General Compliance
- Vaccine doses administered less than or equal to 4 days before the minimum interval of age are counted as valid.
- Doses administered 5 days earlier than the minimum interval or age are not counted as valid doses and should be repeated as age appropriate.
- For compliance calculations, 4 weeks = 28 days
- Intervals of 4 or more months is calculated by calendar months.
Additional Compliance Check
In Maryland, there is a scheduled task that runs nightly. This process determines whether a student is in compliance based on MD State rules. If the student meets the MD compliance rules, the box on the enrollment is checked. Once the checkbox is checked, it remains checked unless you manually clear the checkbox.
