ATLANTA (AP) — An expert panel is urging every expecting mother to get a shot preventing whooping cough, preferably in the last three months of her pregnancy to help protect her baby.

The advice follows a frightening resurgence of the dreaded childhood disease. More than 32,000 cases, including 16 deaths, have been reported so far this year, and 2012 is on track to be the nation’s worst year for whooping cough since 1959.
