Connecticut has some of the strictest immunization requirements in the country — and only accepts medical exemptions. If you're moving from a state with broader exemptions or different vaccine requirements, your children's records will need attention before school enrollment. This guide covers what to bring, what to update, and what gaps to watch for.

Before leaving your current state, request copies of your children's medical records from every provider — pediatrician, specialists, allergist, dentist. Under HIPAA, you have the right to copies of your medical records (providers may charge a reasonable fee for copies).
What to request:
Once you establish care with a Connecticut pediatrician, bring your child's out-of-state immunization records to the first visit. Your new provider will enter the doses into CT WiZ, Connecticut's statewide immunization information system. Schools use CT WiZ to verify compliance — if your child's records aren't in CT WiZ, the school may flag them as non-compliant even though the vaccines were given.
If you're moving from a state that offers religious or philosophical vaccine exemptions, be aware: Connecticut does not accept them. Since April 28, 2021 (Public Act 21-6), only medical exemptions — signed by a physician documenting a specific medical contraindication — are accepted for school and childcare enrollment.
This means every required vaccine must be documented or a physician-certified medical exemption must be on file before your child can attend school. If your child was previously enrolled under a religious or philosophical exemption in another state, you'll need to either complete the required vaccines or obtain a Connecticut medical exemption from a Connecticut-licensed physician.
Start looking for a pediatrician before your move date, especially if you're arriving in late summer when appointment slots fill fast. Connecticut has a strong pediatric network across the state — Fairfield County, Greater Hartford, and the New Haven area all have dense provider coverage.
What to do at the first visit:
Connecticut school enrollment requires:
Submit everything to the school health office before the first day. Students without complete documentation may be excluded from attendance until records are provided.
Moving states with kids means rebuilding the records puzzle from scratch — new provider, new registry, new school forms. Family Stork makes it seamless: your child's @families.familystork.com address doesn't change when your mailing address does.
Give your new Connecticut pediatrician the same @families.familystork.com address your old provider used. They send records — the timeline keeps building. The complete history travels with the child, not with the state.
