Build a plan

Free · No sign-up · Based on the CDC & AAP schedules

Space out your child's vaccines, from birth to age 18.

For parents who do want to vaccinate but prefer to go slower: fewer shots per visit, more time between them, and only the doses the CDC's own catch-up rules say a healthy child still needs. Build a plan in a minute, then review it with your child's healthcare practitioner.

Build my plan How delayed schedules work
  • Built from CDC and FDA sources
  • Finishes by the date you choose, or tells you it can't
  • Nothing you enter leaves your device unless you turn on sync

How it works

  1. 1

    Enter the basics

    Your child's birth date and the date you want to be finished by. School entry is suggested for you, or age 18 for an older child.

  2. 2

    Set your pace

    Choose shots per visit, how visits are spaced and which vaccines to include. Doses already given are respected.

  3. 3

    Print and review

    Get a one-page plan, a calendar file or a share link to go over with your child's healthcare practitioner.

Catching up

How the CDC catch-up rules work for a child who starts late, and which doses age out.

One vaccine at a time

What one shot per visit means for visit count, time unprotected and rotavirus limits.

Your state's school rules

What each state requires for kindergarten and for middle and high school, with exemption rules and official links.

Why parents use it

Fewer shots per visit

You set the pace: how many vaccines at once and whether visits follow the usual pediatric schedule or a fixed gap.

Only the minimum still needed

Under the CDC catch-up rules, starting later can mean fewer Hib, PCV, DTaP and polio doses for a healthy child.

Done by your date

Pick a finish date and every recommended dose is placed by then, or the planner tells you when it cannot.

Why you can trust it

This is a planning aid, not medical advice. Here is how we keep it honest.

Official sources only

Every dose, minimum age and interval comes from the CDC schedule and catch-up rules, with the AAP schedule as an option. See the editorial policy.

Private by design

No accounts. The plan is built in your browser and nothing you enter is uploaded unless you opt in to an encrypted synced copy. Read the privacy policy.

Transparent changes

Every update to schedule data and guides is logged in what's changed. Published by IN2Labs.

Common questions

Is it safe to delay or space out vaccines?

It is not risk-free: the main trade-off is that your child is unprotected for longer. Both the CDC and the AAP recommend on-time vaccination as the default. A slower pace is a choice some families make with their child's healthcare practitioner.

Which vaccine cannot be delayed at all?

Rotavirus. The first dose must be given before 15 weeks of age and no dose may be given at or after 8 months.

Do we have to restart a series if we waited too long?

No. A core CDC catch-up rule is that a series is never restarted, no matter how much time has passed. Doses already given count.

The short version

At a glance

  • The VaxScheduler is a free planner that builds a spaced-out, minimum-dose childhood vaccine schedule from the CDC schedule and its catch-up rules.
  • You choose shots per visit, visit spacing and a finish date; the plan is built to complete every recommended series by your finish date (school entry by default, or age 18 for an older child), and it tells you when it cannot.
  • For healthy children, starting later can reduce doses of Hib, PCV, DTaP and polio, while rotavirus cannot be delayed at all.
  • By default everything stays on your device: there are no accounts and nothing you enter is uploaded unless you opt in to an encrypted synced copy.
