Three senators are asking federal health officials to explain why states could not order updated COVID-19 vaccines through the Vaccines for Children program until nearly four weeks after federal approval. In a Sept. 29 letter, Senate Democratic Leader Chuck Schumer of New York, Sen. Edward Markey of Massachusetts and Sen. Bernie Sanders of Vermont requested a written response by Oct. 9.
The lawmakers said the Centers for Disease Control and Prevention told states and local partners on Sept. 23 that the ordering portal was open. They asked the CDC and Department of Health and Human Services to account for the delay and confirm that distribution will continue without another interruption.
What the delay affected
The Food and Drug Administration approved the updated 2026-27 vaccines on Aug. 27, the senators wrote. Families with commercial insurance could obtain doses through retail channels while the federally funded children's program was not yet accepting state orders, according to their letter. The letter does not establish how many children in New York sought a dose during that interval or when individual providers received supply.
The CDC describes the Vaccines for Children program as a source of recommended vaccines for eligible children who are uninsured, underinsured, enrolled in Medicaid, or American Indian or Alaska Native. The senators said roughly half of U.S. children receive recommended immunizations through the program, making delays consequential for families with fewer other options.
The lawmakers asked why ordering opened almost four weeks after approval and requested a comparison with schedules from the previous three years. They also asked whether political appointees at CDC or HHS intervened in procurement or ordering and sought any relevant internal communications.
Their final question concerns how and when the CDC told state health departments and immunization managers about the delay and its resolution. The letter asks for answers, but it does not establish that a political official caused the delay or that future shipments have been interrupted.
Questions about access and guidance
Schumer, Markey and Sanders said they were concerned the delay had created unequal access between children served by the federal program and those with commercial coverage. Their letter also criticizes broader federal vaccine policy, but those assertions are the senators' position, not findings from a completed investigation into the ordering delay.
The CDC's current clinical guidance distinguishes among children by age, immune status and clinical circumstances. It recommends a 2026-27 COVID-19 vaccine for children ages 6 months through 17 years with moderate to severe immunocompromise. For other children in that age range, the CDC describes shared clinical decision-making between families and health professionals.
Opening a state ordering portal does not by itself verify that every local clinic has doses on hand. Families seeking a vaccine through the children's program should check availability and eligibility with their health provider or local health department rather than assume a particular office has received supply.
The lawmakers addressed the letter to CDC Director Erica Schwartz and HHS Secretary Robert F. Kennedy Jr. The agencies' explanation and any requested records were not included with the senators' announcement.
