Weekly CDC News Overview – November 23-29, 2025

This is a brief overview of major news about CDC from the past week. In this overview, I describe the major themes from news coverage about CDC, reference important insights and events, and include hyperlinks to all relevant news articles.

Much of this week’s coverage centers on a familiar tactic. Federal officials raise doubts about vaccines or public health interventions by pointing to uncertainties that science can never fully resolve, then portray those unresolved questions as evidence of harm. There are many things we cannot prove are false. That does not make them true. Public health depends on acting on the best available evidence and scientific consensus, not on speculation or innuendo.

CDC leadership changes deepen concerns about agency independence

Louisiana Surgeon General Ralph Abraham has been appointed as CDC’s deputy director, part of a broader restructuring of federal health agencies under MAHA. Reporting highlighted his record of vaccine skepticism, promotion of unproven Covid treatments, and the risk that CDC’s technical decisions will be shaped by politics rather than evidence.

• NPR reported that Louisiana’s top health official, who halted a state vaccine promotion campaign, has been tapped as CDC’s number two leader, prompting concern among clinicians and public health experts.
• USA Today described Ralph Abraham as a “dangerous” vaccine skeptic whose appointment has alarmed vaccine advocates and families that rely on CDC guidance.
• NBC News highlighted Abraham’s past promotion of ivermectin and his role in halting vaccine outreach, noting that critics see his rise at CDC as a direct threat to vaccine confidence.
• Medpage Today detailed how Abraham became one of the country’s top ivermectin prescribers and argued that putting him in CDC’s second highest position undermines the agency’s credibility.
• Ars Technica reported that the new deputy often favors “natural immunity” over vaccination, a stance that conflicts with decades of CDC recommendations.
• Inside Medicine published a detailed account of Abraham’s record, including his role in ending Louisiana’s vaccine media campaigns, and questioned how such a leader could uphold CDC’s scientific standards.
• Louisiana Illuminator noted that there is no clear evidence Abraham is board-certified in family medicine, raising additional questions about his qualifications to lead a science agency.
• The Lancet described CDC as “in critical condition,” arguing that political interference and leadership choices are weakening one of the world’s most important public health institutions.
• Journal of Public Health Management & Practice published a contrasting perspective that framed CDC as the “keystone” of America’s public health system and warned that eroding trust in the agency threatens the entire national infrastructure.
• KFF Health News and Healthcare Dive reported on HHS rescinding shutdown-related layoffs and rehiring staff, but noted that many federal workers now face higher health insurance premiums and ongoing uncertainty about future support.
• Washington Monthly described how the federal government is “ghosting” states and cities on health and social policy, leaving local agencies to manage crises with less federal guidance and fewer resources.

CDC’s false vaccines and autism messaging fuels further mistrust of the agency

The most intense coverage focused on CDC’s website changes about vaccines and autism. Across advocacy groups, clinicians, disability organizations, and local health officials, the message was consistent. The revised language misrepresents the evidence, fuels long debunked claims, and damages trust at precisely the moment CDC needs it most.

• The Los Angeles Times argued that CDC has discarded decades of science by publicizing claims about vaccines and autism that are not supported by evidence, calling the shift “a new low.”
• Ms. Magazine explained what families should know about CDC’s “baseless” new guidance, stating that no credible data show that recommended vaccines cause autism.
• The Post and Courier editorialized that CDC’s wording misleads the public by implying an “alleged link” between vaccines and autism, even though large studies have repeatedly found none.
• The Autistic Self Advocacy Network led a joint statement from autism and disability groups condemning CDC’s page and urging a return to accurate, evidence based communication about vaccines.
• The National Academies of Sciences, Engineering, and Medicine issued a public statement reaffirming that their reviews have found “no evidence that vaccines cause autism” and calling CDC’s new language inconsistent with the scientific record.
• Hays Post reported that Kansas autism researchers are concerned that CDC is spreading misinformation and that the revised website could deepen stigma and confusion for families.
• Science Based Medicine argued that CDC’s page “is lying” about vaccines and autism by presenting fringe views as plausible and ignoring the weight of high quality studies.
• CNN offered an explainer for parents, emphasizing that major medical and scientific bodies agree vaccines do not cause autism and that skipping vaccines puts children at real risk.
• ProPublica described how confusing CDC messaging on vaccines intersects with new research on Covid risk during pregnancy, warning that muddled communication can leave pregnant people less protected.
• MassLive reported that Boston health officials urged residents not to visit CDC.gov for vaccine information, instead directing them to local and state resources they consider more reliable.
• Boston.com covered the Boston Public Health Commissioner’s blunt statement to residents: “Do not trust CDC on vaccines” in light of the autism page changes.
• NBC Boston quoted Massachusetts Governor Maura Healey calling the new website wording “disturbing and sad” because it falsely suggests a link between vaccines and autism.
• Bioethics Today argued that CDC is undergoing “Orwellification,” with political leaders rewriting scientific content in ways that invert the evidence about vaccines and autism.
• Science and Skepticism warned readers not to trust CDC while current leadership is in place, citing the autism page as a prominent example of political messaging displacing science.
• The Boston Globe published an opinion piece from the Health and Human Services Secretary reviewing decades of evidence that vaccines do not cause autism and calling for CDC to correct its website.
• The Wall Street Journal opinion page described the changes at CDC as part of a broader effort by RFK Jr. to turn the agency against vaccines and undermine its own scientific legacy.
• The New York Times podcast “The Daily” examined the “autism diagnosis problem,” situating current disputes over CDC messaging in the context of broader challenges diagnosing autism and supporting families.

