• Vaccine should be administered according to the most recent version of the Recommended Child and Adolescent Immunization Schedule for ages 18 years or younger or the Catch-up immunization schedule for persons aged four months-18 years who start late or who are more than one month behind, as published by the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices. Schedules are available for print or download through www.cdc.gov/vaccines/schedules/index.html.
• Vaccine doses administered less than or equal to four days before the minimum interval or age are valid (grace period). Doses administered greater than or equal to five days earlier than the minimum interval or age are not valid doses and should be repeated when age appropriate. If MMR and varicella are not given on the same day, the doses must be separated by at least 28 days with no grace period.
• For additional information, please refer to the Ohio Revised Code 3313.67 and 3313.671 for school attendance and the ODH Director’s Journal Entry on required vaccines for child care and school. These documents list required and recommended immunizations and indicate exemptions to immunizations.
• Please contact the Ohio Department of Health Immunization Program at 800-282-0546 or 614-466-4643 with questions or concerns.
* Recommended DTaP or DT minimum intervals for kindergarten students are four weeks between the first and second doses, and the second and third doses; and six months between the third and fourth doses and the fourth and fifth doses. If a fifth dose is administered prior to the fourth birthday, a sixth dose is recommended but not required.
** Tdap can be given regardless of the interval since the last tetanus or diphtheria-toxoid containing vaccine. Children age seven years or older with an incomplete history of DTaP should be given Tdap as the first dose in the catch-up series. If the series began at age seven to nine years, the fourth dose must be a Tdap given at age 11-12 years. If the third dose of Tdap is given at age 10 years, no additional dose is needed at age 11-12 years.
*** The final polio dose in the IPV series must be administered at age four years or older with at least six months between the final and previous dose. Only trivalent OPV (tOPV) counts toward the U.S. vaccination requirements. Doses of OPV administered before April 1, 2016, should be counted (unless specifically noted as administered during a campaign). Doses of OPV administered on or after April 1, 2016, should not be counted. If any combination of IPV and OPV was received, four doses of either vaccine are required.
**** Recommended MCV4 minimum interval of at least eight weeks between the first and second doses. If the first dose of MCV4 was administered on or after the sixteenth birthday, a second dose is not required. If a pupil is in twelfth grade and is 15-years-old or younger, only one dose is required. Currently, there are no school entry requirements for meningococcal B vaccine.
