Former CDC immunizations chief: ‘I only see harm coming’ with RFK Jr. leading HHS

Firewall between science and ideology ‘has completely broken down’: Fmr. CDC official

Former Centers for Disease Control and Prevention (CDC) immunizations chief Dr. Demetre Daskalakis said Sunday that he’s concerned with the direction the agency is going and worried about public health going forward.

Daskalakis, who served as director of the National Center for Immunization and Respiratory Diseases, submitted his resignation from the CDC on Wednesday in protest following the Department of Health and Human Services (HHS) removing CDC Director Susan Monarez from her position. In his resignation letter, Daskalakis denounced HHS Secretary Robert F. Kennedy Jr.'s leadership of both the HHS and the CDC.

“From my vantage point as a doctor who's taken the Hippocratic Oath, I only see harm coming. I may be wrong, but based on what I'm seeing, based on what I've heard with the new members of the Advisory Committee for Immunization Practices, or ACIP, they're really moving in an ideological direction where they want to see the undoing of vaccination," Daskalakis told ABC News' "This Week" co-anchor Martha Raddatz.

Daskalakis disagreed with changes to recommendations on who should get the new COVID-19 vaccine this fall, with the new dosage has been approved only for people aged 65 and up and children and adults with underlying health conditions that put them at high risk, creating confusion and uncertainty for people who want the latest vaccination who don’t meet these parameters.

Daskalakis said there is now no separation of political ideology and science with Kennedy leading HHS.

“I didn't think that we were going to be able to present science in a way free of ideology, that the firewall between science and ideology has completely broken down. And not having a scientific leader at CDC meant that we wouldn't be able to have the necessary diplomacy and connection with HHS to be able to really execute on good public health,” Daskalakis said in explaining why he resigned.

Former acting CDC Director Dr. Richard Besser, now president and CEO of the Robert Wood Johnson Foundation, told Raddatz he’s heavily concerned amid the major shakeup at the CDC.

“The difference is going to be profound. The CDC is an absolutely critical piece of the protection for Americans from any public health threat. Now, with the director being removed, senior leadership leaving, I have great fears for what will happen to this country the next time we face a public health emergency, whether it's a massive earthquake, a new infectious agent or, unfortunately, the next pandemic,” Besser said.

Besser also has concerns on how Kennedy's opposition to vaccine mandates is going to impact public health.

“When I think about mandates, I think about children going to school. I think about young parents who are sending their children to school and want to know that their children are safe, and the way children are safe from vaccine-preventable diseases is by getting vaccinated themselves. But no vaccine is 100%. And so you count on the other children in that classroom being vaccinated. I think with this secretary, we are on a path to it being largely parental choice, and that is going to put at risk those people for whom the vaccine didn't work and children who may have medical conditions where they can't get vaccinated. That is a major step backwards for public health,” Besser said.
