Back to School Immunizations

2020 - 2021 School Immunization Requirements

The Indiana State Department of Health Immunization Division annually reviews and updates the immunizations required for school entry.  Changes to the 2020-2021 School Immunization Requirements are as follows:
  • Hepatitis A.  Two (2) valid doses of Hepatitis A vaccine (Hep A) are required for students in all grades, including schools with pre-kindergarten programs, beginning in the fall of the 2020-2021 school year.  
  • Varicella. Physician documentation of disease history, including month and year, is proof of immunity for students in preschool through 12th grade.  Parental report of disease history is not acceptable
  • Polio vaccine.  For students in grades K-10, the final dose must be administered on or after the 4th birthday and administered at least 6 months after the previous dose.  
  • All other requirements from the 2019-2020 School year will remain unchanged.
The full list of all school immunization requirements can be found on the Indiana State Department of Health’s Immunization website at

Other immunizations your physician may recommend for adolescents (if not already given):

  • HPV vaccine- recommended for both boys and girls starting at age 11 to prevent cervical, vulvar, and vaginal cancers in girls and anal, oropharyngeal and other head and neck cancers caused by human papillomavirus (HPV) in both boys and girls.  New recommendations adopted in December 2016 has changed the number of doses required depending on age when the series is started.  Talk to your health care provider for more information.
  • Meningitis B vaccine- this two (2) shot series is recommended for ages 16-18 years to prevent Meningococcal disease (Neisseria meningitidis) which causes meningitis and infections of the blood. This has been the cause of recent outbreaks at colleges and universities.  The college or university your child will attend may require this vaccine.  Check their immunization requirements.

What should parents do to make sure their children are properly immunized?

  • Check your child’s immunization record.  It is possible your child has already received these vaccines.
  • If your child has received the vaccines, give the immunization record to the school nurse. Ask your healthcare provider to put immunizations into CHIRP, the statewide immunization registry.  This will prevent unnecessary immunizations from being given. 
  • If your child has not received the vaccines, schedule an appointment with your primary care provider.  Remember to schedule your appointment early to avoid the last-minute rush.
These changes will continue to help Indiana prevent further disease outbreaks that have occurred in our state in recent years.
