They\u2019re important for kids to be thriving and healthy in schools,\u201d Dr. Erica Pan, director of the California Department of Public Health and the state public health officer, said of vaccines. And she credited California\u2019s robust vaccine requirements as a condition of enrollment for schoolchildren as a reason why the state so far has kept a lid on the huge outbreaks of measles seen in other parts of the nation.<\/p>\n<p>Her full-throated defense comes after President Trump issued <a class=\"link\" href=\"https:\/\/www.latimes.com\/science\/story\/2026-08-10\/trump-to-sign-executive-order-calling-for-spacing-out-childhood-shots\">an executive order<\/a> Monday recommending that the singular measles, mumps and rubella, or MMR, vaccine should be separated into three and that all childhood immunizations should be given at separate visits \u201cto the maximum extent feasible.\u201d<\/p>\n<p>\u201cWe want it in three separate vaccinations, given at separate times,\u201d he said during the signing ceremony. \u201cTogether, there could be a possibility they\u2019re quite lethal. And separately it looks like they are not at all lethal, but just very effective.\u201d <\/p>\n<p>The American Academy of Pediatrics blasted the order as \u201cunscientific and dangerous,\u201d and criticized comments made by administration officials suggesting a link between autism and vaccines \u2014 a claim that has been discredited by many studies.<\/p>\n<p>\u201cDozens of studies involving millions of people show there is no link between vaccines and autism, and yet federal leaders continue to promote this outdated, disproven idea to scare families,\u201d said the academy\u2019s president, Dr. Andrew Racine. <\/p>\n<p>The Infectious Diseases Society of America has been equally unequivocal. <\/p>\n<p>\u201cThe MMR vaccine does not cause autism,\u201d the group says on <a class=\"link\" href=\"https:\/\/www.idsociety.org\/ID-topics\/infectious-disease\/measles\/know-the-facts\" target=\"_blank\">an online fact page<\/a>, adding that the measles vaccine prevents thousands of deaths a year worldwide.<\/p>\n<p>Pan said Trump\u2019s executive order does not change vaccine requirements for schoolchildren in California. And insurance companies continue to cover vaccinations for schoolchildren. <\/p>\n<p>When Trump was asked whether there was any evidence for his claims regarding the MMR vaccine, he answered: \u201cNo. What I\u2019ve heard is that there are some people that say it is that way, and I say, \u2018Well, let\u2019s say there\u2019s a 5% chance of it. Let\u2019s split it up.\u2019 \u201d<\/p>\n<p>There is no evidence to back up those assertions, medical organizations and mainstream experts say. The first version of the combination MMR shot was <a class=\"link\" href=\"https:\/\/publichealth.jhu.edu\/2025\/vaccines-do-not-cause-autism\" target=\"_blank\">approved<\/a> in 1971, and versions of it have been given to <a class=\"link\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC4866980\/\" target=\"_blank\">hundreds of millions of children safely<\/a> over several generations, with more than 90% of children receiving the shot nationally, experts say. <\/p>\n<p>Combining protection against the three diseases has been considered a miracle of modern medicine. Before the vaccine era, hundreds of children a year in the U.S. were either killed by measles or suffered swelling of the brain as a result of the disease. Tens of thousands were also hospitalized each year. <\/p>\n<p>Mumps can cause deafness and inflame the brain, pancreas, testicles, ovaries and breast tissue. And rubella risks causing severe birth defects in pregnant women. <\/p>\n<p>\u201cThere is no data supporting doing this in separate shots,\u201d Pan said. \u201cAnd, in fact, it will take more visits and more pokes in the arm, literally, for children to do this.\u201d<\/p>\n<p>With vaccination rates declining in many parts of the country, measles has resurged in the U.S. in the past two years, resulting in the first child deaths from the disease in <a class=\"link\" href=\"https:\/\/www.latimes.com\/california\/story\/2026-07-24\/measles-cases-us-record\">22 years,<\/a> as well as hundreds of pediatric hospitalizations. <\/p>\n<p>So far this year, there have been 2,566 cases of measles nationwide, which is already more than the 2,289 reported in all of 2025, <a class=\"link\" href=\"https:\/\/www.cdc.gov\/measles\/data-research\/index.html\" target=\"_blank\">according to data<\/a> from the U.S. Centers for Disease Control and Prevention. The most recent case count is also higher than any calendar year since 1991 \u2014 the final year of the nation\u2019s last measles epidemic. <\/p>\n<p>Beyond scheduling difficulties for parents, clinics and doctors\u2019 offices, no company even makes separate immunizations for measles, mumps and rubella, Pan said. \u201cThere\u2019s no scientific basis for it. There\u2019s no current availability to do that.