CDC vs AAP Vaccine Schedule 2026
How the CDC and AAP childhood immunization schedules differ in 2026, how to read either chart by age, and which one your pediatrician follows.
Published · Updated
The CDC immunization schedule 2026 and the AAP schedule are two documents: the CDC child and adolescent immunization schedule by age, carrying its "Addendum updated July 2, 2025" line when checked on September 18, 2026, and the AAP's 2026 schedules for birth through 6 and 7 through 18 years, which keep several vaccines the federal schedule dropped from routine recommendation.
Both exist. Both are current. Neither can see your child. The chart is a map, not a to-do list. A map shows where things sit relative to one another. It does not name the next turn for one particular kid, because a premature birth, a missed visit, a chronic condition or a trip abroad can each move a recommendation.
What is the CDC child and adolescent immunization schedule?
It is one table that places every routine vaccine against an age band from birth through 18 years, published for health care providers. The CDC child and adolescent immunization schedule by age carries the line "Addendum updated July 2, 2025" beside its title. Its rows include hepatitis B, rotavirus, DTaP, Hib, pneumococcal conjugate, inactivated poliovirus, COVID-19, influenza, MMR, varicella, hepatitis A, Tdap, HPV, meningococcal ACWY, meningococcal B, RSV, dengue and mpox.
Three companion documents sit beside it. Knowing which one answers which question saves an hour of scrolling.
| Document | Written for | What it answers |
|---|---|---|
| CDC schedule by age, addendum updated July 2, 2025 | Clinicians | Which vaccines the federal schedule places at a given age |
| CDC child immunization schedule notes, July 2, 2025 | Clinicians | Dosing frequencies, intervals, special situations |
| CDC catch-up schedule, addendum updated July 2, 2025 | Clinicians | How to resume a series after a delay |
| CDC Recommended Vaccines for Young Children, July 2, 2025 | Parents | The same doses, without the footnote apparatus |
| AAP 2026 schedules, birth-6 and 7-18 years | Pediatricians and parents | What the AAP recommends in 2026 |
The parent-facing CDC version, Recommended Vaccines for Young Children, shows the same doses as a plain grid and prints the same July 2, 2025 date at the top and the bottom of the page.
Read the live page rather than a copy. A screenshot from a group chat cannot be updated. A posted page can be, and the date beside the title is how you check that what you are reading is still what the agency posts today.
Why do the CDC and AAP schedules differ in 2026?
Because two bodies now publish two documents. The AAP's ask-the-pediatrician answer on schedule differences, updated January 30, 2026, states that the federal schedule removed several vaccines from routine recommendation — it names rotavirus, hepatitis A, hepatitis B, COVID-19, influenza and meningococcal disease — and that the AAP "continues to strongly recommend the full set of immunizations to keep your child healthy and will keep publishing its own evidence-based vaccine guidance." The AAP adds that its recommendations "are designed for kids who live in the U.S." and rest on U.S. data and disease patterns. Its 2026 immunization schedules are published in two parts, birth through 6 years and 7 through 18 years.
Two honest notes belong here. First, the CDC schedule page still displayed its July 2, 2025 addendum, and every row listed above, when this article was checked on September 3, 2026; federal pages and the AAP page move at different speeds, so read the date on each rather than trusting anyone's summary of both. Second, the CDC immunization schedule 2026 argument is not one this page settles. Which document your practice follows is a clinical decision made by the clinician who knows your child. "Which schedule does this practice use in 2026?" is a fair question to ask at the desk, and it has a short answer.
How do you read the schedule by age instead of by vaccine name?
Start at the top of the chart with age, not down the left side with acronyms. Find the column your child is standing in — the early months, the toddler bands, the school-age band, the adolescent band — then read down it. That column is the set of vaccines the schedule places around this age. Some bars begin earlier and continue. Some are a single window. Influenza is seasonal and sits beside the age-based rows rather than inside them.
Three habits make the age-column method work.
- Read the column, not the row. Scanning for a familiar acronym leads into the footnote forest; scanning for an age leads to a short list.
- Do not count coloured rectangles into a shopping list. Combination products mean one injection can cover several rows, so the number of diseases on the paperwork is often larger than the number of needles.
- Treat the after-visit summary as the record. The chart describes what is typical. The summary describes what your child actually received.
The first year holds the most crowded columns, which is why it gets its own walk-through in the first twelve months, visit by visit.
What do the footnotes and the catch-up schedule actually do?
The footnotes carry the exceptions. The CDC child immunization schedule notes, also dated July 2, 2025, exist to "guide health care providers in determining recommended vaccine types, dosing frequencies and intervals, and considerations for special situations." Parents mainly need to know the notes exist, so that a blank cell is not read as "we skipped you" and a filled cell is not read as "everyone, no exceptions."
The catch-up schedule is a separate table, not a punishment chart. The CDC catch-up immunization schedule for children and adolescents is organised in two blocks, 4 months through 6 years and 7 through 18 years, and gives the minimum intervals a clinician uses to resume an interrupted series. It carries the same July 2, 2025 addendum date. If a dose is late, the plan comes from that table and the clinician reading it, which is the whole point of how catch-up doses are actually scheduled.
What does the schedule not tell you?
It does not tell you which product the clinic stocks. A brand printed on an old card is a label from a past visit, not a shopping instruction, and manufacturers change what is on the shelf.
It does not tell you your state's school rule. Kindergarten and daycare lists are set by state statute and district policy, and they can be stricter or worded differently than any national chart.
It does not hold your dates. Clinics, pharmacies and travel offices each keep a slice of the history, and no federal page stores a family's record. A blank on your copy is honest; a guessed date is not. If the phrase "up to date" itself is the confusing part, what being up to date actually means unpacks it.
This page covers children and adolescents only. It does not cover recommendations for people 19 and older, and it does not cover entry requirements for international travel. And no page titled "CDC immunization schedule 2026" on a third-party site is the schedule; it is a copy of one, at whatever date it was written.
If you keep the dates on a phone, keep them somewhere you will still open in October. Vaxnext is one option for iPhone and Android: it holds a folder per family member, its reminders work offline and without an account, and the vaccine dates you type stay on the device. It is free and ad-supported — Google Play lists it as containing ads, and it shows banner and interstitial ads through AdMob — but a vaccine history is never what an ad network is shown. A paper card you can find still beats a perfect app you never open.
FAQ
Which schedule should a U.S. parent follow in 2026?
That is a question for your child's clinician, not for a website. In 2026 the CDC posts a child and adolescent schedule for providers, and the AAP publishes separate 2026 schedules for birth through 6 years and 7 through 18 years. Practices differ on which they follow, so ask yours which document it uses and confirm your child's own situation with them.
Where is the official CDC catch-up schedule?
The CDC publishes it as a separate page, "Catch-up Immunization Schedule for Children and Adolescents," at cdc.gov under vaccines/hcp/imz-schedules. It carried an addendum date of July 2, 2025 when this article was checked on September 3, 2026. It is organised as two age blocks, 4 months through 6 years and 7 through 18 years, and lists minimum intervals between doses.
Does the CDC schedule decide what my child's school requires?
No. School entry requirements in the United States are set by state law and, in places, by district policy, not by the CDC. The national schedule is a medical reference; the school list is a compliance document, and the two can differ in wording and in which doses are demanded. Your state health department and the school nurse hold the list that governs enrollment.
Not medical advice. This article is general information based on public U.S. CDC and AAP pages. It does not replace a clinician. Schedules and country entry rules change — confirm the current official page and your own situation before you act.
