The Centers for Disease Control and Prevention (CDC) opened state ordering for 2026–2027 COVID-19 vaccines under the Vaccines for Children program this week, according to the Department of Health and Human Services (HHS). The vaccines had been approved by the Food and Drug Administration in late August.
HHS initially told Ars Technica on Wednesday that the CDC had not yet finalized procurement decisions for the shots. The department's statement suggested Trump officials were questioning whether children should receive them, emphasizing "responsible stewardship of taxpayer resources" and ensuring that federally purchased vaccines are "appropriate for the populations those programs serve."
Public health advocates have raised concerns that the delay was politically motivated, pointing to Health Secretary Robert F. Kennedy Jr.'s long history of anti-vaccine activism. The Trump administration has provided no clear explanation for the nearly monthlong gap between FDA approval and the opening of state ordering.
