“The startling global resurgence of pertussis, or whooping cough, in recent years can largely be attributed to the immunological failures of acellular vaccines, School of Public Health researchers argue in a new journal article.”

Adding supporting evidence I’ve accumulated:
In November 2013, a study[2] was published which found, “In this study, we show nonhuman primates vaccinated with aP were protected from severe symptoms but not infection and readily transmitted Bordetella pertussis to contacts.” The FDA released a statement on the study.
In June 2015, a study [3] found,
…more research is necessary, but if our results hold, public health authorities may be facing a situation similar to that of polio, where vaccinated individuals can still transmit infection. … In light of current evidence and our results, we cannot dismiss the potential far-reaching epidemiological consequences of asymptomatic transmission of B. pertussis and an ineffective B. pertussis vaccine.
