Immunization Requirements

  • According to Missouri immunization laws, students are not allowed to attend classes unless all required immunizations have been received or if the student is in the process of obtaining immunizations, in which a Missouri state “immunizations in progress” form (ImmP.14) must be presented to the school nurse. Parents/guardians must provide written proof (an official immunization record) of compliance to the school nurse by the first day of school. Exemption from immunizations is allowed for religious or medical reasons. Please contact the St. Louis County Department of Health or your physician if you need an exemption form for medical or religious reasons.

    If you have any questions or concerns regarding the immunization requirements for school attendance, please contact your school nurse or the St. Louis County Department of Health.
