whooping cough vaccineA study published in the New England Journal of Medicine has found that protection from whooping cough wanes quickly after the final dose of the vaccine is administered to children around age seven.

Most children whose parents chose to follow the recommended schedule receive the vaccine in five doses beginning as an infant. Acellular pertussis is just one of the three vaccines contained in this DTaP series, which also includes diphtheria and tetanus.

The new results showed a dramatic drop in continuing protection from the vaccine after the final dose is administered. "The odds of acquiring pertussis increased by an average of 42% per year," states to the study.

The report has added a new consideration in the ongoing question of why whooping cough has been on the rise in the US.

"Spotty vaccination rates are a problem in some places, like California, where whooping cough has roared backed recently. But the weakness of the current vaccine appears to be another factor in the resurgence of whooping cough," reports NPR.
