A new study predicts that policy, if enacted in the Sunshine State, could unleash a wave of measles nationwide on a level not seen in the last 50 years.<\/p>\n<p>Hundreds of pediatric deaths could be anticipated from measles within the next five years across the country, according to the projections published Monday in the Proceedings of the National Academy of Sciences (PNAS), a peer-reviewed journal.<\/p>\n<p>&#8220;We&#8217;re soon going to start seeing children developing severe disease and dying of measles,&#8221; said co-author Abba Gumel, a professor in the Department of Mathematics at the University of Maryland.<\/p>\n<p>Using mathematical models and data from the recent <a href=\"https:\/\/publications.aap.org\/aapnews\/news\/31486\/Unvaccinated-child-dies-of-measles-amid-outbreak?autologincheck=redirected\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">Texas outbreak<\/a>, adapted to Florida\u2019s current conditions, the study shows how relaxing school rules for vaccines could make measles common again in Florida and &#8220;reignite transmission across the United States.&#8221;<\/p>\n<p>Under a worst-case scenario, \u201cFlorida will experience a pronounced measles outbreak within three to five years,\u201d as vaccination rates dip to 82%.<\/p>\n<p>According to the CDC, <a href=\"https:\/\/www.cdc.gov\/measles\/data-research\/index.html\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">88.9% of Florida kindergarteners<\/a> were fully vaccinated in the 2025-26 school year. <\/p>\n<p>The PNAS study uses a a more generous current figure of 91.6% vaccination in Florida, based on the CDC average for the state from 2011-2025.<\/p>\n<p>\u201cThe estimated epidemic peaks will exceed those of any year in the United States since 1977,\u201d with infections \u201cranging between 260 and 315 measles cases per 100,000 children,\u201d said the study. Adult infection rates are projected at about half the rate of children.<\/p>\n<p>Before a measles vaccine was available, <a href=\"https:\/\/www.aap.org\/en\/news-room\/fact-checked\/fact-checked-the-measles-vaccine-is-safe-and-effective\/?srsltid=AU7gw4WoiqgqMcfRIDrXA8cQdCWGouL9x0DfcqW2AcwhM2pfLfi7bduH\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">about 500 people died each year<\/a> in the nation from the disease, which can cause fatal brain swelling and pneumonia.<\/p>\n<p>A vaccine to prevent measles was first licensed in the United States in 1963, and the combined measles, mumps and rubella (MMR) vaccine came on the market in 1971.<\/p>\n<p>But uptake was lax in some areas. The US counted <a href=\"https:\/\/ourworldindata.org\/grapher\/number-of-measles-cases\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">57,345 measles cases<\/a> in 1977. After that, public health officials <a href=\"https:\/\/edcal.acsa.org\/the-school-vaccine-triumph-of-1977\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">began a campaign<\/a> to vaccinate more children, and the disease rate dropped significantly. <\/p>\n<p>Measles cases are rebounding again as more parents opt their children out of the measles, mumps and rubella (MMR) vaccine, even though major medical groups <a href=\"https:\/\/www.aap.org\/en\/news-room\/fact-checked\/fact-checked-the-measles-vaccine-is-safe-and-effective\/?srsltid=AU7gw4WoiqgqMcfRIDrXA8cQdCWGouL9x0DfcqW2AcwhM2pfLfi7bduH\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">insist it is safe<\/a> and effective at preventing measles.  <\/p>\n<p>Effect on children<\/p>\n<p>This year, the United States is seeing the highest number of measles cases in decades &#8212; 3,659 as of Sept. 29, according to the Centers for Disease Control and Prevention &#8212; with recent deadly outbreaks affecting Pennsylvania and Texas.<\/p>\n<p>So far in 2026, Florida has documented 162 cases of measles and no deaths.<\/p>\n<p>&#8220;Repealing the mandate would really, really negatively impact public health as a whole in Florida, but especially the children there,\u201d said Alice Oveson, a PhD student in applied math at the University of Maryland and lead author of the study.<\/p>\n<p>\u201cThe most important result from our projections is that this vaccination is so necessary for the protection of children,\u201d she said.<\/p>\n<p>Already, some counties in Florida are far below the recommended threshold of 95 percent vaccination coverage to maintain herd immunity against measles, which is one of the most contagious diseases.<\/p>\n<p>In Sarasota County, just about 79 percent of kindergarteners are up to date on their shots, according to Department of Health data.<\/p>\n<p>    <img decoding=\"async\" class=\"Image\" alt=\"joseph ladapo talks with ron desantis \"  width=\"880\" height=\"495\" loading=\"lazy\" src=\"https:\/\/www.newsbeep.com\/us-fl\/wp-content\/uploads\/2026\/09\/1790688849_940_.jpeg\"\/><\/p>\n<p>     A prominent Florida doctor expressed dismay that medical leaders in the state have been slow to counter anti-vaccine messages from Surgeon General Dr. Joseph Ladapo out of fear of angering Gov. Ron DeSantis. <\/p>\n<p>Ira Longini, a biostatistician at the University of Florida who was not involved in the research, said the predictions of case counts and deaths could be \u201ca large overestimate.\u201d<\/p>\n<p>The study described its methodology as \u201can age-structured mechanistic model tailored to Florida\u2019s population to quantify the potential impact of removing the MMR school entry vaccination mandate on measles outbreak risk.\u201d<\/p>\n<p>Longini said that\u2019s not necessarily the right approach.<\/p>\n<p>\u201cA simple, deterministic random mixing model with just children and adults is not able to make accurate projections of the number of cases and deaths over time because people simply do not mix randomly on a state level,\u201d Longini said.\u00a0\u201cMeasles comes in sporadic clusters as the coverage goes down and introductions occur.\u201d\u00a0<\/p>\n<p>Instead, a type of modeling that looks at separate habitat areas, called a stochastic patch model, or an agent-based computer model is needed \u201cto predict cases over time, because that is how a disease like measles spreads,\u201d Longini said.<\/p>\n<p>Still, Longini said he agrees with the overall message in the report. Florida\u2019s vaccine policies, championed by Surgeon General Joseph Ladapo, would erode the already low vaccination rate, he said.<\/p>\n<p>\u201cYes, we will see more cases and deaths in both children and adults due to increasing sporadic outbreaks as coverage in children declines and even in vaccinated adults,\u201d he said.<\/p>\n<p>\u201cThe only way to prevent this is to get coverage in children back up to an average of 95% and vaccinate vulnerable adults, but the key is to increase coverage in children and keep it there,\u201d Longini said.<\/p>\n","protected":false},"excerpt":{"rendered":"A year ago, Florida&#8217;s surgeon general said he would spearhead an effort to end all vaccine mandates in&hellip;\n","protected":false},"author":2,"featured_media":413747,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[28,30,29],"class_list":["post-413746","post","type-post","status-publish","format-standard","has-post-thumbnail","category-florida","tag-florida","tag-florida-headlines","tag-florida-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/posts\/413746","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/comments?post=413746"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/posts\/413746\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/media\/413747"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/media?parent=413746"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/categories?post=413746"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-fl\/wp-json\/wp\/v2\/tags?post=413746"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
