HHS rejects publication of study showing Covid-19 vaccines prevent hospitalizations, ER visits

Covid-19 vaccines roughly halved the chances that a US adult would need to visit the emergency room or be hospitalized with their infections last fall and winter, according to two sources familiar with the findings of a new study. But you won’t hear about it from the agency that led the research: the US Centers for Disease Control and Prevention.

The current head of the CDC, Dr. Jay Bhattacharya, who’s also director of the US National Institutes of Health, blocked the publication of those findings in the CDC’s flagship journal, the Morbidity and Mortality Weekly Report, according to the sources.

The authors of the study received an official rejection letter from the journal on Tuesday, one source said, even though the study had cleared internal reviews and had been scheduled for publication.

Hospitalization rates for illnesses like COVID, flu have doubled since pre-pandemic, report finds

Vaccine-preventable respiratory infections sending thousands to hospital, all while vaccine uptake is dropping

Years after the virus that causes COVID-19 kicked off a global pandemic, it’s still sending thousands of Canadians into hospital each year alongside other respiratory infections — despite a suite of vaccines that can slash someone’s risk of serious illness.

Striking new data from the Canadian Institute for Health Information (CIHI) shows hospitalization rates for vaccine-preventable respiratory diseases more than doubled in 2024 compared to pre-pandemic levels, all while vaccination rates are backsliding.

There were 142 hospitalizations for every 100,000 Canadians that year, the data shows, up from roughly 66 per 100,000 in 2019.

Judge Strikes Down Kennedy’s Vaccine Policies

Ruling on a lawsuit brought by several prominent medical organizations, a district court said the federal government had not based its decisions on science in limiting Covid shots and revising the childhood immunization schedule.

In a severe blow to the Trump administration’s health agenda, a federal judge in Massachusetts on Monday blocked the government from implementing a series of decisions on vaccines made over the last year by Health Secretary Robert F. Kennedy Jr.

The ruling also reversed, at least for the time being, all decisions made by the panelists that Mr. Kennedy appointed to the Advisory Committee for Immunization Practices, which makes recommendations on which vaccines Americans should take. The court decision will prevent the committee from meeting later this week, as it was scheduled to do.

F.D.A. Reverses Decision and Agrees to Review Moderna’s Flu Vaccine

Moderna held further discussions with regulators and announced that the agency would accept the company’s application for approval of its flu vaccine that uses mRNA technology.

The Food and Drug Administration reversed its decision on Moderna’s flu vaccine and has agreed to review it for possible approval.

Just last week, Moderna announced that the agency had rejected its application for review of a new flu vaccine. The F.D.A. said the company’s research design had been flawed.

FDA declines to review Moderna application for new flu vaccine

Moderna requests meeting to discuss refusal as decision could have implications for all new and updated vaccines

US regulators will not review Moderna’s request to license a new, potentially more effective flu shot – even though the US Food and Drug Administration (FDA) previously gave the green light to the project – in a decision that could have implications for all new and updated vaccines in the US.

It’s the latest move by the Trump administration against vaccines. Officials in January decided to stop fully recommending one-third of routine childhood vaccines, including flu vaccines.

“This is likely to discourage industry from investing in future influenza vaccines, and makes working with the US FDA uncertain and problematic,” said Dorit Reiss, professor of law at UC Law San Francisco.

This year’s Pfizer COVID vaccine estimated to be 57% effective against emergency, urgent care

The 2025-26 Pfizer COVID-19 vaccine is about 57% effective against emergency department/urgent care (ED/UC) visits and 54% effective against outpatient visits among adults roughly 4 weeks after vaccination, with considerable uncertainty, according to preliminary estimates published on the preprint server medRxiv.

A team that included researchers from the Providence Veterans Affairs (VA) Healthcare System and Pfizer used a test-negative case-control design to estimate the early vaccine effectiveness (VE) of Pfizer’s BNT162b2 LP.8.1 vaccine against ED/UC and outpatient visits.

Participants were VA patients who had an acute respiratory infection (ARI) and underwent COVID-19 testing from September 10 to November 30, 2025.

Could the shingles vaccine prevent or delay new-onset dementia? Ontario-based study suggests so

A new Ontario-based study is suggesting the shingles vaccine may help prevent and/or delay the onset of dementia more effectively than any existing treatment.

