All immunizations should be completed by the first date of attendance. The law requires that students be fully vaccinated against the specified diseases.
A student may be enrolled provisionally if the student has an immunization record that indicates the student has received at least one dose of each specified age-appropriate vaccine required by this rule. To remain enrolled, the student must complete the required subsequent doses in each vaccine series on schedule and as rapidly as is medically feasible and provide acceptable evidence of vaccination to the school.
A school nurse or school administrator shall review the immunization status of a provisionally enrolled student every 30 days to ensure continued compliance in completing the required doses of vaccination. If, at the end of the 30-day period, a student has not received a subsequent dose of vaccine, the student is not in compliance and the school shall exclude the student from school attendance until the required dose is administered.
