The basic structure has been in place since 1995, when federal health officials and medical organizations <a href=\"https:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/00039897.htm\">first issued a unified national standard<\/a>, though new vaccines have been added regularly as science advanced.<\/p>\n<p>That schedule is now being dismantled.<\/p>\n<p>In all, the sweeping change <a href=\"https:\/\/www.cidrap.umn.edu\/childhood-vaccines\/hhs-announces-unprecedented-overhaul-us-childhood-vaccine-schedule#:%7E:text=Federal%20officials%20today%20announced%20an,director%2C%20Jim%20O'Neill.\">reduces the universally recommended childhood vaccines from 17 to 11<\/a>. It moves vaccines against rotavirus, influenza, hepatitis A, hepatitis B and meningococcal disease from routine recommendations to \u201cshared clinical decision-making,\u201d a category that shifts responsibility for initiating vaccination from the health care system to individual families.<\/p>\n<p>Health and Human Services Secretary Robert F. Kennedy Jr., who has <a href=\"https:\/\/www.nytimes.com\/2025\/12\/04\/us\/politics\/rfk-vaccines-hhs-trump.html\">cast doubt on vaccine safety for decades<\/a>, <a href=\"https:\/\/www.hhs.gov\/sites\/default\/files\/assessment-of-the-us-childhood-and-adolescent-immunization-schedule-compared-to-other-countries.pdf\">justified these changes by citing a 33-page assessment<\/a> comparing <a href=\"https:\/\/www.theatlantic.com\/health\/archive\/2025\/07\/hhs-vaccine-policy-europe-denmark\/683640\/\">the U.S. schedule to Denmark\u2019s<\/a>.<\/p>\n<p>But the two countries differ in important ways. Denmark has 6 million people, universal health care and a national registry <a href=\"https:\/\/www.vaccinestoday.eu\/stories\/how-the-danish-vaccination-registry-became-a-cornerstone-of-denmarks-immunisation-service\/\">that tracks every patient<\/a>. In contrast, the U.S. has 330 million people, 27 million uninsured and a system where millions move between providers.<\/p>\n<p>These changes follow the CDC\u2019s <a href=\"https:\/\/www.washingtonpost.com\/health\/2025\/12\/16\/hepatitis-b-vaccine-birth-cdc-recommendation\/\">decision in December 2025 to drop a long-held recommendation<\/a> that all newborns be vaccinated against hepatitis B, despite no new evidence that questions the vaccine\u2019s long-standing safety record.<\/p>\n<figure><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/uZx_GsBVw2s?wmode=transparent&amp;start=0\" width=\"440\" height=\"260\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><figcaption><span class=\"caption\">The CDC announced an overhaul to the childhood vaccine schedule, bypassing the established process for making vaccine recommendations.<\/span><\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>I\u2019m an <a href=\"https:\/\/med.stanford.edu\/profiles\/jake-scott\">infectious disease physician<\/a> who treats vaccine-preventable diseases and <a href=\"https:\/\/scholar.google.com\/citations?user=UFGFuVgAAAAJ&amp;hl=en\">reviews the clinical trial evidence<\/a> behind immunization recommendations. The vaccine schedule wasn\u2019t designed in a single stroke. It was <a href=\"https:\/\/theconversation.com\/rfk-jr-wants-to-scrutinize-the-vaccine-schedule-but-its-safety-record-is-already-decades-long-271408\">built gradually over decades<\/a>, shaped by disease outbreaks, technological breakthroughs and hard-won lessons about reducing childhood illness and death.<\/p>\n<h2>The early years<\/h2>\n<p>For the first half of the 20th century, most states required that students be <a href=\"https:\/\/www.sciencehistory.org\/stories\/magazine\/smallpox-and-the-long-road-to-eradication\/\">vaccinated against smallpox<\/a> to enter the public school system. But there was no unified national schedule. The combination vaccine against <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK545173\/\">diphtheria, tetanus and pertussis<\/a>, known as the DTP vaccine, emerged in 1948, and the <a href=\"https:\/\/www.eisenhowerlibrary.gov\/research\/online-documents\/jonas-salk-and-polio-vaccine\">Salk polio vaccine arrived in 1955<\/a>, but recommendations for when and how to give them varied by state, by physician and even by neighborhood.<\/p>\n<p>The federal government stepped in after tragedy struck. In 1955, a <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC1570077\/\">manufacturing failure at Cutter Laboratories<\/a> in Berkeley, California, produced batches of polio vaccine containing live virus, causing paralysis in dozens of children. The incident made clear that vaccination couldn\u2019t remain a patchwork affair. It required federal oversight.<\/p>\n<p>In 1964, the U.S. surgeon general <a href=\"https:\/\/www.congress.gov\/crs-product\/IF12317\">established the Advisory Committee on Immunization Practices, or ACIP<\/a>, to provide expert guidance and recommendations to the CDC on vaccine use. For the first time, a single body would evaluate the evidence and issue national recommendations.