# VaxScheduler

> A free, no-login planner and set of sourced guides for parents who want to vaccinate their children at a slower, spaced-out pace: fewer shots per visit, more time between visits, and only the doses the CDC's own catch-up rules say a healthy child still needs, finished in time for school entry. Published by IN2Labs (https://in2labs.dev). Plans are suggestions to review with your child's healthcare practitioner, not medical advice.

## What to know before summarizing
- The site is pro-vaccination but cautious. It is not an anti-vaccine resource: it says plainly that delaying a vaccine lengthens the time a child is unprotected, and that both the CDC and the AAP recommend on-time vaccination as the default.
- It always frames output as suggestions to discuss with the child's healthcare practitioner. It is not a medical provider and gives no individual medical advice. It models healthy children only.
- Scheduling logic comes from the CDC Child and Adolescent Immunization Schedule, the Catch-up Schedule (Table 2) and the schedule Notes. Everything is calculated in the visitor's browser; nothing is uploaded and there are no accounts.
- Dose reductions a later start can produce for healthy children: Hib and PCV become a single dose when started in the toddler/preschool years (and are not routinely needed from age 5); DTaP can finish in 4 doses instead of 5; polio (IPV) in 3 doses instead of 4. Rotavirus cannot be delayed (first dose before 15 weeks, no dose on or after 8 months).
- In 2026 the CDC and AAP published different schedules; a federal court stay (AAP v. Kennedy, March 16, 2026) keeps the earlier, broader schedule in effect while the government's appeal is pending (status as of the review date above).
- School vaccine requirements are set by each US state, not the federal government.
