Health vaccines and their associated compliance listings are based on state guidelines. While Infinite Campus maintains standard guidelines for all states, districts have the ability to enter additional compliances. The following information describes vaccine compliance rules as defined by the Maryland Department of Health.

For more information on the creation, modification or deletion of vaccine compliances, see the Vaccines page.

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.
