When the CDC tapped MIT professor Retsef Levi to lead its COVID‑19 Immunization Work Group, many public health experts found this deeply troubling. Levi, an operations researcher by training (not a biomedical or public health specialist) has long expressed alarmist positions on mRNA COVID‑19 vaccines, going so far as to claim they cause “serious harm including death, especially among young people,” and calling for their immediate removal from the market. That a figure with such views would helm a key vaccine policy advisory panel raises urgent questions about both scientific rigor and institutional integrity.
Dislodging the norms of evidence-based review risks fragmenting public guidance, especially when major medical associations have been excluded from the advisory process.
Levi’s public statements go beyond mere professional skepticism; they echo a more radical stance. He has referred to the COVID‑19 shots as potentially the “most failing medical product in the history of medical products.” This isn’t cautious questioning, but a drift toward politicized skepticism.
Moreover, Levi’s landmark study — examining emergency cardiac event calls in Israel during the COVID vaccine roll out— is methodologically flawed. It relied on population-level correlations without knowing whether individuals affected were vaccinated, making its implications murky at best. Independent reviews have flagged this as a textbook case of ecological fallacy — drawing individual-level conclusions from group-level data. In fact, the study’s authors themselves caveated their findings, and the journal added an editor’s note citing ongoing criticisms. Levi has presented the correlation as conclusive proof — a step too far for scientific conservatism.
All this unfolds within a broader overhaul of CDC advisory infrastructure. In June, HHS Secretary RFK Jr. dismissed all 17 ACIP members, replacing them with critics of mRNA vaccines — including Levi, Robert Malone, and Martin Kulldorff. CDC work groups historically relied on neutral, multidisciplinary input, including from institutions like the American Medical Association and the American Academy of Pediatrics. Those voices have now been pushed out in favor of ideological alignment and skepticism.
In short, Levi isn’t just “wrong,” his promotion signals a dangerous reorientation in public health policy. His assertions lack robust supporting data. His leadership role amplifies skepticism at a moment when the public needs clarity, not controversy.
Jake Scott, MD, an infectious disease physician and clinical associate professor at Stanford University who has published responses to Kennedy’s critiques on vaccines, including claims that led the HHS to cancel 22 mRNA vaccine projects, told the New York Times, “I'm concerned that it won't be rigorous science, that it's going to be more statistical manipulation.”
What You Can Do About It
This kind of news can leave people feeling powerless, but there are concrete steps you can take.
First, keep your trust anchored in reputable medical organizations that remain committed to evidence — groups like the American Academy of Pediatrics and the American College of Physicians continue to publish clear, science-based recommendations, even when federal guidance wavers.
Second, share accurate information. Vaccine misinformation thrives in a vacuum; countering it with reputable sources helps protect community trust.
Third, make your voice heard. You can contact your representatives in Congress and express your concern about the politicization of public health agencies — lawmakers can demand oversight.
And finally, model trust in science with your own choices. By keeping yourself and your family up to date with vaccines, you quietly demonstrate that evidence still matters.
The appointment of Retsef Levi is a warning shot about how fragile the machinery of public health can be when ideology takes the wheel, but it’s also a reminder that science isn’t upheld by one panel or one agency alone — it’s upheld by the collective insistence of professionals, patients, and citizens who refuse to let misinformation become policy.
Although not required, any support is greatly appreciated.



I’ve been watching and writing about this disaster in the making. Your point on community and public health is an important message. Thank you for taking the time to write this.
Another awful move by RFK jr
