Immunization Requirements & Information

Any student attending Platte County R-III must be in compliance with the Missouri state laws regarding immunizations. Students not in compliance with the law will NOT be permitted to enroll, attend, or participate in any school activity. A student is considered in compliance with the law if:

  • All immunizations are complete and the dates are provided to the school.
  • The immunization process has started and is progressing according to the schedule recommended by the Missouri Department of Health.
  • An exemption from immunization has been arranged according to the provisions of the law.  See health.mo.gov for more information. 

Parents are responsible for providing dates (day, month, and year) of all immunizations previously received when a student is enrolled. Exclusion from school, as required by the law, will occur if the student is not adequately immunized, or properly exempted.
