The acting CDC director, Jay Bhattacharya, reportedly delayed nan report’s publication owed to concerns surrounding nan research’s methodology.

“This is decidedly an escalation of this administration’s undermining of CDC science,” said Dr Fiona Havers, a erstwhile elder advisor connected vaccine argumentation astatine nan CDC. “The truth that they are now blocking this is highly concerning.”
Havers resigned from nan CDC past year, successful consequence to nan Trump administration’s approaches to vaccine policy.
The CDC’s investigation recovered that betwixt September and December of 2025, patient adults who received nan vaccine reduced their likelihood of Covid-related hospitalizations by 55%, according to nan Post’s report.

The methodology successful mobility has been utilized for countless studies by nan CDC for astir 2 decades, according to Havers and nan Post’s reporting. The methodology, known arsenic “test-negative design”, compares patients who are already sick and their vaccination rates. Because CDC argumentation is to urge that group return nan Covid vaccine, performing a placebo effect trial would beryllium unethical, Havers explained.
Just a week earlier nan study was expected to beryllium published, a abstracted study astir nan flu vaccine and its effectiveness was published successful nan Morbidity and Mortality Weekly Report, nan CDC’s journal.

During nan tallness of nan Covid-19 pandemic successful 2020, Bhattacharya opposed lockdowns and disguise mandates. He was nominated by Trump successful 2024 to nonstop nan National Institutes of Health (NIH). He stepped successful arsenic CDC head successful February of this year.
“It’s regular for CDC activity to reappraisal and emblem concerns astir MMWR papers, particularly relating to their methodology, starring up to planned publication,” a CDC spokesperson told nan Washington Post. The spokesperson added that Bhattacharya was concerned astir “the observational method utilized successful nan study to cipher vaccine effectiveness, and nan technological squad is moving to reside these concerns”.
Kennedy’s assignment to lead HHS has created a important shakeup wrong nan section and its aggregate agencies. Last year, Kennedy fired each 17 members of a vaccine advisory committee and replaced a fewer pinch members who are seemingly besides opposed to vaccines.
A number of CDC employees, including Havers, person resigned successful protestation of Kennedy’s actions.
