Trust isn't something you build. It's a reading on a dial, produced by six drivers that have nothing to do with the word "trust" itself: competence, benevolence, integrity, predictability, transparency, and reciprocal vulnerability.

None of them can be targeted directly. All of them can be built as procedures long before the emergency starts.

Each year, the World Health Organization and UNICEF release the clearest picture we have of how many people are reached with vaccines. 
 
This year, the data shows that child immunization coverage inched forward in 2025 compared to 2024, with 85% of children worldwide receiving their basic childhood immunizations. Fifty years ago, that figure was just 5%. 
 
HPV vaccine access also continues to improve, with 33% of girls receiving the vaccine last year, up from 31% in 2024, driven by 15 new country introductions. 
 
That progress reflects decades of commitment: countries strengthening their health systems, partners sustaining investment in programs like Gavi, the Vaccine Alliance, and health workers reaching children and their families. 
 
But the data also shows where gaps remain. 13.5 million children have still not received a single vaccine. In 2025, 57 countries reported large or disruptive measles outbreaks. This means it’s more important than ever to ensure every child can access lifesaving vaccines. 
 
We've come a long way, but the job isn't finished. Vaccines work, and our task now is to maintain that momentum so every child, no matter where they live, has the opportunity to grow up healthy and reach their full potential. 

Je suis scientifique et ce que je vais dire ne va pas plaire à tout le monde : pour lutter contre la désinformation, nous n'avons pas besoin de plus de faits scientifiques.

Quand une fake news se propage, je vois toujours les mêmes réflexes :
- publier une étude,
- montrer un graphique,
- ajouter des chiffres,
- puis d'autres chiffres,
- puis encore d'autres chiffres…

Comme si le problème était un manque de données.

Entre Google, ChatGPT, les émissions santé à la TV, les réseaux sociaux et tonton Gérard, il y a toujours quelqu’un pour répondre à nos questions en citant “une étude”.

Le problème n'est pas (toujours) l'absence de faits, le problème est que les faits voyagent mal.

Une étude scientifique est rarement conçue pour captiver l'attention du grand public.
Une histoire, si. Or, les désinformateurs sont très bons pour raconter des histoires.

Face à ça, nous n’avons pas seulement besoin de produire davantage de connaissances.
Nous devons aussi créer davantage de ponts entre ces connaissances et le grand public.

Parce qu'aujourd'hui, la bataille ne se joue pas uniquement sur les données trouvées.
Elle se joue aussi sur notre capacité à les rendre accessibles.

Et sur ce terrain-là, nous avons besoin de plus de vulgarisateurs, d’experts qui viennent expliquer, simplement, sans jargon (mais rigoureusement !) ce qu’il se passe, ce qu’on sait et ce qu’on ne sait pas encore au grand public.

C’est un vrai enjeu de santé publique, qui doit être considéré par les scientifiques comme par les politiques 🙏

Media literacy is now just as important as learning to read and write, lawmaker says (EUPerspectives):

https://lnkd.in/dpRuxfMt

Glimpse: As important as learning to read and write, media literacy is today regarded as a fundamental democratic ability. The article makes the case that societies must treat media literacy as a fundamental skill rather than an optional add-on due to the rapid changes in the information ecosystem, including AI-generated content, algorithmic amplification, dwindling trust in institutions, and increasingly hazy boundaries between journalism, opinion, and manipulation. Three priorities are highlighted by educators and politicians throughout Europe: enhancing critical thinking abilities, educating individuals to identify false information and synthetic media, and including media literacy courses at all educational levels. The article emphasizes that media literacy allows people to actively and intelligently participate in democratic life in addition to safeguarding them against damage. Societies run the risk of increasing polarization, becoming more susceptible to manipulation, and losing public trust if media literacy is not widely practiced.

"Rumours are part of society. The issue is, how do we, from a public health perspective, deal with it?"

This quote from Dr Tina D Purnat's talk at the 14th IFPH at the University of Manchester took me right back to why we started our project last year.

As a researcher in a referral oncology hospital, I kept encountering rumours among cancer patients about their medications and when I traced where many of these originated, I found they were spreading through the online patient groups they'd formed with each other.

But instead of treating this as simply a "misinformation problem" to correct, my team and I decided to use it as an opportunity: to actually study the nature of these groups and the real needs driving them. Things like:

⭕ Concerns patients have about their treatment
⭕ Confusion when choosing between different treatment options
⭕ Lack of information on how to manage medication side effects

And countless other questions that, once understood, can help us improve the quality of care we offer cancer patients in Iran.

