Which childhood vaccine schedule applies in the US in 2026?

What is pending

• 8 November 2026: HHS Task Force plans due under EO 14420 sec. 3 (90 days after 10 August). It is not yet known whether they will be published.
• Date not set: First Circuit decision in AAP v. Kennedy (No. 26-1503), argued 6 October 2026. The appeal concerns only the stay of the ACIP appointments; the government said it does not seek to disturb the stay of the January 2026 schedule.
• Date not set: Next ACIP meeting. All three 2026 meetings (March, June, October) were cancelled "due to ongoing litigation".
• Date not set: Florida's proposed change to its school-entry rule (removing hepatitis B, varicella, Hib and pneumococcal vaccines from rule-based requirements) is not final.

What applies, by question

State rules: school vaccine requirements by state · official exemption forms.

Side by side, by vaccine

The shaded column is the schedule in effect. The other columns are shown for comparison and use each body's own category names.

AAP 2026 age and dose details come partly from secondary summaries of the AAP schedule (26 January 2026). In EO 14420, hepatitis A, hepatitis B and meningococcal vaccines appear in more than one tier and the order does not say which children fall in each. The January 2026 column is shown for reference only; it is not in effect.

   HHS Secretary directive on COVID-19 vaccine for healthy children and pregnant women (background)

   Secretary Kennedy ordered CDC to stop recommending COVID-19 vaccination for pregnant women and 'healthy' children. CDC implemented it by removing the pregnancy recommendation and moving the child recommendation from routine to shared clinical decision-making (SCDM), without an ACIP vote (as described in the 16 Mar 2026 court order).

   Effect on what applies: NOT stayed by the 16 Mar 2026 order (the court found plaintiffs had not shown a justiciable claim against it). COVID-19 for healthy children 6 mo-17 y therefore remains SCDM on the currently posted CDC schedule.

   HHS Secretary removed all 17 sitting ACIP members and appointed new ones (appointments dated 11 Jun 2025, 11 Sep 2025 and 13 Jan 2026 per the court order).

   Effect on what applies: The 13 appointments made on those dates were stayed on 16 Mar 2026; ACIP has not met in 2026.

   Reconstituted ACIP votes: June 2025 (thimerosal-free flu vaccines; clesrovimab), September 2025 (COVID-19 to SCDM; MMRV not recommended under age 4), December 2025 (hepatitis B birth dose to individual-based decision-making for infants of HBsAg-negative mothers) (background)

   The court order describes three challenged votes: June 2025 thimerosal vote, September 2025 COVID-19 routine-to-SCDM vote, and December 2025 vote '8 to 3 to recommend individual-based decision-making' for the hepatitis B vaccine, including the birth dose, for infants born to women who test negative. CDC adopted these into its schedules (e.g., CDC release of 6 Oct 2025 on COVID-19 and standalone chickenpox vaccination for toddlers).

   Effect on what applies: The 16 Mar 2026 order 'STAYS all votes taken by the now-stayed ACIP'. CRS reports the status of clesrovimab (June 2025 vote, not on the January 2025 schedule) is 'unclear'. The currently posted CDC notes again show a routine hepatitis B birth dose and permit MMRV.

   Presidential Memorandum: 'Aligning United States Core Childhood Vaccine Recommendations with Best Practices from Peer, Developed Countries'

   Directed HHS/CDC to review peer-country childhood schedules and, if those practices are judged superior, update the U.S. core schedule while preserving access. Cited the U.S. recommending vaccines against 18 diseases for all children vs 10 in Denmark, 14 in Japan, 15 in Germany (per search excerpts of the memo; full text not read directly).

   Effect on what applies: None by itself; it is the stated basis for the 5 Jan 2026 CDC memo and for EO 14407 and EO 14420.

6. 2026-01-05 · CDC / HHS · Primary source

   CDC revises the childhood immunization schedule (Acting CDC Director decision memo)

   Acting CDC Director Jim O'Neill (HHS Deputy Secretary) signed a decision memo accepting an HHS scientific assessment of peer-country schedules. CDC kept three categories ('Immunizations Recommended for All Children', '...for Certain High-Risk Groups or Populations', '...Based on Shared Clinical Decision-Making'), each stated to require insurance coverage without cost-sharing. Recommended for all children: measles, mumps, rubella, polio, pertussis, tetanus, diphtheria, Hib, pneumococcal, HPV, varicella (routine immunizations reduced from 17 to 11). Per the court order: RSV, hepatitis A, hepatitis B, MenACWY, MenB and dengue limited to high-risk groups; rotavirus, COVID-19, influenza, hepatitis A, hepatitis B and meningococcal moved to SCDM. Per CRS R48982: HPV changed to one dose. Denmark: the memo states the Director relied on discussions with health officials from Japan, Germany and Denmark; the CDC release cites Denmark ('immunizes children against 10 diseases') as the low end of the comparison. Official documents describe alignment with 'peer, developed countries' (20 countries per CRS), not a copy of Denmark's schedule; 'modelled on Denmark' is media framing (the 10 'consensus' diseases do coincide with Denmark's 10, plus varicella).

