WHO Defends Childhood Immunization Guidelines After Trump Order
The World Health Organization reaffirmed its science-based vaccine recommendations following the US president's decision to reduce the recommended childhood vaccine schedule from 17 to 11.
The World Health Organization (WHO) responded to a US executive order that aims to reduce the number of recommended vaccines for children on Tuesday.
The US administration decided to decrease the number of recommended childhood vaccines in the country, part of a broader push by President Trump.
On Monday, President Trump signed an executive order reinforcing the administration's effort to reduce the recommended childhood vaccine schedule from 17 to 11.
In response, a WHO spokesperson said in Geneva that WHO recommendations are based on more than 60 years of research.
The spokesperson also expressed hope that all countries would base their vaccination strategies on scientific foundations.
Updates
The executive order now specifies that childhood vaccines should be reduced from 17 to 11 diseases, mandates separation of the MMR vaccine into individual shots once available, and requires immunizations to be administered at separate visits — a shift from the CDC’s combined-schedule recommendations; additionally, it reclassifies Covid-19, influenza, and hepatitis B vaccines as subject to shared clinical decision-making, while directing the DOJ to investigate state vaccine exemptions — all of which contradict the CDC’s authority and are condemned by medical groups as scientifically unfounded and dangerous.
The executive order now explicitly recommends splitting the MMR vaccine into three separate shots once available domestically, and mandates that all childhood immunizations be administered at separate visits — a shift from the previous consolidated schedule — while the CDC’s original 17-disease recommendation remains unchanged; additionally, the order reclassifies Covid-19, influenza, and hepatitis B vaccines as subject to shared clinical decision-making, and directs the Justice Department to investigate state-level vaccine exemption violations, despite no approved monovalent vaccines currently existing in the U.S. and major medical bodies like the AAP, Merck, and GSK affirming no safety or效
The executive order now explicitly recommends splitting the combined MMR vaccine into three separate shots once available domestically, and mandates that all childhood immunizations be administered at separate visits — positions contradicted by CDC guidelines and confirmed by Merck, GSK, and AAP experts who state there is no scientific evidence supporting improved safety or efficacy from separation; additionally, the order reclassifies Covid-19, influenza, and hepatitis B vaccines as shared clinical decision-making items and directs the Justice Department to investigate state vaccine exemption enforcement, while Senator Bill Cassidy and the AAP reaffirmed the order’s danger and lack of basis
The executive order now explicitly recommends splitting the combined MMR vaccine into three separate shots once available, and mandates that all childhood immunizations be administered at distinct visits — a change from the prior 17-disease schedule that did not specify administration timing; this contradicts CDC guidelines and is unsupported by scientific evidence, as Merck, GSK, and AAP confirm no safety or efficacy benefit exists, while experts warn it will delay protection during the U.S.'s worst measles outbreak in 35 years, with 2,318 cases reported in 2026 alone.
The executive order now explicitly recommends splitting the MMR vaccine into three separate shots once available, and mandates that all childhood immunizations be administered at separate visits — a direct departure from the CDC’s combined-schedule approach — while also reclassifying Covid-19, influenza, and hepatitis B vaccines as subject to shared clinical decision-making, despite no scientific evidence supporting the safety or efficacy of separating MMR and with health experts warning this could worsen the U.S.’s worst measles outbreak in 35 years, which has seen 2,318 cases in 2026 alone.
The executive order now explicitly recommends splitting the MMR vaccine into three separate shots once available domestically, and mandates that all childhood immunizations be administered at separate visits — positions contradicted by the CDC, Merck, GSK, and the American Academy of Pediatrics, which confirm no scientific evidence supports this change and that no monovalent vaccines for measles, mumps, or rubella currently exist in the U.S.; meanwhile, Senator Bill Cassidy and the AAP have condemned the order as dangerous and unscientific, while the WHO warned that such unverified modifications significantly increase infection risks for children and communities.
