The Centers for Disease Control and Prevention has significantly revised its recommended childhood immunization schedule for 2026, reducing the number of vaccines universally recommended for all children from 17 to 11, a shift that moves several immunizations into risk-based or parent-directed decision categories and marks a major change in national vaccine policy.
The updated schedule, approved in December 2025 by the CDC’s Advisory Committee on Immunization Practices (ACIP), took effect January 1, 2026, and has been published on the agency’s website. CDC officials said the revisions follow a directive from the Trump administration to align U.S. vaccination policy more closely with peer nations, such as Denmark, that administer fewer routine childhood vaccines while reporting comparable health outcomes.
According to the CDC, vaccines that are no longer universally recommended for all children include those for rotavirus, meningococcal disease, hepatitis A, hepatitis B, COVID-19, and influenza. Under the revised guidance, these vaccines are now recommended only for children in specific circumstances, higher-risk categories, or based on parental discretion in consultation with healthcare providers.
One of the most consequential changes involves hepatitis B. On December 5, 2025, ACIP voted 8–3 to recommend the birth dose only for infants born to mothers who test positive for hepatitis B or whose infection status is unknown. For infants born to mothers who test negative, the guidance advises parents to consult with physicians about potential risks, including household exposure.
Similarly, Covid-19 and influenza vaccines are now recommended only for children considered at higher risk, such as those with underlying medical conditions. Vaccines for hepatitis A and B, rotavirus, and meningococcal disease are limited to defined scenarios rather than routine administration to all children.
The revised schedule continues to universally recommend vaccines for measles, mumps, rubella, polio, diphtheria, tetanus, pertussis, Haemophilus influenzae type b, pneumococcal disease, and varicella, which the CDC described as the core childhood immunization framework.
CDC officials, including Acting Director Jim O’Neill, characterized the changes as a move toward personalized, evidence-based healthcare that emphasizes informed consent and individual risk assessment rather than blanket mandates. O’Neill said proponents believe the revised schedule reduces the risk of over-vaccination while maintaining protection against the most serious childhood diseases.
The policy shift stems from a broader review initiated under Health and Human Services Secretary Robert F. Kennedy Jr., who appointed ACIP members skeptical of broad vaccine mandates. The review was also guided by a presidential order directing federal agencies to benchmark U.S. vaccine policy against countries with lower routine vaccination rates but similar public-health outcomes.
Critics have sharply opposed the changes. The American Academy of Pediatrics warned that reducing universal vaccination could lead to increased outbreaks of preventable diseases. The organization cited historical data showing that universal hepatitis B vaccination reduced infections by 99 percent and prevented thousands of cases annually. The AAP has said it will continue recommending the previous, more expansive immunization schedule in clinical practice.
Public-health experts have also raised concerns about potential gaps in herd immunity, particularly for diseases such as rotavirus and meningococcal infections, which can lead to higher hospitalization rates. Some experts estimate that reduced uptake could result in thousands of additional cases each year, with disproportionate impacts on underserved and low-income communities.
Insurance coverage is not expected to change immediately. Under the Affordable Care Act, insurers are required to cover preventive services recommended by ACIP at no cost to patients. However, health-policy analysts cautioned that the revised guidance could create confusion among parents and providers, potentially leading to lower vaccination compliance even when coverage remains available.
States will continue to control school entry vaccination requirements, and many are expected to maintain stricter mandates than the federal schedule. The impact of the changes may therefore vary widely across the country.
The CDC has said it plans outreach campaigns to help families and providers understand the new risk-based framework and individual assessment process. Nevertheless, public-health advocates warn that reduced routine vaccination could reverse decades of progress in child health.
Congressional oversight is expected, with bipartisan calls for hearings to examine the scientific basis for the revisions and their potential consequences. While no immediate data on vaccination uptake is available, federal officials said monitoring will begin with the 2026 reporting cycle, as the effects of the new schedule begin to emerge.
