• Immunization Requirements

    NEW As of Aug 31, 2018

    Immunization Rules For 11Year Olds 

    Arizona Department of Health Services has made changes to rules for age requierement for Tdap and Meningococcal Vaccines for school attendance which will affect your students as they turn 11 years old.

    Tdap (tetanus, diphtheria, attenuated pertussis) will be required for students as they turn 11 years old and older when 5 years have passed since the last tetanus/diphtheria vaccine dose (DTP, DTaP, or Td). Previously, a Td was done 10 years after the initial series completed, but recurrence of pertussis in the teen population over the past years has put children at increased risk for this life-threatening disease. This is required as they turn 11 even if they are not in the 6th grade.   MV (meningococcal vaccine) will be required for students who are 11 years old, even if they are not in 6th grade yet.  Meningococcal meningitis can be highly contagious in teen and young adults and may result in severe disability if not death. Students entering 6th grade must have documentation of these immunizations prior to the beginning school year each Fall if they are already 11 years old.

    As you update your child's immunizations, please get the Tdap and MV administered and documented as soon as possible when your child turns 11 years old. Please get that documentation to my office when completed so that school records can be updated.

    The laws and rules governing school immunization requirements are Arizona Revised Statutes §15-871-874; and Arizona Administrative Code, R9-6-701–708. Please review the school requirements in Table 7.1 and “catch-up” schedule in Table 7.2, located in R9-6-701-708. 


    Students must have proof of all required immunizations in order to attend school. Parental recall or verbal history of any disease is not accepted; therefore these students must submit an ADHS medical exemption form. Specifically with varicella (chickenpox), measles, or rubella disease a medical exemption with attached laboratory evidence of immunity is required.  Arizona law allows K-12 immunization exemptions for medical reasons, lab evidence of immunity, and personal beliefs. 


    Homeless students and children in foster care are allowed a 5-day grace period to submit proof of immunization records (assuming that all other students have their immunization records submitted prior to attendance at school).


    For further information and guidance please review the Arizona Immunization Handbook for Schools and Child Care Programs along with Frequently Asked Questions.


    Quick-Look Vaccine Exceptions and Conditions


    • Hepatitis B – A child has received the required number of doses of hepatitis B virus (HBV) vaccine to qualify for Arizona school and child care/preschool attendance if all of the following apply:


    • There are at least 4 weeks between the 1st and 2nd dose of HBV vaccine;
    • There are at least 8 weeks between the 2nd and final dose of HBV vaccine;
    • There are at least 16 weeks (4 months) between the 1st and final dose of HBV vaccine;
    • AND the child received the final dose of HBV vaccine when they were at least 24 weeks of age.


    • Hepatitis B for students aged 11-15 years – 2 doses meet the requirement if adult hepatitis B vaccine (Recombivax) was received. Dosage (10mcg/1.0mL) and type of vaccine must be clearly documented.  If Recombivax was not the vaccine used, a 3-dose series is required.


    • Meningococcal Vaccine – Only quadrivalent meningococcal ACWY vaccine doses will be accepted. The only quadrivalent meningococcal vaccines given currently in the U.S. are Menactra and Menveo. The Meningococcal Polysaccharide vaccine (Menomune) was a quadrivalent vaccine so is acceptable; however, production of this vaccine was discontinued in February 2017. Students who received this polysaccharide vaccine are considered acceptable for school requirements. No monovalent or bivalent meningococcal vaccinations will be accepted (MenA, MenB, MenC, or MenC/Y).


    • Poliomyelitis (Polio) – The U.S. currently does not give anything other than IPV (inactivated polio vaccine) whereas some foreign countries still give the OPV (oral polio vaccine). OPV given prior to April 1, 2016 will be presumed to be trivalent and therefore acceptable, regardless of country of administration. Any OPV doses administered after April 1, 2016 are presumed to be bivalent and therefore unacceptable.


    • Td Booster – A Td booster is required 10 years after the last dose of a tetanus-containing vaccine if student is still enrolled in school.
