Pertussis, or whooping cough, is making a comeback in California after cases dipped for a couple of years since the 2010 epidemic.
Some of the reasons have to do with fewer parents opting to have their children undergo public school vaccinations, and the cyclical nature of the disease. Also, researchers have found that the newer pertussis vaccinations don’t keep kids immune for as long as the previous vaccine did. That vaccine was discontinued for safety reasons.
