The findings were consistent with what researchers have found in past years, that the vaccine can help reduce the risk of severe illness in adults even after accounting for immunity from prior vaccination or infection.<\/p>\n<div><\/div>\n<p>\u201cScience was never the issue,\u201d said Michelle Barron, one of the study\u2019s authors and senior medical director of infection prevention and control for UCHealth, a nonprofit health system in Colorado. \u201cCertainly it was within [the CDC\u2019s] purview to keep it out, for whatever reason, but it was clearly not for scientific reasons that the study was withheld from publication in the MMWR.\u201d<\/p>\n<div><\/div>\n<div><\/div>\n<div><\/div>\n<p>Jay Bhattacharya, CDC\u2019s interim director, delayed publication of the study before it was subsequently not published in the MMWR at all, The Washington Post previously reported. Bhattacharya had concerns about the methods used to calculate vaccine effectiveness, a Health and Human Services spokesman said at the time.<\/p>\n<div><\/div>\n<p>Barron said she believed the study was not published because the findings did not support Health Secretary Robert F. Kennedy Jr.\u2019s agenda that wants to limit the use of COVID vaccine specifically.<\/p>\n<div><\/div>\n<div><\/div>\n<p>Kennedy, the founder of a prominent anti-vaccine group, has been an outspoken critic of COVID shots, once referring to them as the \u201cdeadliest vaccine ever made.\u201d<\/p>\n<div><\/div>\n<p>A spokeswoman for the Health and Human Services Department did not directly address the author\u2019s allegation Tuesday that the paper was withheld because it conflicted with the administration\u2019s vaccine agenda. Spokeswoman Emily Hilliard said the CDC evaluates studies using rigorous scientific methods and reviews methodological concerns before publication.<\/p>\n<p>Read more <a href=\"https:\/\/corporate-movers-usa.com\/?p=1448\">What to know about the Invitational Clash, a pro-am basketball tourney promoting community wellness<\/a><\/p>\n<div><\/div>\n<p>\u201cThe CDC does not make scientific determinations based on predetermined conclusions,\u201d Hilliard wrote in an email. \u201cWe evaluate the weight of evidence using rigorous methods, communicate uncertainty and limitations, and subject our work to scientific scrutiny before publication.\u201d<\/p>\n<div><\/div>\n<p>A commentary accompanying Tuesday\u2019s JAMA Network Open report said the methodology in question, known as test negative design, has limitations, like any study. But those shortcomings are well understood, actively studied, and outweighed by the method\u2019s practicality for routine vaccine-effectiveness monitoring, wrote Natalie Dean, associate professor of biostatistics and epidemiology at Emory University\u2019s Rollins School of Public Health.<\/p>\n<div><\/div>\n<div><\/div>\n<p>\u201cThis is not a controversial study design \u2014 this is [the] same design that has been churning out vaccine results for a long time,\u201d Dean wrote in an email. \u201cAnd from a highly experienced group \u2014 CDC plus a network of top vaccine researchers across the country. They are a well-oiled machine.\u201d<\/p>\n<div><\/div>\n<p>She added: \u201cThere was no scientific reason to reject this paper. It had undergone internal review, and it clearly meets the standards of peer-reviewed science. It makes my colleagues on edge to see political interference in the scientific process.\u201d<\/p>\n<div><\/div>\n<p>Dean said the methodology is being \u201cunfairly maligned\u201d and worried that efforts to discard it could weaken the nation\u2019s vaccine surveillance system. \u201cThen we\u2019ll be flying blind with respect to influenza, COVID, and RSV vaccine monitoring,\u201d she said.<\/p>\n<div><\/div>\n<p>Between September and December last year, healthy adults who received the COVID-19 vaccine reduced their likelihood of emergency department and urgent care visits by 50% and cut the likelihood of COVID-associated hospitalizations by 55%, compared with those not receiving a 2025-26 vaccine dose, the report found.<\/p>\n<div><\/div>\n<p>Researchers analyzed data from a CDC-funded surveillance network to compare data on adults who sought medical care for COVID-like symptoms and compared outcomes between those who received the updated 2025-26 vaccine and those who had not.<\/p>\n<p>Read more <a href=\"https:\/\/corporate-movers-usa.com\/?p=1446\">Westtown\u2019s Jordyn Palmer, Bonner-Prendie\u2019s Korey Francis named state\u2019s Miss and Mr. basketball<\/a><\/p>\n<div><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>A professor who wrote an accompanying commentary said she worried efforts to discard the study&#8217;s design methodology could weaken the U.S. vaccine surveillance system. <\/p>\n","protected":false},"author":1,"featured_media":1451,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-1452","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>CDC\u2019s chief blocked a COVID vaccine study.
