<div class="" data-article-body="true">A majority of counties across the U.S. are seeing a steady rise in vaccine exemptions for religious or personal beliefs among children entering kindergarten, a trend that has accelerated since the pandemic, according to a new study.The research, <a href="https://jamanetwork.com/journals/jama/fullarticle/2843870" rel="nofollow noopener" target="_blank" data-ylk="slk:published Wednesday in JAMA;elm:context_link;itc:0;sec:content-canvas" class="link ">published Wednesday in JAMA</a>, is based on a data investigation by NBC News with Stanford University. Mustafa Fattah, medical fellow with NBC News, is lead author on the study.The researchers analyzed data on medical and nonmedical vaccine exemptions for kindergartners collected from 3,053 U.S. counties and jurisdictions (such as school districts and parishes) across 45 states and the District of Columbia from 2010 to 2024.In 2010-2011, the median rate for families opting out of vaccination for religious or personal beliefs nationwide was a scant 0.6%. That number rose to 3.1% by the 2023-2024 school year.In the years following the pandemic, more than 53% of the counties in the study reported an increase of more than 1% in kindergarteners opting out of vaccination for religious or personal reasons.Dr. Nathan Lo, assistant professor of infectious diseases at Stanford University and an author of the study, said the growth in exemptions is “concerning.”“These may look like small numbers, but they may be enough to be the tipping point for something like measles,” Lo said.All states require certain vaccines for children entering public school. They also allow families to opt out of immunization because of medical conditions. Rates of medical exemptions — a doctor’s note that allows children to go to school without the required vaccines — remained stable.States with the highest post-pandemic rate of nonmedical exemptions include Utah, Idaho, Oregon, Wisconsin and Arizona. In parts of Utah and Idaho, post-pandemic exemption rates topped 20%.States such as New York, California, Connecticut and Maine that <a href="https://www.ncsl.org/health/state-non-medical-exemptions-from-school-immunization-requirements#undefined" rel="nofollow noopener" target="_blank" data-ylk="slk:eliminated nonmedical exemptions;elm:context_link;itc:0;sec:content-canvas" class="link ">eliminated nonmedical exemptions</a> saw declines since 2021.The U.S. is already experiencing the largest outbreaks of measles and whooping cough in years, with most cases among school-age children. In Spartanburg County, South Carolina, an outbreak of measles is escalating. At least 434 cases of measles have been reported since September, with more than half diagnosed in the past week.Some schools in Spartanburg County have vaccination rates as low as 20%, Dr. Linda Bell, state epidemiologist for the South Carolina Department of Public Health, said during a news briefing Wednesday.“What’s going on in Spartanburg County now is the best example that even small pockets of under-vaccinated people can result in widespread transmission for this highly infectious virus,” Bell said.Dr. Jesse Hackell, a fellow of the American Academy of Pediatrics said even a small number of vaccine exemptions can contribute to a significant outbreak within a community.“There are many counties where the vaccine rate is between 90% and 95% and that’s low enough to produce a risk for widespread dissemination of a disease,” said Hackell, who was not involved in the study.Dr. Walter Orenstein, professor emeritus at Emory University, said he can’t predict whether exemptions will continue to grow. He points to mistrust of doctors, vaccine misinformation spread on social media and disease elimination itself as contributors to the problem.“Vaccines in a sense, are victims of their own success, because people don’t understand what these diseases are,” he said. “They don’t get to see them, and so they’re not afraid of them.”Orenstein believes confusion and hesitancy around vaccines will only grow following Health Secretary Robert F. Kennedy Jr.’s recent move to <a href="https://www.nbcnews.com/health/health-news/rfk-jr-vaccines-overhaul-kids-denmark-fewer-childhood-shots-rcna250055" rel="nofollow noopener" target="_blank" data-ylk="slk:change the childhood vaccine schedule;elm:context_link;itc:0;sec:content-canvas" class="link ">change the childhood vaccine schedule</a>.Under the new schedule, the Centers for Disease Control and Prevention continues to recommend all children get vaccines for measles, mumps, rubella, polio, pertussis, tetanus, diphtheria, Haemophilus influenzae type B (Hib), pneumococcal disease, HPV and chickenpox.Other vaccines will be recommended for “high-risk” groups or recommended based on what’s called shared clinical decision-making.“My fear is it’s going to take major resurgences of some of these diseases, like polio, before people realize that the benefits of vaccines far, far exceed any risks. And these can be terrible diseases,” Orenstein said.This article was originally published on <a href="https://www.nbcnews.com/health/health-news/vaccine-exemptions-religious-personal-beliefs-study-rcna254082" rel="nofollow noopener" target="_blank" data-ylk="slk:NBCNews.com;elm:context_link;itc:0;sec:content-canvas" class="link ">NBCNews.com</a></div>
