The U.S. Health Secretary Robert F. Kennedy Jr. on Wednesday unveiled eight new members to the Advisory Committee on Immunization Practices (ACIP), days after abruptly dismissing the previous 17-member panel. Health and Me had previously reported on the JFK Jr.'s decision to 'retire' the existing members of the ACIP. This move has stirred concern among doctors, scientists, and public health groups, who fear Kennedy is steering federal vaccine policy in a direction driven more by ideology than science.The new appointments include individuals known for their skepticism about mainstream vaccine science, including critics of COVID-19 vaccines and public health measures implemented during the pandemic.A Shift in Tone and CredentialsAmong the new advisers is Dr. Robert Malone, a scientist who once worked on mRNA vaccine technology and later gained notoriety for promoting conspiracy theories about COVID-19 vaccines. Malone has suggested that Americans were “hypnotized” into taking vaccines and claimed the shots cause a form of AIDS—both statements widely debunked by scientific communities.Also joining the panel is Dr. Martin Kulldorff, a co-author of the controversial Great Barrington Declaration that argued against pandemic lockdowns, and Dr. Cody Meissner, a pediatric infectious disease expert who previously served on both ACIP and the FDA’s vaccine advisory panel.Vicky Pebsworth, a regional director for the National Association of Catholic Nurses and former board member of the National Vaccine Information Center—often cited for spreading vaccine misinformation—was also appointed.Concerns About Qualifications and BiasPublic health experts expressed alarm over the new composition. “The previous ACIP was made up of technical experts who have spent their lives studying vaccines,” said Abram Wagner, a University of Michigan public health researcher. “Most people on the current list don’t have the technical capacity we expect from those making complex, science-driven decisions.”Wagner added that the inclusion of Pebsworth was “incredibly problematic,” due to her association with groups accused of spreading vaccine misinformation.Despite public concerns, Kennedy stated the committee would not be composed of “anti-vaxxers” but of “credentialed scientists.”ALSO READ: RFK Jr. Removes Entire CDC Vaccine Advisory CommitteeA Closer Look at the AppointeesOther appointees include:Dr. James Hibbeln, a former NIH neuroscientist focused on nutrition and brain health.Retsef Levi, an MIT operations management professor who called for an end to the COVID-19 vaccine program in a 2023 video.Dr. James Pagano, an emergency medicine physician from Los Angeles.Dr. Michael Ross, a Virginia-based obstetrician and gynecologist.Dr. Meissner, arguably the most experienced in vaccine policy among the new members, served on ACIP and the FDA’s vaccine advisory committee. During his term, he notably voted against broad booster recommendations in 2021—a decision later overturned by the FDA.Changing Course on Public Health PolicyThe ACIP, created in 1964, advises the CDC on how to use FDA-approved vaccines. While Kennedy promised during his Senate confirmation to uphold the vaccination schedule, he has since overridden ACIP’s guidance. In May, he independently altered COVID-19 vaccine recommendations for children and pregnant women.On Monday, he dismissed all 17 existing ACIP members, pledging to install a new team before the committee’s next meeting in late June. The upcoming agenda includes key decisions on vaccinations for flu, COVID-19, HPV, RSV, and meningococcal disease.Kennedy, long a polarizing figure in the vaccine debate, has accused the former panel of being too aligned with pharmaceutical companies. Critics warn that his restructured committee may prioritize politics over public health science.