\u201d<\/p>\n<p>Trump\u2019s executive order further recommends that children should get vaccinated against 11 diseases, a reduction from the 18 currently recommended by the CDC. The order also suggested that his administration would challenge certain states\u2019 laws that require vaccination as a condition of entry into schools.<\/p>\n<p>California in 2015 enacted a law that strengthened vaccine requirements for schoolchildren. The law ended the ability of parents to cite personal beliefs in seeking to exempt their children from certain vaccinations. <\/p>\n<p>Children can still be exempted and attend school in California if they <a class=\"link\" href=\"https:\/\/www.latimes.com\/science\/sciencenow\/la-sci-sn-vaccine-medical-exemptions-20170905-story.html\">have a medical reason<\/a>. And California law does allow parents to skip immunizations for children who are enrolled in independent study programs and do not receive classroom-based instruction.<\/p>\n<p>California\u2019s law was passed following <a class=\"link\" href=\"https:\/\/www.latimes.com\/newsletters\/la-me-ln-essential-california-20190507-story.html\">a large measles outbreak<\/a> centered at Disneyland that resulted in 131 cases in California alone, and spread to six other states, as well as Canada and Mexico. At least 12 of those infected in California were infants <a class=\"link\" href=\"https:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/mm6406a5.htm\" target=\"_blank\">too young<\/a> to be vaccinated.<\/p>\n<p>After the law passed, California saw its measles vaccination rates improve. In 2013, the vaccination rate among California kindergartners hit a low of 92.3%, below the 95% threshold doctors say is needed to keep a lid on outbreaks. Since the law <a class=\"link\" href=\"https:\/\/www.latimes.com\/local\/lanow\/la-me-ln-california-vaccination-20170412-story.html\">took<\/a> effect, that rate has ranged between 95.1% and 97.3%.<\/p>\n<p>The most recent figure was 96.1% for the 2024-25 school year.<\/p>\n<div class=\"enhancement\" data-click=\"enhancement\" data-align-left=\"\">  <ps-interactive-project class=\"interactive-project block\" data-use-responsive-height=\"true\" data-module-id=\"0000019f-ffa8-de60-a5df-ffbdd0430005\">\n<div data-wc-src=\"https:\/\/datawrapper.dwcdn.net\/zEGJr\/embed.js?v=7\" style=\"min-height:533px;\">     <noscript><picture><source type=\"image\/webp\" srcset=\"https:\/\/ca-times.brightspotcdn.com\/dims4\/default\/f7be5df\/2147483647\/strip\/true\/crop\/690x1066+0+0\/resize\/320x494!\/format\/webp\/quality\/75\/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2F3c%2F95%2Fc54254ed45b0bf545ac1382bc095%2Fd586207d90c24ae29c442a06d9ac8053 320w,https:\/\/ca-times.brightspotcdn.com\/dims4\/default\/873424f\/2147483647\/strip\/true\/crop\/690x1066+0+0\/resize\/568x878!\/format\/webp\/quality\/75\/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2F3c%2F95%2Fc54254ed45b0bf545ac1382bc095%2Fd586207d90c24ae29c442a06d9ac8053 568w,https:\/\/ca-times.brightspotcdn.com\/dims4\/default\/10a7243\/2147483647\/strip\/true\/crop\/690x1066+0+0\/resize\/768x1187!\/format\/webp\/quality\/75\/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2F3c%2F95%2Fc54254ed45b0bf545ac1382bc095%2Fd586207d90c24ae29c442a06d9ac8053 768w,https:\/\/ca-times.brightspotcdn.com\/dims4\/default\/4274487\/2147483647\/strip\/true\/crop\/690x1066+0+0\/resize\/1024x1582!\/format\/webp\/quality\/75\/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2F3c%2F95%2Fc54254ed45b0bf545ac1382bc095%2Fd586207d90c24ae29c442a06d9ac8053 1024w,https:\/\/ca-times.brightspotcdn.com\/dims4\/default\/1b87694\/2147483647\/strip\/true\/crop\/690x1066+0+0\/resize\/1200x1854!\/format\/webp\/quality\/75\/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2F3c%2F95%2Fc54254ed45b0bf545ac1382bc095%2Fd586207d90c24ae29c442a06d9ac8053 1200w\" sizes=\"100vw\"\/><img class=\"image\" alt=\"Chart shows California measles vaccination rates among kindergartners since 1998.
