State health officials say North Dakota's immunization rate for kindergarteners remains at about 94 percent for all required vaccines.

The information is from the Department of Health's 2017-2018 school immunization assessment. Health department epidemiologist Lexie Barber says a 95 percent rate is the goal which is recommended to maintain immunity in schools and prevent outbreaks.

The immunization rate has climbed in the last two years after previous years of being at, or below 90 percent.

Before entering school in North Dakota, children must have five doses of Diphtheria, Tetanus and Pertussis; four doses of the polio vaccine; three does for hepatitis B and two doses each for MMR and chickenpox.
