WASHINGTON June 1, 2026— The American College of Physicians is deeply concerned by the executive order that the administration issued on May 29, 2026, directing the U.S. Centers for Disease Control and Prevention (CDC) to alter the childhood vaccine schedule. This is the second time the administration has attempted to unilaterally substitute vaccine guidance from other countries to replace the U.S. vaccine schedule which was developed for the specific needs of the U.S. population. The U.S. childhood vaccine schedule was designed through years of transparent, scientific review focused on preventing serious illness, outbreaks, and deaths among our country’s large, diverse population with uneven access to health care services. The evidence is clear: vaccines are safe and effective at preventing deaths, hospitalizations, and the spread of disease. The changes that this executive order directs cannot be allowed to move forward.
