Frequently Asked Questions

The Vaccine Schedule & Exemption Navigator is a jurisdiction-level vaccination information hub. It organizes existing VaccineDataNavigator.org vaccine evidence pages around practical parent concerns: what vaccines are on your jurisdiction's schedule, what's required for school or daycare entry, what exemptions are available, and where to find official forms and resources. Every vaccine name links directly to the full VaccineDataNavigator evidence page — including clinical trials, VAERS data, pharmacovigilance, ingredients, and references.

No. The Vaccine Schedule & Exemption Navigator and VaccineDataNavigator provide information, not recommendations. We present publicly available data from official health authorities; we do not tell you what decision to make. Always discuss vaccination decisions with your healthcare provider.

All jurisdiction data is compiled from official health department websites, state/provincial statutes, and published immunization schedules as of mid-2026. Each jurisdiction page includes links to the official source. Data is manually curated and updated periodically — changes in law or policy may not be reflected immediately. Always verify critical information against your local health authority.

While the CDC/ACIP provides a recommended schedule, each state independently determines which vaccines are required for school entry — and at what ages. Some states require Hepatitis A for school; others don't. Meningococcal vaccine requirements vary for college. Age cutoffs and dose counts for kindergarten entry also differ from state to state. Use our Compare tool to see side-by-side differences.

Under Canada's constitution, healthcare delivery (including immunization programs) is the responsibility of each province and territory. NACI (the National Advisory Committee on Immunization) provides recommendations, but each province independently decides what to fund and what to require. This means Ontario's schedule differs from British Columbia's, which differs from Quebec's. Each province/territory page in the Vaccine Schedule & Exemption Navigator tracks the specific schedule for that jurisdiction.

• Medical exemption: For documented medical contraindications. Requires a physician's (MD/DO) statement. Available in all jurisdictions.
• Religious exemption: For sincere religious beliefs that conflict with immunization. Requirements vary — some states require notarized affidavits; some Canadian provinces require a vaccine education session.
• Personal belief exemption: For philosophical or conscientious objections unrelated to religion. Available in fewer than half of US states. Not available in any Canadian province.

Yes — and significantly so. Daycare/preschool requirements are often age-based rather than school-entry based. They frequently include vaccines not required for K–12 entry (like Hib and PCV). Each jurisdiction page includes separate daycare requirement details.

This varies widely. Some states (like Texas) treat homeschools as private schools with different reporting obligations. Other states require homeschool students to meet the same requirements as public school students. Yet others exempt homeschool students entirely. Each jurisdiction page in the Vaccine Schedule & Exemption Navigator includes a detailed homeschool section.

Start on the Vaccine Schedule & Exemption Navigator homepage and select your country — United States or Canada. You'll see a complete alphabetical list of all jurisdictions. Or use the search bar to type your state or province name directly. For a guided experience, try the Getting Started wizard.

Yes — use the Compare tool to see side-by-side comparisons of any two states, provinces, or even cross-border comparisons (e.g., Texas vs Ontario). The comparison covers schedules, exemptions, required vaccines, school and daycare requirements, and official resources.

Every vaccine referenced in a jurisdiction schedule is linked to its full VaccineDataNavigator evidence page. These pages contain: basic vaccine information, pre-licensure clinical trial data, post-licensure safety data, documented adverse events (with evidence strength ratings), disease prevention benefits, evidence summaries, key references, international surveillance data, and curated adverse event literature. The Vaccine Schedule & Exemption Navigator does not duplicate this content — it links to the canonical source.
