Children who skip vaccinations raise threat of dangerous outbreak

An Arizona Star investigation has found that “one in three Arizona schools last year had kindergarten classes with vaccination rates so low children were left vulnerable to infectious disease outbreaks such as measles, mumps or pertussis.”

It was discovered that “the worst offenders, by far, are charter and private schools, some with vaccination rates as low as 50 percent in Pima County and under 30 percent in Maricopa County. Rates need to be 80 percent to 95 percent, depending on the disease, to prevent the spread of infection.”
