in the New England Journal of Medicine indicates that in the planned series of shots, the vaccine is less effective each year after the most recently administered shot.

The final shot is given around age six, and then a tetanus booster is recommended about five years later.
