Health Immunization: Rules

The following Health Immunization rules are evaluated by the PowerSchool Health rules engine. The vaccination rules vary depending upon when the student first entered a California school.

Notes:

Requirements for K-12 admission also apply to transfer pupils.
Combination vaccines (e.g., MMRV) meet the requirements for individual component vaccines. Doses of DTP count towards the DTaP requirement.
Receipt of a dose up to (and including) 4 days before the birthday will satisfy the school entry immunization requirement.
For children in ungraded schools, pupils 12 years and older are subject to the seventh-grade advancement requirements.
Students with a school entry date before 7/1/2019 who are over 18 will be displayed as compliant, regardless of the number of doses for each vaccine.
Any student above 5 years of age who has a School Entry Date on or after 7/1/2019 will show as compliant, even if there are no doses for HIB.
