North Carolina’s immunization rate is one of the highest in the nation. The only way parents can ask for exemption is with a letter signed by a physician.

The U.S. Centers for Disease Control and Prevention issued a health advisory this month about an ongoing measles outbreak, with more than 102 cases in 14 states so far. The highly contagious disease can cause severe health complications, including pneumonia, encephalitis and death.
By 2000, measles had been nearly wiped out in the U.S., with fewer than 60 cases per year, most connected with foreign travel. Public health officials declared victory, the result of effective state-based immunization campaigns requiring kids to be vaccinated before they enter public schools.
Since then, however, the number of cases has risen along with the number of parents who have received religious or philosophical exceptions to state rules. In 2014, there were at least 23 outbreaks and more than 600 cases.
The federal government’s goal is to immunize at least 90 percent of all children before they enter school to keep measles and other childhood diseases at bay. Although the national average immunization rate (91.1 percent) exceeds that number, several states fall below it.
“To have pockets where community immunity is below 90 percent is worrisome, as they will be the ones most vulnerable to a case of measles exploding into an outbreak,” said Litjen (L.J) Tan, chief strategy officer of the Immunization Action Coalition, which advocates for higher levels of immunization.
State immunization rates vary widely, with generally lower rates of inoculation occurring in states that make it relatively easy to get an exception. Lawmakers in California, Oregon and Washington state are trying to tighten their laws to allow fewer nonmedical exemptions. Laws allowing religious exemptions have been around longer than those allowing philosophical or “personal belief” exemptions, said Joy Wilson of the National Conference of State Legislatures.
In many but not all states, philosophical exemptions are easier to get than religious exemptions, which typically require parents to cite and explain the religious doctrine in question. Overall, states with philosophical exemptions have 2.5 times the rate of opt-outs than states with only religious exemptions.
