Guide to Immunization Requirements for Oklahoma 

Vaccines Recommended for All Children but Not Required by Oklahoma School Law

  • A 2nd dose of varicella (chickenpox) vaccine is recommended at 4-6 years of age and at any age after that if it is missed at 4-6 years.
  • One dose of MCV4 (meningococcal vaccine) is recommended at age 11-12 years and a booster dose at 16 years of age.
  • If an adolescent misses MCV4 at 11-12 years, they should still receive it. This vaccine is routinely recommended up to 18 years and through age 21 years for first year college students living in dormitories or on-campus student housing because of their risk of catching the disease.
    If an adolescent receives the first dose of MCV4 late at 13 through 15 years, they still need a booster dose at age 16 through 18 years.
  • Oklahoma law requires a dose of MCV4 for all students who are first-time enrollees in any public or private postsecondary educational institution in this state and who reside in on-campus student housing. It is recommended they receive a dose on or after the 16th birthday.
  • Three doses of HPV (human papillomavirus) vaccine are recommended starting at 11-12 years of age. If an adolescent misses HPV at 11-12 years catch-up vaccination is recommended for all girls.
