Kennedy Jr. on Wednesday named eight doctors and researchers, including two prominent critics of federal scientists and the Biden administration’s Covid vaccine policies, to replace roughly half the members he fired from an expert panel that advises the Centers for Disease Control and Prevention.</p><p class="css-at9mc1 evys1bk0">Mr. Kennedy made the announcement Wednesday <a class="css-yywogo" href="https://x.com/SecKennedy/status/1932899858920120692" rel="noopener noreferrer" target="_blank" title="">on the social media platform X</a>, two days after he <a class="css-yywogo" href="https://www.nytimes.com/2025/06/09/health/rfk-jr-cdc-vaccine-panel.html" title="">fired all 17 members</a> of the Advisory Committee on Immunization Practices.</p><p class="css-at9mc1 evys1bk0">“The slate includes highly credentialed scientists, leading public-health experts, and some of America’s most accomplished physicians,” he wrote. In a post on X late Tuesday night, Mr. Kennedy promised he would not appoint “ideological anti-vaxxers.”</p><p class="css-at9mc1 evys1bk0">But the appointments of at least two of the new members — Martin Kulldorff and Dr. Robert Malone — are likely to draw an uproar from pro-vaccine groups. Both were highly critical of President Joseph R. Biden Jr.’s coronavirus vaccine policies during the pandemic.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-1"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-1"><div class="css-53u6y8"><p class="css-at9mc1 evys1bk0">Dr. Kulldorff, a Swedish biostatistician and former Harvard professor who in the past advised the C.D.C. on vaccine safety, opposed vaccine mandates. He came to prominence in 2020 as a co-author of the Great Barrington Declaration, a document that opposed lockdowns and drew intense backlash from Dr. Anthony S.