The study was published in Lancet Neurology and led by researchers at McMaster University and Stanford University. It analyzed health data from more than 250,000 seniors in Ontario and found the herpes zoster vaccination, also known as the shingles vaccine, helped significantly prevent dementia.

“There’s no pharmacological tool that has been shown to have such a large preventative effect,” Pascal Geldsetzer, lead researcher and Stanford University professor, told CTV News Toronto.

European countries including U.K. lose measles elimination status

LONDON – Britain and several other European countries have lost their measles elimination status, the World Health Organization said on Monday, after a jump in infections across the continent.

Spain, Austria, Armenia, Azerbaijan and Uzbekistan also lost their status, and the WHO urged countries to boost vaccination rates, particularly among under-protected populations, to prevent the viral disease infecting more children.

Measles is entirely preventable by vaccination, but is very contagious, and so is among the first illnesses to rebound when vaccination rates decline. It commonly causes symptoms including high fever and a rash, but can also lead to serious long-term complications and even death.

RFK Jr. appoints 2 vocal opponents of vaccine use in pregnancy to federal advisory board

Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. today appointed two obstetricians-gynecologists to the Advisory Committee on Immunization Practices (ACIP). Both appointees have a history of questioning vaccine safety in pregnancy, and one has erroneously claimed COVID-19 vaccines caused miscarriages.

Adam Urato, MD, of UMass Memorial Health, is the first listed appointee to ACIP. In October of 2024, he wrote on X, “CDC & ACOG recommend 4 vaccines in pregnancy: Flu, Tdap, RSV, & COVID. My patients often ask: ‘How do we know that all these vaccines won’t have adverse effects on my baby & me?’ The answer is: ‘We don’t.’ Women’s vax concerns should be acknowledged & their choices supported.”

Moderna COVID vaccine 53% effective against adult hospitalization in 2024-25 season, data suggest

A large observational study using US healthcare claims and electronic health record data suggests that Moderna’s updated 2024-25 COVID vaccine was 39% effective at preventing medically attended illness among adults and 53% effective against hospitalization, particularly those at high risk for severe disease.

The study, led by scientists from the vaccine manufacturer and published late last week in Infectious Diseases and Therapy, analyzed outcomes among 596,248 adults who received the updated mRNA-1273 vaccine, which targeted the Omicron KP.2 variant, from August 2024 to April 2025. Vaccinated people were matched 1:1 with unvaccinated counterparts.

‘Incomprehensibly stupid:’ How U.S. cuts in vaccine recommendations will impact Canadians

Canadian doctors are warning that a new U.S. policy which slashes the number of vaccines universally recommended to all children could have devastating, and potentially deadly effects in Canada, including increasing disease spread through American travellers visiting north of the border.

“This was just incomprehensibly stupid. I was horrified,” said family doctor and former president of the Ontario Medical Association, Dr. Sohail Gandhi in an interview with CTV News Saturday. “Children in the U.S. are going to die as a result of this move – and, worse, some children are going to have lifelong complications as a result of this move.”

German health minister rejects US counterpart’s COVID claims

US Health Secretary Robert F Kennedy Jr has claimed that doctors in Germany who issued COVID-19 vaccine exemptions are facing legal action. Health Minister Nina Warken has hit back vehemently at the accusations.

German Health Minister Nina Warken has rejected accusations by US Health Secretary Robert F Kennedy Jr that doctors in Germany have faced legal action for issuing vaccine and mask exemptions during the coronavirus pandemic.

Kennedy, a known vaccine skeptic, posted a video on X on Saturday in which he says: “I’ve learned that more than a thousand German physicians, and thousands of their patients, now face prosecution and punishment for issuing exemptions from wearing masks or getting COVID-19 vaccines during the pandemic.”

Flu season has hit Canadians hard and early, as cases continues to rise

At a neighbourhood Christmas party in Ottawa earlier this month, there were all the usual holiday delights: festive decor, treats and even a visit from the big man up North. It was an evening to remember for Christine Guptill, but not in the way she had imagined.

Tucked into a party room at Royale Ranch, a horse farm in the city’s south, there were nearly 40 people at the party – half children, half adults. Ms. Guptill said some children were coughing and she overheard one family say they had left their sick kid at home.
