Arizona law requires documentary proof of immunity against certain childhood diseases for students entering Arizona schools for the first time. With some exceptions, students subject to this requirement who lack documentary proof may enroll but not attend school until proof is provided. If your child falls into this category, more detailed information is available at the school.

Immunization requirements and free clinics are listed on the Health Services Web page. Call the Maricopa County Health Department's hot line at (602) 263-8856 for other sites and times. Immunizations are also available from family physicians and pediatricians.
