The revised schedule put forward by the Trump administration calls for immunizing children against 11 diseases, down from 18 currently recommended by the Centers for Disease Control and Prevention. The directive also seeks to separate the combined MMR vaccine into individual shots for each disease, though no such single-disease vaccines are currently available on the U.S. market.

“Today we’re proud to officially announce the United States of America’s gold standard childhood vaccination recommendations,” Trump said in the Oval Office before signing the order. “Effective immediately, my administration is recognizing gold standard childhood vaccine recommendations for only 11 core vaccinations against the most serious and dangerous diseases, along with the MMR, which hopefully will be split up.”

Six Vaccines Removed from Routine Schedule

The order would drop six vaccinations from the routine childhood immunization schedule: RSV, Hepatitis A, Hepatitis B, Meningococcal ACWY, Rotavirus, and Influenza. It also directs the nation’s health department to improve research on vaccines, which are already extensively studied through rigorous safety trials and ongoing tracking systems.

The move comes as Trump has shown a personal interest in vaccine policy, with his efforts thrown into high gear by his alliance with Health Secretary Robert F. Kennedy Jr., who has questioned vaccine safety for decades. During Monday’s signing, Trump repeatedly suggested vaccines could be linked to autism, despite scientific consensus based on decades of research firmly concluding there is no such connection.

“Proof of it, where they have a vaccination that looks like the size of a bottle of soda poured into a little child’s body,” Trump said. “And bad things happen in many cases, in too many cases, because this is an explosion. This is an epidemic.” The facts do not support the president’s claim.

Legal Challenges and Implementation Hurdles

Dorit Reiss, a law professor at the University of California College of the Law at San Francisco, said the latest effort will likely face similar legal challenges to past actions by the Trump administration. “The president’s familiarity with the administrative law is limited,” Reiss stated. “The problem is that this isn’t likely to hold up in court.”

It remains unclear whether vaccine makers would be able to market individual shots for measles, mumps, and rubella, a process that would likely require new Food and Drug Administration approvals. Two versions of the combined MMR vaccine are currently available for use in the U.S., but no shots for each disease individually are on the market.

Kush Desai, a spokesperson for the president, told the Associated Press the plan to develop single-disease vaccines would “give parents more options on timing and frequency for their children” and increase vaccine uptake. However, public health experts raise concerns that spacing out shots could lead to an increased risk that children become infected with a vaccine-preventable disease before returning for another visit.

Medical Community Raises Safety Concerns

Doctors say the order is based on pseudoscience and will harm children. The changes appear to be motivated by misinformation, public health experts warn, as childhood vaccines go through rigorous studies and safety tracking continues for years as the shots are used in practice.

Trump promoted his long-held but discredited theory that childhood shots should be spaced out into separate medical visits, despite decades of research showing that the current vaccination schedule is both safe and effective. Scientific consensus based on large-scale studies firmly rejects any link between vaccines and autism spectrum disorder, which Trump repeatedly suggested during the signing ceremony.

Kennedy also claimed that American children receive 72 shots under the current schedule, though this number includes vaccines administered during pregnancy and counts individual components of combined shots separately, making it a misleading representation of the actual childhood immunization count.

Political Timing Raises Questions

The executive order arrives months ahead of the midterm elections on an issue that Trump’s own pollsters have warned is unpopular with voters. Despite this internal guidance, the president has pressed forward with his vaccine agenda, which overlaps with past actions by his administration that have run into legal challenges in federal courts.

It remains unclear how the overarching directive will change current vaccination recommendations in practice, given the potential legal obstacles and the administrative procedures required to modify CDC guidelines. The order directs federal agencies to reassess the timing and sequencing of childhood vaccines, but implementation details have not been specified.

International Developments Mentioned

During the broader news briefing, the White House also addressed other matters, including that Tropical Storm Dolphin made landfall in eastern China. President Trump’s Board of Peace confirmed it remains in discussions with Israel after Prime Minister Benjamin Netanyahu rejected Trump’s Gaza peace plan in yet another public break with the White House.

“We’re talking about a true dismantling, not a fictitious dismantling,” Netanyahu said through a translator. “We’re speaking with the Americans about this subject. They have ideas. Some of them are acceptable to us, and some are unacceptable to us.”

Despite the impasse, operations continued to build a base for international peacekeepers if and when they are deployed to Gaza. Hamas stated it remains “committed to the road map for peace” despite ongoing tensions.

What Happens Next

The immediate impact of Trump’s executive order remains uncertain as legal experts predict swift challenges in federal court. The directive requires federal agencies to take action, but changing official CDC recommendations involves complex administrative procedures that cannot be accomplished through executive fiat alone.

Public health advocates warn that any reduction in childhood vaccination rates could lead to outbreaks of preventable diseases, particularly as measles cases have risen in recent years in communities with lower immunization coverage. The long-term consequences of the order will depend on whether it withstands legal scrutiny and how federal health agencies respond to the directive.
