Scandalous revelation from the newspaper Washington Post: the director of the CDC, Jay Bhattacharya, allegedly blocked the publication of official scientific research showing that COVID-19 vaccines dramatically reduce hospitalizations and emergency room visits. The case goes far beyond an academic disagreement over methodology — it goes to the heart of science’s independence from political will.
What the Hidden Study Revealed
The research was scheduled to be published in March 19 2026 on Morbidity and Mortality Weekly Report (MMWR) — CDC's leading scientific journal on topics public healthThe team of epidemiologists at the National Center for Immunization and Respiratory Diseases had already completed the scientific review and the article had received approval from the editors of MMWR.
The findings spoke for themselves:
- Adults who received the updated COVID-19 vaccine for the period 2025–26 reduced the likelihood of emergency department visits by Up to 50%
- Hospital admissions decreased by 55% compared to unvaccinated adults
- The data covered the period September–December 2025
- The was used test-negative design — methodology widely used by the CDC for years
This wasn't unpublished preliminary data. The research had already passed the peer review stage. Something else—and someone specific—stopped it.
Who Blocked the Post — and Why?
According to government officials who spoke anonymously to Washington Post and its NBC News, Bhattacharya reviewed the report and froze its publication. Official justification: "concerns about methodology."
The problem with this explanation is relentless: the exact same methodology is used systematically by the CDC to evaluate influenza vaccines and other respiratory virus vaccines. Neither now nor ever in the past has anyone at the organization questioned it in the context of MMWR publication.
In late March, CDC epidemiologists presented Bhattacharya with a detailed update on the test-negative design, explaining why alternative methodologies are less effective. No decision on publication has been made — yet. If the article doesn’t see the light of day in MMWR, researchers can submit it to an independent medical journal.
Who is Jay Bhattacharya?
Bhattacharya is no stranger to those following the scientific debates surrounding the pandemic. In 2020, he was one of the authors of Great Barrington Declaration — the controversial “herd immunity” proposal that promoted exposure of young and healthy individuals to the virus while isolating vulnerable groups. This approach was rejected by the majority of the international scientific community.
Ως director of the NIH later, he wrote to Washington Post that mRNA technology "failed to gain public trust," while defending RFK Jr.'s decision to cut $ 500 million from funding mRNA vaccine research.
It is worth noting that in internal meetings with CDC officials he has spoken in favor of the usefulness of other vaccines — such as measles. The issue, then, is not universal opposition to vaccinations, but selective treatment — and that is precisely what worries the scientists.
RFK Jr. and the Anti-Vaccination Agenda
To understand why this publication delay is so significant, the broader political context is needed. The Robert F Kennedy Jr, as Minister of Health, is one of the most persistent critics of vaccines in USAHe has called COVID-19 vaccines "the deadliest vaccine ever made" — a statement that is completely contradicted by dozens of independent scientific studies.
In this climate, an official government study proving that vaccines dramatically reduce hospitalizations and emergency room visits directly opposes the Trump administration's rhetoricIt is not surprising, therefore, that government officials see this delay as politically motivated.
The public health implications are tangible: when the effectiveness of vaccines is unjustifiably questioned, vaccination rates decrease and vulnerable populations are exposed to serious diseases. It is precisely this kind of inaction in the face of documented risks that is analyzed in our article on the shingles, which turns out to be much more dangerous than we thought.
The Case of Blood Clots: How Science Works Properly
For a balanced picture, it is also worth mentioning the well-documented side effects of some vaccines. A study in New England Journal of Medicine explained in detail the mechanism behind the rare thrombosis associated with adenoviral vaccines (AstraZeneca, Johnson & Johnson):
- An adenovirus protein triggers antibody production in people with a specific genetic profile and a specific mutation in B-cells
- These antibodies bind to the protein PF4 instead of targeting the virus
- This triggers a chain reaction (VITT) that in an extremely small number of people can lead to serious thrombosis.
The discovery of the mechanism allowed science to develop treatment protocols. This is science in action: transparency, discovery, improvementThe way in which research leads to better treatments is also highlighted by recent successes, such as the cell therapy that changed the way the immune system works.
The Methodology That "Couldn't Stand" Auditing
The test-negative design compares vaccinated and unvaccinated people being tested for COVID-19, minimizing selection bias that would skew the results. It’s not just an acceptable method — it’s the gold standard for studies of vaccine efficacy against viral diseases, where large-scale randomized trials are not feasible on an annual basis.
The Ministry of Health spokesperson argued that “it is standard practice to have a dialogue on the best methodology before publication.” The essential difference — which he omitted — is that the article had already received formal scientific approval from the editors of MMWR, something extremely unusual to be overturned by a political appointee.
What's at Real Stake?
This case raises a question that concerns everyone: Who decides what scientific data reaches the public? If the answer is “political appointees with a specific agenda,” then the credibility of public health organizations — which takes years to build and minutes to collapse — is at risk.
Science never claims that vaccines are infallible. It claims that data should be objectively evaluated and communicated transparently. Studies that review and debunk myths — like those examined in our article on vaccines — are scientific findings that overturn established beliefs — are the cornerstone of proper information.
The truth is difficult to "bury" forever — especially when there are independent scientists and a free press who refuse to be silent.