The novelty of our work doesn't stop there; we're also using LLMs, combined with clinician input and patient validation, to help make sense of this at scale.
Grateful to my team at the Clinical Research Development Center of Amir Oncology Hospital for this work, especially to Dr Elahe Meftah.

🎉 I'm honoured to have had the chance to present a small part of this project as a poster at this festival this week. The abstract is now available in the European Journal of Public Health:

A year ago today, a study out of Denmark was published that the media hailed as conclusively proving that aluminum-containing vaccines are not associated with chronic childhood illnesses including allergies, autoimmune diseases, and neurodevelopmental disorders.

But the study was systematically biased in favor of the null hypothesis, as illuminated by its own key data IMPLAUSIBLY showing a protective effect of aluminum on childhood development:

🔎📰 Misinformation on vaccines (aka NON-SPECIFIC VACCINE EFFECTS (NSE) this time on the diphteria-tetanus-pertussis vaccine) playing out - again!
It’s a disgrace - to be witnessing this in 2026😳

#NSEvaccNeverReplicated

"Although I discuss clinical research in the form of case-control, cohort, and randomized controlled studies, I have always preferred data from meta-analyses and systematic reviews since they provide the most robust clinical evidence.

But the most important point to make is that placebo controlled randomized clinical trials are not the only way to determine safety and effectiveness of vaccines. There are larger, statistically powerful methods that can tell us how any drug, including vaccines, are working.

Anti-vaccine activists love to cherry-pick research that seems to support (but rarely does) their desire to say “ah-ha” about vaccines. Unfortunately for them, research is complicated and there are lots of different types of studies that indicate vaccines are very safe and very effective."

The sad death of Senator Lindsey Graham from an aortic dissection may offer an important opportunity to learn more about vascular disease in the post-pandemic period.

One of the major gaps in current research is the limited number of detailed autopsy studies examining vascular tissue in people exposed to COVID reinfection, vaccination, or both. Without careful histology, it is difficult to know whether inflammatory patterns are present in the aortic wall, particularly around the vasa vasorum, the small vessels that supply the outer layers of the aorta.

This is an area I have followed closely as inflammation affecting the vasa vasorum could impair blood supply to the aortic media, weaken smooth muscle and elastic tissue, and potentially increase vulnerability to aneurysm or dissection in susceptible individuals. It may also contribute to broader changes in arterial stiffness and pulse-wave behaviour.

This does not establish that a reinfection or vaccination immune priming caused Lindsey Graham’s dissection. It does, however, justify asking whether a high-profile case such as this will receive the depth of pathological examination needed to exclude or identify inflammatory aortitis, medial degeneration, microvascular injury, or other relevant disease processes.

I hope detailed histological analysis of the aorta is undertaken and, where ethically and legally possible, the findings are shared with the scientific community.

One case cannot define a population trend, but carefully investigated cases can reveal the patterns that larger studies should then test.

Propos recueillis par Jean-Paul Krivine (31 janvier 2026) SPS. Pour l’élaboration de ce rapport, vous avez auditionné près de 300 personnes : (…)

It’s not informed consent when you don’t inform.

We believe people don’t remember statistics. They remember stories. They don’t act because information exists—they act because information connects. Our role is to transform evidence into clarity, clarity into confidence, and confidence into meaningful conversations that improve health.

A bill with bipartisan support was just introduced, and we are very happy about it. It would modernize the program that compensates people in the rare cases when a vaccine causes a serious injury, and it would finally bring COVID-19 vaccine claims into that system.

A bit about how this works. The Vaccine Injury Compensation Program (VICP) has been around since 1986. It's a no-fault system, which means people don't have to sue a manufacturer or prove negligence to be compensated. It runs on a small excise tax on vaccines rather than taxpayer dollars, and it uses an "injury table" that lists injuries known to be associated with certain vaccines. If someone experiences one of those recognized injuries in the expected timeframe, it's presumed connected, and they don't have to prove causation from scratch. Other claims can still be considered, they just require more evidence.

If you're wondering why COVID-19 wasn't already included, it comes down to timing. When the vaccines first rolled out under emergency use authorization, injury claims were routed into a separate, more limited program called the Countermeasures Injury Compensation Program (CICP), which was built for public health emergencies. That program doesn't allow you to appeal a decision, doesn't cover pain and suffering, and has a large backlog of claims that have been sitting without a decision for years. Even after the COVID-19 vaccines received full FDA approval and were added to the immunization schedule, those claims were never moved into the stronger, fairer VICP that covers other routine vaccines. This bill fixes that.

