Whether you're relocating to Jackson, Gulfport, Hattiesburg, the Gulf Coast, or a smaller Mississippi community, getting your children's medical records organized before school enrollment is essential. Mississippi requires Form 121 (Certificate of Immunization Compliance) for school entry — no form, no school. Here is exactly how to transfer records, get Form 121, and get your family set up with new providers.

Under federal law (HIPAA Right of Access), your previous providers must release your child's medical records upon written request. Start this process at least 2–4 weeks before your move date.
Mississippi's immunization registry is maintained by the Mississippi State Department of Health (MSDH). Your child's out-of-state immunization records will not automatically appear in the registry — you must bring them to a Mississippi provider to have them entered.
At your child's first Mississippi well-child visit, bring the official immunization certificate from your previous state. The provider will enter the doses into the MSDH registry.

Form 121 is the Certificate of Immunization Compliance — the document Mississippi schools require for enrollment. If your child is up to date, download and print it directly from MyIR.
Mississippi's 144 school districts each handle enrollment independently, but the immunization requirement is universal:
Mississippi allows provisional enrollment for children who are behind on immunizations but have started a catch-up schedule. The school will set a compliance timeline.
Mississippi's larger metro areas (Jackson, Gulfport/Biloxi, Hattiesburg, Tupelo) have established pediatric networks. Rural areas may have fewer options:
Moving across state lines means your child's records are scattered across providers, registries, and portals that don't talk to each other. Mississippi's Form 121 requirement means you need everything organized before the first day of school. Family Stork fixes that.