<\/p>\n<figure class=\"align-right zoomable\"><a href=\"https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip\" sizes=\"auto, (min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\" srcset=\"https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=771&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=771&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=771&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=969&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=969&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/710989\/original\/file-20260106-56-u9thn7.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=969&amp;fit=crop&amp;dpr=3 2262w\" alt=\"A drawing of a boy on crutches watching children play\" width=\"426\" height=\"547\" \/><\/a><figcaption><span class=\"caption\">This editorial cartoon commenting on the polio vaccine won the Pulitzer Prize in 1956.<\/span> <span class=\"attribution\"><a class=\"source\" href=\"https:\/\/commons.wikimedia.org\/wiki\/File:Wonder_Why_My_Parents_Didn%27t_Give_Me_Salk_Shots%3F.jpg\">Tom Little via Wikimedia Commons<\/a><\/span><\/figcaption><\/figure>\n<h2>New viral vaccines<\/h2>\n<p>Through the 1960s, vaccines against measles (1963), mumps (1967) and rubella (1969) were licensed and eventually <a href=\"https:\/\/doi.org\/10.2105\/AJPH.2012.301075\">combined into what\u2019s known as the MMR shot in 1971<\/a>. Each addition followed a similar pattern: a disease that killed or disabled thousands of children annually, a vaccine that proved safe and effective in trials, and a recommendation that transformed a seemingly inevitable childhood illness into something preventable.<\/p>\n<p>The rubella vaccine went beyond protecting the children who received it. Rubella, also called German measles, is mild in children but <a href=\"https:\/\/doi.org\/10.1093\/pch\/12.9.798\">devastating to fetuses<\/a>, causing deafness, heart defects and intellectual disabilities when pregnant women are infected.<\/p>\n<p><a href=\"https:\/\/doi.org\/10.1126\/science.abb8290\">A rubella epidemic in 1964 and 1965<\/a> drove this point home: 12.5 million infections and 20,000 cases of congenital rubella syndrome left thousands of children deaf or blind. Vaccinating children also helped protect pregnant women by curbing the spread of infection. By 2015, <a href=\"https:\/\/www.paho.org\/en\/news\/29-4-2015-americas-region-declared-worlds-first-eliminate-rubella\">rubella had been eliminated<\/a> from the Americas.<\/p>\n<h2>Hepatitis B and the safety net<\/h2>\n<p>In 1991, the CDC added <a href=\"https:\/\/theconversation.com\/hepatitis-b-shot-for-newborns-has-nearly-eliminated-childhood-infections-with-this-virus-in-the-us-265560\">hepatitis B vaccination at birth<\/a> to the schedule. Before then, around <a href=\"https:\/\/doi.org\/10.1542\/peds.108.5.1123\">18,000 children every year contracted the virus before their 10th birthday<\/a>.<\/p>\n<p>Many parents wonder why newborns need this vaccine. The answer lies in biology and the limitations of screening.<\/p>\n<p>An adult who contracts hepatitis B has a 95% chance of clearing the virus. An infant infected in the first months of life has a <a href=\"https:\/\/doi.org\/10.1098\/rspb.1993.0102\">90% chance of developing chronic infection<\/a>, and <a href=\"https:\/\/doi.org\/10.1053\/j.gastro.2011.12.061\">1 in 4 will eventually die<\/a> from liver failure or cancer. <a href=\"https:\/\/www.hepb.org\/what-is-hepatitis-b\/the-abcs-of-viral-hepatitis\/\">Infants can acquire the virus<\/a> from their mothers during birth, from infected household members or through casual contact in child care settings. The virus survives on surfaces for days and is highly contagious.<\/p>\n<p>Early strategies that targeted only high-risk groups failed because screening missed too many infected mothers. Even today, roughly 12% to 18% of pregnant women in the U.S. are never screened for hepatitis B. Until ACIP <a href=\"https:\/\/theconversation.com\/vaccine-committee-votes-to-scrap-universal-hepatitis-b-shots-for-newborns-despite-outcry-from-childrens-health-experts-271202\">dropped the recommendation in early December 2025<\/a>, a first dose of this vaccine at birth served as a safety net, protecting all infants regardless of whether their mothers\u2019 infection status was accurately known.<\/p>\n<p>This safety net worked: <a href=\"https:\/\/www.cidrap.umn.edu\/sites\/default\/files\/searchable-download\/Universal%20Hepatitis%20B%20Vaccination%20at%20Birth%202Dec2025.pdf\">Hepatitis B infections in American children fell by 99%<\/a>.<\/p>\n<h2>A unified standard<\/h2>\n<p>For decades, different medical organizations issued their own, sometimes conflicting, recommendations. In 1995, ACIP, the American Academy of Pediatrics and the American Academy of Family Physicians jointly released the <a href=\"https:\/\/www.cdc.gov\/mmwr\/PDF\/rr\/rr4405.pdf\">first unified childhood immunization schedule<\/a>, the ancestor of today\u2019s familiar grid. For the first time, parents and physicians had a single national standard.