Data Show Many People With Pertussis Received Vaccine
An investigation of whooping cough, or pertussis, cases in California and other states has revealed that many individuals whoÂ contracted the disease had received vaccinations. KPBS and the Watchdog Institute -- a not-for-profit group based at San Diego State University -- found that, in pertussis cases where inoculation histories were known, between 44% and 83% of individualsÂ had received a whooping coughÂ immunization in nine California counties with high rates of infection. As of Dec. 15, state health officials said there were 7,824 reported cases of whooping cough.
