EDS: Clients who used a Cronkite News story slugged  BC-CNS-Vaccination Rate that moved Friday, April 12, under a PHOENIX dateline, are asked to run the following correction. The error occurred in the 8th graf of the original. A corrected version of the story has been posted here.

PHOENIX – A Cronkite News story about a decline in vaccination rates was misleading about state requirements. Vaccines are mandatory for all grade levels, but the Arizona Department of Health Services only requires schools to report immunization rates for students in preschool, kindergarten and sixth grade unless a doctor exempts them because of medical reasons or a parent exempts them because of personal, philosophical or moral objections.