Our support for vaccines has always been about public health, not pharma companies. Vaccines save millions of lives. In the rare instances where someone is injured, we feel strongly that they deserve a fair, timely, and compassionate path to compensation. Standing up for those people and standing up for vaccines are the same thing, and it's encouraging to see both parties recognize that.

We will share updates as we have them.

People believing this misinformation should be referred for psychiatric evaluation. Such is a lie… And McCullough Foundation posts such shows how desperate they are for views for nothing…

New South Wales health authorities have hailed a vaccination program that has nearly halved hospitalisations for a potentially deadly respiratory virus among newborn babies a "fantastic" success, as the winter illness peak fast approaches.

How long does misinformation from McCullough Foundation stay on LinkedIn ? Too long. Now regarding the spike protein staying in one’s blood ? Well, not controlling for COVID infections and long COVID shows how terrible these claims are…

"Every time I share information about the MMR vaccine, the same question comes back: Why do you care so much about a disease with a case-fatality rate of one or two in a thousand?

My answer comes in two parts.

The first is simple. Even one preventable death is one too many, especially when the thing standing between a person and that death carries an exceedingly small risk of its own. We're weighing a vanishingly rare serious vaccine reaction against a disease that can kill, and that can do serious, lasting harm along the way.

The second part is the one that the "case-fatality rate" question doesn't account for. It treats measles as a coin flip. Heads you live, tails you die, as if there weren't an entire world of possibilities in between. There is, and that in-between is where measles does some of its most underappreciated damage.

Start with immune amnesia. When I talk to my immunology buddies about this, their eyes get wide. Measles doesn't just make you miserable for a week or two. It infects immune cells, including the long-lived memory cells your body uses to recognize infections it has already beaten, and it wipes out part of that hard-won memory.

A 2019 study in Science found measles erased anywhere from 11% to 73% of children's existing antibody repertoire, and even kids with mild cases lost about 20% on average. Your body can be left having to relearn defenses against infections it had already beaten, and it can take two to three years to rebuild what measles took. A statistical analysis of childhood mortality data suggests that, before the vaccine, this immune amnesia may account for as much as half of all childhood deaths from infectious disease,...


Measles does obvious harm in the moment, too. About one in five unvaccinated people who catch measles in the United States end up hospitalized, often with pneumonia or dehydration. Utah's ongoing outbreak has hospitalized 8% of its cases so far. In South Carolina, one hospital system that treated the outbreak there saw 16% of its confirmed patients admitted, two with encephalitis, or brain swelling.

In young children, measles can also cause swelling of the upper airway to the point of obstruction. Conducted during a 2025 outbreak, a Pediatrics study found this kind of stridor in about one in eight children with measles. Nearly 90% were hospitalized, and some needed intensive care. Not one of them died. Roughly one in 1,000 develops acute encephalitis, which can leave children deaf or with permanent intellectual disability even if they pull through.

SSPE, subacute sclerosing panencephalitis, is rare. But it's a nightmare. Years after what looked like a full recovery, the measles virus can reactivate in the brain and begin a slow, relentless demolition: cognitive decline, seizures, loss of motor control, then death. There's no cure, and it is almost always fatal. "

My latest Center for Infectious Disease Research and Policy (CIDRAP) op-ed is up, and it's about something that really grinds my gears... the idea that death is the only bad thing that can happen if you get measles.

We hear this all the time: "....but the case fatality rate is only one or two in a thousand," as if measles is a coin flip, heads you live, tails you die, nothing in between.

The in-between does a lot of damage. For one, immune amnesia that wipes out part of your immune memory and takes years to rebuild. There's also hospitalizations, airway swelling that lands little kids in the ICU, encephalitis, and SSPE, which can surface years after recovery and is almost always fatal. None of those things show up in a case fatality rate.

The MMR shot protects against all of it, not just the worst case. Read more in the full op-ed over at CIDRAP: https://lnkd.in/ed3YgeBQ

Did you know that with two doses of the MMR vaccine, children can still be infected with measles virus and spread it to others – even with mild or no symptoms of their own?

Andersson et al. claimed to show aluminum-adjuvanted vaccines do not cause chronic illnesses. Crépeaux et al. reveal the problems with that study.

Anxiety about needles is common in children and adults. For some, anxiety can lead them to delay or avoid vaccination, even if they know it’s important. ImmunizeOrg’s president and CEO, Dr. Kelly L. Moore offers practical advice for healthcare professionals and the public in the Improving the Vaccination Experience Video Series. Each video is about 4 minutes long.
