Unvaccinated children helped fuel whooping cough outbreak, data show
Los Angeles Times

Children who did not get vaccinated against whooping cough contributed to the 2010 outbreak of the illness, when more cases were reported than in any year since 1947, researchers say.

Researchers who looked at the geography of the cases suggest that clusters of “nonmedical exemptions” to immunizations were one of several factors in the California outbreak. They reported their findings Monday in the journal Pediatrics.
