US Childhood Vaccine Schedule Overhauled, Aligning with Denmark’s Approach

The Centers for Disease Control and Prevention (CDC) has significantly altered the recommended childhood vaccine schedule, reducing the number of routine vaccinations from 17 to 11. This change, implemented in January 2026, aligns the US more closely with the vaccination recommendations of Denmark, a country with a smaller population and universal healthcare access.

Shift in Vaccination Policy

The overhaul represents an unprecedented change in US vaccination policy, driven by Health and Human Services Secretary Robert F. Kennedy Jr. The revised schedule now recommends vaccines for 11 diseases, compared to the previous 18. This decision comes after a memorandum from President Trump directed Kennedy and the acting director of the CDC to evaluate and adopt best practices from peer nations, specifically mentioning Denmark [NPR].

Restoring Public Trust

Senior Health and Human Services Department officials have stated that the changes are intended to restore public trust in public health initiatives, which was eroded during the COVID-19 pandemic. The pandemic led to decreased adherence to the CDC’s childhood immunization schedule, with lower rates of vaccination for diseases like measles, rubella, pertussis, and polio [NBC News].

Concerns and Criticism

The revised schedule has drawn criticism from medical and public health experts, who express concerns about the potential impact on disease prevention. Dr. Yvonne Maldonado, a professor of global health and infectious diseases at Stanford University, noted a lack of transparency surrounding the changes, stating there was “an incredible lack of transparency” and “no data” cited to support the new schedule [NBC News]. Dr. Jake Scott, an infectious diseases specialist at Stanford Medicine, described the change as “the most significant weakening of childhood vaccine recommendations” in modern American history [NBC News].

Political Considerations

Despite the changes, some anti-vaccine activists believe the revised schedule does not go far enough, advocating for the complete elimination of all vaccines. Polling data indicates that broad support for vaccines remains among voters, and politicians supporting the elimination of vaccine recommendations may face political repercussions [POLITICO].

Funding of Vaccine Research

Recent reports have highlighted a $1.6 million grant from the Department of Health and Human Services to support research by Danish vaccine researchers Peter Aaby and Christine Stabell Benn, whose work has been embraced by vaccine opponents. This funding occurred shortly after a critical analysis of their research practices was published, raising questions about the objectivity and scientific rigor of the funded study [Rolling Stone].