FDA, vaccine safety, and the misuse of uncertainty

CDC’s new anti-vaccine messaging is being supported by similarly damaging changes at FDA. A second cluster of stories examined an internal FDA memo that claims Covid vaccines caused the deaths of ten children. Experts emphasized that serious adverse events must be investigated carefully. At the same time, they warned that overstating uncertain associations can lead to overly restrictive rules that delay vaccines and cost lives.

• STAT reported that experts say a senior FDA official’s claim that Covid vaccines caused children’s deaths requires far more evidence and that current data do not prove causation.
• NPR described FDA’s plan to raise hurdles for vaccine approval, based partly on the contested memo, and noted concerns that higher barriers could slow responses to future respiratory threats.
• The Guardian quoted experts who called the strict new FDA protocol for vaccines “dangerous and irresponsible,” warning it may deter innovation and limit access to lifesaving products.
• Medpage Today summarized the disputed memo linking ten child deaths to Covid shots and highlighted pediatricians’ concern that the document is being misused to justify sweeping policy changes.
• The Washington Post reported that FDA will impose strict new vaccine requirements, framed as a response to child Covid vaccine deaths, even as independent scientists argue that causality has not been established.
• KFF Health News detailed how RFK Jr. has sharpened attacks on vaccine ingredients like aluminum, without scientific backing, fueling public anxiety that FDA and CDC then have to address.
• CBS News similarly reported that Kennedy continues to question vaccine safety despite extensive data showing that current vaccines meet rigorous safety standards.
• Los Alamos Daily Post published an op ed asking “Who can you trust” about vaccines and argued that clear, consistent communication from agencies like CDC and FDA is essential to counter misinformation.
• The Wall Street Journal and The Globe and Mail both framed the current moment as a travesty, arguing that one of the world’s great public health agencies is being dismantled by political attacks on vaccines.

Outbreaks across the country as CDC’s stature and capacity diminish

While leaders debate hypothetical vaccine risks, real outbreaks continue. Measles, pertussis, HIV, botulism, and avian influenza all appeared in coverage this week. These stories show the cost of delayed vaccination, weak regulation of unsafe products, and mixed messages about risk.

• KFF Health News reported that a South Carolina measles outbreak illustrates the chilling effect of vaccine misinformation, with hesitant parents citing national debates when declining shots.
• WRDW noted that the same outbreak has reached at least 62 cases as holiday travel continues, raising concern about further spread.
• NBC News described surging measles as a “fire alarm” for other vaccine preventable diseases that could be next if coverage continues to slip.
• USA Today network reported that Florida officials will review school vaccine requirements amid calls to repeal mandates, a move that could further weaken herd immunity.
• PBS NewsHour covered persistently elevated whooping cough cases as vaccination rates fall, pointing to the risks for infants and pregnant people.
• Axios described pertussis as a “dangerous cough threat” already surging ahead of winter, citing rising cases in Kentucky.
• CIDRAP reported that a third infant in Kentucky has died from whooping cough, while national pertussis cases remain high for a second consecutive year.
• WLWT provided additional local detail about the Kentucky deaths and emphasized the importance of maternal vaccination.
• Spectrum News noted that an HIV outbreak in Penobscot County, Maine, continues to grow and highlighted gaps in prevention and harm reduction resources.
• Medpage Today reported that a Washington State resident has died from a rare bird flu strain, a reminder of the ongoing risk of zoonotic spillover.
• MMWR published notes from the field on severe illnesses after self injection of botulinum toxin purchased online, underscoring the dangers of unregulated products.
• CBS News reported that infant formula maker ByHeart warned all its products may be tainted with botulism, triggering recalls and anxiety among families.
• The Journal of the International AIDS Society published a commentary titled “This is not normal,” calling for renewed HIV activism as outbreaks and funding gaps grow.

