Quashed studies, halted publications and canceled research threaten damage to public health, critics saySign up for the Breaking News US newsletter email A series of high-profile and under-the-radar decisions by US health agencies have scientists and doctors questioning the extent of the agencies’ control over public communications – and they say the debate is obscuring the most important part, which is informing the public about key updates in science and medicine.Studies on the safety of vaccines against shingles and Covid were reportedly quashed before publication by officials at the US Food and Drug Administration (FDA). The news follows the hasty halt on publication of a study on the effectiveness of Covid boosters by the top acting official at the US Centers for Disease Control and Prevention (CDC), and research terminated or never approved in the first place because of keywords such as “hesitancy” and “misinformation” at the National Institutes of Health (NIH).

Serious side effects from vaccines were rare, scientists found in studies funded by US taxpayer moneyThe US Food and Drug Administration has blocked the publication of several studies that found Covid-19 and shingles vaccines to be safe, according to a spokesperson from the Department of Health and Human Services.Agency scientists conducted the studies by analyzing millions of patient records and found that serious side effects from the vaccines were rare, the spokesperson confirmed. The studies – funded by taxpayer money and costing several million dollars – included research examining the safety of Covid-19 vaccines in 2023 and 2024. Continue reading...

• The Trump administration filed an appeal Wednesday evening against a Massachusetts federal judge's March 16 ruling that blocked Health Secretary Robert F. Kennedy Jr.'s overhaul of the nation's childhood vaccine schedule. • Judge Brian Murphy had ruled that Kennedy replaced the CDC's vaccine advisory committee "unlawfully" and placed any decisions made by the committee on hold. • The appeal signals the administration's intention to proceed with restructuring the vaccine advisory process despite legal challenges to its authority.

• Senators Ron Johnson and Robert F. Kennedy Jr. labeled federal handling of COVID origins and vaccine deaths a 'major scandal' with alleged coverups. • They cited new evidence pointing to lab leaks and unreported adverse events. • The claims fuel demands for investigations as public trust in health agencies erodes.

• Connecticut Governor Ned Lamont signed HB 5044 into law on April 28, 2026, expanding the state health commissioner's authority to issue vaccine recommendations independent of federal guidance. • The bill includes provisions clarifying the state's Religious Freedom Restoration Act (RFRA), which had sparked significant controversy during legislative debates. • The law also prevents insurance companies from penalizing clinicians who treat patients declining vaccines, protecting physician practice autonomy.

• A recent study demonstrates that an updated vaccine formulation reduced emergency department visits and hospitalizations among healthy adults by approximately 50 percent during the past season. • This significant efficacy improvement represents a major advancement in vaccine development and public health protection strategies. • The findings contribute to the evolving landscape of U.S. vaccine policy, as documented in CIDRAP's latest state of vaccine policy report from April 28, 2026.

• A multiyear international campaign is underway to repair damage to childhood immunization efforts caused by the COVID-19 pandemic. • The initiative focuses on restoring vaccination rates that declined during the pandemic period across multiple countries. • Public health experts view this effort as critical to preventing resurgence of vaccine-preventable diseases in vulnerable pediatric populations.

• Health Secretary Robert F. Kennedy Jr., a prominent anti-vaccine voice, praised President Trump's nomination of Dr. Erica Schwartz as CDC Director and expressed his intention to work with her to restore the agency's mission. • Kennedy's public endorsement of the pro-vaccine nominee marked a sharp reversal from his previously hard-line stance on CDC leadership and sparked significant backlash among MAHA (Make America Healthy Again) loyalists online. • The shift comes amid congressional scrutiny of Kennedy's conflicting rhetoric on measles vaccination safety during a Thursday hearing, as measles outbreaks rise across the U.S.

Several shots – including flu and Covid – lost their CDC recommendations under overhauls from the White HouseSeveral shots lost their recommendation from the US Centers for Disease Control and Prevention (CDC) after a judge’s stay against changes wrought by the Trump administration – which may affect access to the shots in some states. And no new vaccine recommendations may be made as long as the vaccines committee is halted.Access to existing vaccines – and the future development of new vaccines – has been increasingly called into question under the second Trump administration, as the now-halted Advisory Committee on Immunization Practices (ACIP) made controversial recommendations and health officials made unilateral changes to routine vaccines, with long-term and global implications.

• A Fred Hutch Cancer Center graduate student presented over 25,000 measurements of influenza-fighting antibodies to WHO scientists via videoconference last fall. • The dataset, published in Virus Evolution, offers near real-time tracking of human immune responses to current flu strains, improving seasonal vaccine composition. • This method addresses gaps in traditional surveillance, potentially enhancing vaccine effectiveness against evolving viruses.

Study that reportedly found reduction in ER visits and hospitalizations being reviewed by Jay BhattacharyaA Trump administration appointee has delayed publication of a Centers for Disease Control and Prevention (CDC) report that shows benefits related to the Covid vaccine, leading to concerns that the administration is engaging in behind-the-scenes tactics to undermine vaccines.Research by CDC scientists found that the Covid vaccine cut the likelihood of emergency room visits and hospitalizations for healthy adults last winter by about half, according to reporting from the Washington Post. The acting CDC director, Jay Bhattacharya, reportedly delayed the report’s publication due to concerns surrounding the research’s methodology. Continue reading...

• The FDA granted approval on April 7, 2026, to Moderna's mRESVIA vaccine, an mRNA-based shot targeting respiratory syncytial virus (RSV) for adults aged 60 and older. • Clinical trials showed 83.7% efficacy against RSV lower respiratory tract disease in the first season, with data from over 37,000 participants across 22 countries including US sites. • This marks the second mRNA RSV vaccine approved after GSK's Arexvy, aiming to reduce 140,000-160,000 annual US hospitalizations among seniors; CDC review expected soon.

Elections seem top-of-mind for the Maha movement as key polling indicates anti-vaccine views are a liabilityUS health officials appear to be shying away from voicing negative views of vaccines in public as November’s midterm elections loom and key polling indicates anti-vaccine views are a liability.Health officials have made unprecedented changes to routine vaccine recommendations in the past year – slashing one-third of the US childhood schedule, including the recommendation for hepatitis B immunization at birth. But even before a federal judge essentially invalidated these moves, officials haven’t championed their dramatic changes after Donald Trump’s pollsters recommended veering away from anti-vaccine ideology ahead of the midterms.
