Maryland school immunization requirements are governed by COMAR 10.06.04, administered by the Maryland Department of Health. The primary document for school enrollment is the Certificate of Immunization (form MCH 1140). Maryland also requires Hepatitis A vaccination for kindergarten — one of the requirements that catches families moving in from other states. Here is the complete checklist with official citations.

Maryland's official school immunization form is the Certificate of Immunization (MCH 1140), issued by the Maryland Department of Health. This certificate must be completed and signed by a licensed healthcare provider and submitted to the school before enrollment. Under COMAR 10.06.04, Maryland schools must have immunization documentation on file for every student.
Required vaccines for Maryland school enrollment (K–12):
Maryland requires two doses of Hepatitis A vaccine for kindergarten entry, a requirement that has been in place under Maryland regulations but that families moving in from states without a Hep A school mandate often encounter as a surprise.
The two Hep A doses are spaced at least 6 months apart. If your child entering kindergarten has only received one dose — or none — the second dose cannot be given until at least 6 months after the first. Check your child's immunization history as early as possible, ideally 7–8 months before the start of school.
If your child's Hep A series is incomplete, contact your pediatrician to review the record and determine next steps. Maryland schools can grant a provisional enrollment period while catch-up vaccinations are in progress — contact your school's health office for the specific policy.

Maryland maintains ImmuNet, the state's immunization information system. Healthcare providers and local health departments use ImmuNet to track and verify vaccination history. If your child has received care from Maryland providers, most of those doses should appear in ImmuNet.
To access your child's ImmuNet record:
If you are moving to Maryland from another state: out-of-state records do not transfer automatically to ImmuNet. Bring a complete, signed paper immunization history from your former provider. Your new Maryland pediatrician will enter prior documented doses into ImmuNet at the first visit.

Ask your pediatrician or local health department to pull an ImmuNet record. If your child is entering kindergarten, confirm both Hepatitis A doses are complete and dated at least 6 months apart. Any gaps will need time to address before the first day.
Maryland pediatricians are booked in July–August. Schedule the well-child visit early. Have your physician complete and sign the MCH 1140 at that visit — or confirm they will provide a signed certificate that meets COMAR 10.06.04 requirements.
Confirm both the Tdap booster and first MenACWY dose are documented before 7th grade entry. Your child's physician can review the current record at the annual visit and advise on what, if anything, needs to be scheduled.
Maryland schools require documentation before enrollment. Contact your school's health office to confirm their submission process — some districts accept digital copies; others require the original or a certified copy.
