Letter to all Representatives and Senators:
The undersigned organizations, representing health care clinicians, public health professionals, scientists, patients, and family advocates, urge you to conduct swift and robust oversight regarding the abrupt changes to the U.S. childhood vaccine schedule announced on Jan. 5, 2026. It is essential that action is promptly taken to protect vaccine availability and coverage for all previously recommended immunizations for all families, including through the Vaccines for Children program.