   Effect on what applies: Took effect on the CDC website in January 2026; stayed on 16 Mar 2026 and no longer in effect. The government's appeal does not challenge the stay of this memo.

Northeast Public Health Collaborative, 12 Jan 2026: 'continues to recommend the American Academy of Pediatrics' (AAP)' schedule; it describes itself as a voluntary coalition and 'does not necessarily speak on behalf of every member agency or state'.

   Effect on what applies: State-level recommendations only; they do not change federal coverage rules. School-entry requirements remain set by each state's law and rules.

Released in AAP Red Book Online; endorsed by other medical organizations (secondary reports say 12, incl. AMA, AAFP, ACOG, IDSA). CRS cites a 5 Feb 2026 date (likely the Pediatrics journal publication).

   Effect on what applies: Professional-society guidance. Used as the reference schedule by many states. It does not by itself set federal insurance, VFC or school requirements.

11. 2026-03-16 · Court (U.S. District Court, D. Mass.) · Primary source

    District court stays the January 2026 schedule, 13 ACIP appointments and all votes of the reconstituted ACIP (AAP v. Kennedy, D. Mass. No. 1:25-cv-11916-BEM, ECF 291, Judge Brian E. Murphy)

    Ordering paragraphs: '(i) The Court STAYS the January 2026 Memo revising the CDC's childhood immunization schedule pursuant to 5 U.S.C. § 705. (ii) The Court STAYS the appointments of the thirteen ACIP members appointed on June 11, 2025, September 11, 2025, and January 13, 2026. (iii) The Court further STAYS all votes taken by the now-stayed ACIP.' The court held the memo was likely contrary to law (Director acted without ACIP) and arbitrary and capricious. It declined to enjoin ACIP from meeting and declined relief on the May 2025 COVID-19 directive. Reported at 823 F. Supp. 3d 141.

    Effect on what applies: CRS: the changes 'presently have no effect and the agency cannot implement them'; schedules 'largely reverted' to the January 2025 versions, except the April 2025 ACIP recommendations and the May 2025 COVID-19 change remain in effect. (Georgetown CCF described this as the June 2024-adopted schedule being back in effect; CRS R48982 also mentions 'May 2025' in one place. The order itself does not name a replacement schedule.) The claim 'reverted to January 2025 schedule' is accurate only with those two exceptions.

    Sec. 1 notes implementation of prior directives 'has been delayed due to litigation over the composition of the Advisory Committee on Immunization Practices and separate updates to the Federal vaccine schedule.' Sec. 2(a) declares 'Gold Standard Childhood Vaccine Recommendations' in three categories: (i) recommended for all children: measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Hib, pneumococcal disease, HPV, varicella; (ii) certain high-risk groups or populations: RSV monoclonal antibodies, hepatitis A, hepatitis B, meningococcal B, meningococcal ACWY, dengue; (iii) shared clinical decision-making: hepatitis A, hepatitis B, rotavirus, meningococcal disease, influenza, COVID-19. Sec. 2(b): MMR 'should be administered in three separate single-disease shots once such products are domestically available' and, 'to the maximum extent feasible, all childhood immunizations should be administered at separate medical visits.' Sec. 2(c): agencies to advance them 'to the fullest extent allowable by law.' Sec. 2(d): states 'are advised to review' and 'consider updating' school-requirement laws. Sec. 3: HHS, through the Task Force on Safer Childhood Vaccines, to present plans 'within 90 days' on single-antigen options starting with MMR (while 'guaranteeing continued availability of combination vaccines'), timing/sequencing, alternative adjuvants to aluminum, risk/benefit evaluation, and safety monitoring. Sec. 4: Attorney General to support 'meritorious legal actions' against state laws, including on religious and medical exemptions; DOJ, Education and HHS to ensure contractors and grantees, including states, comply with obligations including exemptions 'to the extent applicable under Federal law'.

    Effect on what applies: Policy declaration; it does not amend the CDC schedule, which remains subject to the court stay. The tier lists match the stayed January 2026 categories. Sec. 5(c): creates no enforceable rights. 90-day plan deadline falls on 8 Nov 2026.

Common questions

Is the new 2026 childhood vaccine schedule in effect?

No. As of 28 October 2026 the January 2026 CDC schedule is stayed by a federal court order of 16 March 2026 (AAP v. Kennedy). CDC posts and applies its 2025 schedule, with COVID-19 vaccination as shared clinical decision-making for healthy children.

What does Executive Order 14420 change?

EO 14420 (10 August 2026) directs agencies to organise childhood vaccine recommendations into three tiers (all children, high-risk groups, shared clinical decision-making), says MMR should be offered as three single-disease shots once such products are available in the US, and asks HHS for plans within 90 days (8 November 2026). It does not itself change the CDC schedule now posted.

What is shared clinical decision-making?

A CDC recommendation category in which vaccination is decided individually between a patient or parent and a clinician, rather than recommended for everyone in an age group. Vaccines in this category remain covered by most insurance and by VFC.

Do school vaccine requirements change?

Not because of the federal actions alone. School and child-care requirements are set by each state; check your state's page for its current rules and exemptions.
