Mississippi requires documented immunizations for every child entering school, Head Start, or daycare under Miss. Code §41-23-37. Mississippi uses Form 121 (Certificate of Immunization Compliance) as the official proof — and you can now print it online through MyIR. Here is exactly what's required, how to access your records, and what to do if anything is missing.

Mississippi follows the CDC recommended childhood immunization schedule for determining which vaccines and how many doses are required at each age. The specific dose count depends on your child's age at enrollment.
MyIR is the online portal maintained by the Mississippi State Department of Health that lets parents view immunization records and print Form 121 (Certificate of Immunization Compliance) — the document Mississippi schools require.

Use "Find My Records" and enter your child's personal information. If it matches the MSDH immunization registry, you'll see their immunization history, any outstanding doses needed, and the option to download Form 121.
If your child is up to date on immunizations, download and print Form 121 directly from MyIR. This is the certified document Mississippi schools accept for enrollment — no trip to the health department needed.
Mississippi schools require Form 121 — the Certificate of Immunization Compliance. Without it, a child cannot attend school. If your child is behind on immunizations:
Mississippi's Form 121 requirement, county health department visits, and immunization records scattered across Jackson, Gulfport, Hattiesburg, or wherever life has taken your family. Family Stork keeps your child's entire vaccination history organized in one place.
Give any clinic your child's private @families.familystork.com address. They send vaccine records and visit summaries — the health timeline builds itself. When the school asks for documentation, you open one app and hand over a complete record.

Mississippi recognizes medical exemptions and religious exemptions from school immunization requirements. Both require formal application through the Mississippi State Department of Health:
Only the Certificate of Medical/Religious Exemption (Form 122), signed by the State Epidemiologist or Deputy State Epidemiologist, constitutes official proof of exemption. Children with exemptions may be excluded from school during a disease outbreak.
Give any Mississippi clinic your child's private @familystork address. They send records; the timeline builds itself. No portal logins, no uploads, nothing for the clinic to learn.