Evidence that vaccines prevent severe disease, cancer, and complications

Even as misinformation spreads, data continue to show that vaccines prevent not only acute infections but also cancer and chronic complications. This week’s stories provided an important counterweight to claims that “we cannot be sure” vaccines are beneficial.

• The Washington Post reviewed common vaccines that can prevent some chronic diseases and cancers, highlighting HPV, hepatitis B, and other routine immunizations.
• Medpage Today reported that HPV vaccination is tied to a large reduction in cervical cancer risk, adding to a robust body of evidence.
• Cochrane summarized new research confirming that HPV vaccines prevent cervical cancer, reinforcing current recommendations.
• Bloomberg framed the new HPV data as a tool in the battle against misinformation, arguing that clear evidence of cancer prevention should be central to public communications.
• BlueSky posts noted that Australia recorded zero cervical cancer cases in women under 25 for the first time since 1982, a milestone attributed in part to HPV vaccination.
• MedicalXpress reported that RSV vaccines could offer protection against asthma, suggesting benefits beyond prevention of acute respiratory infection.
• CIDRAP described an experimental mRNA flu vaccine that showed superior efficacy against symptomatic illness compared with existing options.
• STAT reported that global measles vaccination levels are nearly back to pre pandemic levels, although many countries still have large immunity gaps.
• Gavi announced that Ethiopia introduced a birth dose hepatitis B vaccine, a major step toward preventing mother to child transmission.
• PAHO highlighted new regional collaboration in Latin America and the Caribbean to expand research, development, and production of vaccines and other mRNA based health technologies.
• Reuters reported that WHO is urging countries to integrate infertility care into national health services, illustrating how vaccines and reproductive health services intersect in comprehensive care.
• The Boston Globe published an editorial on “three things in public health to be thankful for,” including vaccines, which have dramatically reduced child deaths over the past century.

Federal policy, workforce, and the future of public health capacity

The week’s reporting also described broader shifts in federal health policy and workforce. We are progressively seeing the impact of an under resourced system, buffeted by political directives, at the same time that communities are facing higher costs and more complex risks.

• The Hill reported that HHS officially rescinded shutdown layoffs, restoring employees whose jobs had been cut during budget standoffs.
• GovExec covered former federal employees who are working to “reimagine government” after the shutdown, including how agencies like CDC can rebuild capacity and trust.
• KFF Health News described how federal workers, including those at CDC, now face steep health insurance premium increases that may affect recruitment and retention.
• WSPA and NPR reported that new loan rules are cutting aid for nursing and medical students, prompting warnings that the physician and nurse pipeline will narrow.
• Politico described a health care backlash in Georgia as insurance subsidies are set to expire, putting pressure on Republicans who previously opposed the Affordable Care Act.
• The New York Times reported that some former opponents of Obamacare now want to preserve subsidies, illustrating how health coverage has become politically durable.
• CNN detailed the new “America First Global Health Strategy,” which experts warn is risky because it reduces support for multilateral efforts that have long complemented CDC’s global work.
• AVAC noted that PEPFAR negotiations and Global Fund replenishment have fallen short, while chaos at CDC and NIH adds to uncertainty in the global HIV response.
• To End a Plague…Again wrote that the United States has effectively “canceled” World AIDS Day, reflecting shifting priorities away from HIV at a critical moment.
• The Washington Post reported that EPA will abandon a fine particle pollution rule that would have prevented thousands of deaths, a decision with major implications for population health.
• The Boston Globe and other outlets stressed that even amid these setbacks, past investments in public health have saved millions of lives, underscoring what is at stake if current systems erode.

Across these stories, a pattern emerges. Claims that “we cannot rule out harm” are repeatedly used to undermine confidence in vaccines and public health agencies, even when the best available evidence shows that vaccines are safe and highly effective. At the same time, outbreaks and policy reversals demonstrate the very real harms of inaction. The challenge for CDC and its partners is not to prove every unfounded claim false. It is to act decisively on what we already know to be true.
