Making sense of Trump's executive order on US vaccinations

On Monday, August 10, 2026, President Donald Trump signed an executive order aimed at streamlining childhood vaccine recommendations in the United States. The order reduces the current list of 18 recommended vaccines for children to 11, aligning it closely with the World Health Organization (WHO) recommendations. The WHO suggests that all children should receive vaccinations against 12 of the 30 infectious diseases listed.

Rich nations typically exceed the WHO's base level of 12 vaccinations, but not all countries do. Germany, for instance, currently recommends 14 vaccines for children in their first two years of life, including the BCG vaccine for tuberculosis and the Respiratory Syncytial Virus (RSV) vaccine, which is not on the WHO's list.

Trump's executive order proposes three distinct categories for vaccinations. The first category comprises immunizations that would be mandatory for all children, including measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type b (meningitis), pneumococcal disease, human papillomavirus, and varicella (chickenpox).

This category removes vaccines for hepatitis B, rotavirus, influenza, and RSV, which were previously part of the recommended list. Despite these illnesses potentially affecting newborns, they are not included in the new baseline category. The second category would encompass immunizations for high-risk groups or populations, such as respiratory syncytial virus monoclonal antibodies, hepatitis A, hepatitis B, meningococcal B, meningococcal ACWY, and dengue.

The third category would include vaccines to be administered based on shared clinical decision-making between doctors and patients or parents and their children. This would cover vaccines against hepatitis A, hepatitis B, rotavirus, meningococcal disease, influenza, and COVID-19.

Critics argue that Trump's executive order lacks a scientific basis and reflects the administration's previous stance on vaccination safety. Robert F. Kennedy Jr., a prominent critic, has long suggested that vaccines, including the combined MMR vaccine for measles, mumps, and rubella, cause autism. However, the US Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) maintain that there is no scientific evidence supporting this claim.

In July 2026, DW reported that a growing aversion to vaccination in the US led to a resurgence in measles infections, a disease that had previously been controlled. Similarly, Germany has witnessed a rise in measles cases, attributed largely to anti-vaccination rhetoric that emerged during the COVID-19 pandemic. Despite these concerns, the AAP's Andrew Racine stated that the executive order is not grounded in "gold-standard science," emphasizing the absence of new evidence to justify significant alterations to childhood immunization guidelines.
