Health Immunization: Rules
On this page:
Introduction
The PowerSchool Health rules engine evaluates the following Health Immunization rules to comply with the state's guidelines. The vaccination rules vary depending upon when the student first entered a school.
- A month is calculated as four weeks with seven days each (4*7 = 28 days)
- A four-day grace period is considered with each minimum age and time interval
For example, if the time interval between two doses is four weeks or one month, the actual interval is 24 days: [28 days (one month) with 4-day grace period = 24 days)]
