STAYING HEALTHY!
• Doses administered four days or less before the minimum intervals or ages are counted as valid doses. This does not apply to the
28-day minimum interval between doses of live vaccines not administered on the same day.
• It is not necessary to restart the series of any vaccine if a dose was given late or if a dose is past due. Additional doses of a vaccine
series that are administered after the due date do not affect final immunity.
• Children may be allowed to attend child care and school if they have received at least one dose of all required vaccines due for
their age or grade, and the next doses are not yet due. They must complete the remaining doses of vaccine on schedule. These
children are in the process of receiving immunizations.
Varicella
If a parent reports their child had varicella disease (chickenpox), the child is not required to receive varicella
vaccine. Record the child’s history of varicella.
The first dose of varicella must be administered on or after the child’s first birthday (or within four days
before the birthday) or they will not count toward the immunization requirement and must be repeated.
MMR & Hep A
The first doses of measles, mumps and rubella (MMR) and hepatitis A vaccines must be administered on
or after the child’s first birthday (or within four days before the birthday) or they will not count toward the
immunization requirement and must be repeated.
Hib & PCV
Hib and PCV vaccines are not required for students in preschool, pre-kindergarten or kindergarten
programs operated by schools unless the facility is a licensed child care facility. Hib and PCV vaccines are
required for children attending licensed child care facilities.
The number of doses of PCV and/or Hib may range from one to four depending on the age of the child,
when the first dose was given and type of vaccine used.
DTaP
If the fourth dose of DTaP is administered on or after the child’s fourth birthday, then the fifth dose
of DTaP is not required.
IPV
If the third dose of IPV is administered on or after the child’s fourth birthday, and at least six months
from the previous dose, then the fourth dose of IPV is not required.
Tdap
The Centers for Disease Control and Prevention (CDC) recommends a dose of Tdap on or after the 11
th
birthday even if previously received. An inadvertent dose of DTaP on or after the 11
th
birthday may be
accepted for the seventh grade Tdap requirement.
Hep B
Students ages 11 through 15 years who have not received Hep B vaccine may receive a two dose
series of Merck
®
Adult Hepatitis B vaccine to comply with this requirement. All other children
(younger or older) must receive three doses of pediatric hepatitis B vaccine.
