A new survey shows Whatcom County has a higher percentage of parents who opt out of school immunization requirements for their children than the rest of the state.
5.9 percent of local parents rejected one of more vaccines for their kindergartners during the last school year.
That's above the statewide average of 4.5 percent.
Michele Roberts with the state Department of Health says some parents still have concerns about vaccines, but she says immunizations are one of the best ways to protect kids from 14 serious diseases.
Seventy-five percent of children ages three and under got all of their recommended vaccines in 2011, up from 71 percent in 2010 according to the National Immunization Survey.
Immunization rates for whooping cough increased from 82 percent to 86 percent.