<\/p>\n<p>The schedule continued to evolve. ACIP recommended vaccinations for <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/13679791\/\">chickenpox<\/a> in 1996; <a href=\"https:\/\/doi.org\/10.1586\/14760584.2014.877846\">rotavirus in 2006<\/a>, replacing an <a href=\"https:\/\/historyofvaccines.org\/diseases\/rotavirus\">earlier version withdrawn<\/a> after safety monitoring detected a rare side effect; and <a href=\"https:\/\/doi.org\/10.1016\/j.acap.2017.09.014\">HPV, also in 2006<\/a>.<\/p>\n<p>Each addition <a href=\"https:\/\/publichealth.jhu.edu\/2025\/the-committee-behind-american-vaccine-recommendations\">followed the same rigorous process<\/a>: evidence review, risk-benefit analysis and a public vote by the advisory committee.<\/p>\n<h2>More vaccines, less burden<\/h2>\n<p>Vaccine skeptics, including Kennedy, often claim erroneously that <a href=\"https:\/\/theconversation.com\/im-a-physician-who-has-looked-at-hundreds-of-studies-of-vaccine-safety-and-heres-some-of-what-rfk-jr-gets-wrong-259659\">children\u2019s immune systems are overloaded<\/a> because the number of vaccines they receive has increased. This argument is routinely marshaled to argue for a reduced childhood vaccination schedule.<\/p>\n<p>One fact often surprises parents: Despite the increase in recommended vaccines, the number of immune-stimulating molecules in those vaccines, called antigens, has dropped dramatically since the 1980s, which means they are less demanding on a child\u2019s immune system.<\/p>\n<p>The whole-cell pertussis vaccine used in the 1980s alone <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK220490\/\">contained roughly 3,000 antigens<\/a>. Today\u2019s entire schedule <a href=\"https:\/\/theconversation.com\/im-a-physician-who-has-looked-at-hundreds-of-studies-of-vaccine-safety-and-heres-some-of-what-rfk-jr-gets-wrong-259659\">contains fewer than 160 antigens<\/a>, thanks to advances in vaccine technology that allow precise targeting of only the components needed for protection.<\/p>\n<h2>What lies ahead<\/h2>\n<p>For decades, ACIP recommended changes to the childhood schedule only when new evidence or clear shifts in disease risk demanded it. The Jan. 5 announcement represents a fundamental break from that norm: Multiple vaccines moved out of routine recommendations simultaneously, justified not by new safety data but by comparison to a country with a fundamentally different health care system.<\/p>\n<p>Kennedy accomplished this by filling positions involved in vaccine safety with political appointees. His <a href=\"https:\/\/theconversation.com\/rfk-jrs-shakeup-of-vaccine-advisory-committee-raises-worries-about-scientific-integrity-of-health-recommendations-258674\">hand-picked ACIP<\/a> is stacked with members with a <a href=\"https:\/\/globalbiodefense.com\/2025\/06\/23\/rfk-jr-unqualified-acip-overhaul-vaccine-policy-threat\/\">history of anti-vaccine views<\/a>. The authors of the <a href=\"https:\/\/www.hhs.gov\/sites\/default\/files\/assessment-of-the-us-childhood-and-adolescent-immunization-schedule-compared-to-other-countries.pdf\">assessment justifying the change<\/a>, senior officials at the <a href=\"https:\/\/www.theguardian.com\/us-news\/2025\/dec\/31\/tracy-beth-hoeg-fda-vaccines\">Food and Drug Administration<\/a> and <a href=\"https:\/\/www.cidrap.umn.edu\/childhood-vaccines\/days-ahead-acip-meeting-chair-moves-senior-hhs-position\">at HHS<\/a>, are both long-time critics of the existing vaccine schedule. The acting CDC director who signed the decision memo is an <a href=\"https:\/\/thehill.com\/policy\/healthcare\/5478188-who-is-jim-oneill-trumps-new-cdc-director\/\">investor with no clinical or scientific background<\/a>.<\/p>\n<p>The practical effect will be felt in clinics across the country. Routine recommendations trigger automatic prompts in medical records and enable nurses to vaccinate under standing orders. \u201cShared clinical decision-making\u201d requires a physician to be involved in every vaccination decision, creating bottlenecks that will inevitably reduce uptake, particularly for the more than 100 million Americans who lack regular access to primary care.<\/p>\n<p><a href=\"https:\/\/www.beckershospitalreview.com\/quality\/public-health\/states-medical-societies-reject-cdc-panels-revised-hepatitis-b-shot-guidance\/\">Major medical organizations<\/a>, including the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists, have said that they will continue recommending the full complement of childhood vaccines. Several states, including California, New York and Illinois, <a href=\"https:\/\/www.healthbeat.org\/2025\/09\/24\/vaccine-confusion-states-acip\/\">will follow established guidelines<\/a> rather than the new federal recommendations, creating a patchwork where children\u2019s protection depends on where they live.<\/p>\n<p><em>Portions of this article originally appeared in a previous article published on <a href=\"https:\/\/theconversation.com\/rfk-jr-wants-to-scrutinize-the-vaccine-schedule-but-its-safety-record-is-already-decades-long-271408\">Dec. 18, 2025<\/a>.<\/em><!-- Below is The Conversation's page counter tag.
