President Donald Trump has endorsed a study by the Department of Health and Human Services from January that suggests reducing the number of vaccines recommended for American children. An executive order issued by Trump directs federal agencies to align their policies with the study’s findings, advocating for changes previously called for by Health Secretary Robert F. Kennedy Jr. The study indicated that the United States recommends more childhood vaccines compared to many other developed countries.
Previously, the Trump administration attempted to reduce the number of recommended vaccines following this report. However, a federal judge in Massachusetts blocked the move. The administration is currently appealing the decision. The study outlines a vaccination plan against 11 diseases for all children, while recommending several others only for high-risk groups or through “shared decision-making” between doctors and patients. Vaccines affected by this recommendation include those for flu, rotavirus, hepatitis A, hepatitis B, some forms of meningitis, and RSV.
Trump’s order strengthens the study’s impact amidst an effort by the administration to shift focus from Kennedy’s controversial vaccine policies to other health topics. The Centers for Disease Control and Prevention (CDC) is directed to review the study and adjust its vaccine recommendations accordingly. The order emphasizes the need for ‘maximum flexibility’ for parents and doctors, ensuring that any changes continue to provide Americans access to necessary vaccines.
While the federal government and CDC offer vaccine guidance, individual states control vaccine requirements for school entry. Some states have started forming alliances to counter the Trump’s administration’s vaccine guidance.
Trump commissioned the study in December, adding to Kennedy’s ongoing efforts to influence national vaccine guidance with his skeptical stance. Last year, Kennedy announced that the CDC would not recommend COVID-19 vaccines for healthy children and pregnant women, a decision that faced criticism from public health experts due to the absence of supporting data. Additionally, Kennedy restructured the CDC vaccine advisory committee by replacing members with individuals who share his skepticism towards vaccines.
The report highlighted an increase in vaccine recommendations for American children in recent years, alongside examples from countries where no vaccines are mandated for school attendance.
