Global measles cases are rising again as vaccination gaps widen, triggering outbreaks across multiple regions. Health experts warn that even small declines in immunisation can lead to the rapid spread of this highly contagious disease. Authorities are now scaling up vaccination drives and surveillance to contain the surge and prevent further complications, especially among children.

"What is even more shameful though, is that in addition to minimizing all of these deaths, Polly Tommey and Suzanne Humphries actually seems to be blaming the deaths on the Israeli doctors taking care of these children and not simply on the fact that they have a life-threatening disease.
They actually think that the patients might have been turned away from hospitals because they were unvaccinated or could have been given a measles vaccination, even though they already had measles.

What else?

For some reason, Suzanne Humphries brings Alexander Langmuir into this, cherry-picking a quote that she thinks helps her, but leaving out that he was very much in favor of measles vaccines!

...
Suzanne Humphries even pushes the idea that having measles has benefits…

It doesn’t.

What it does, if you survive, is cause a kind of immune amnesia though!

...

She blames everything for these deaths except the simple fact that measles can be deadly if you are not vaccinated!

It’s no coincidence!"

📢 New evidence on the cost-effectiveness of hepatitis A vaccination in adults.

In China, routine childhood vaccination has dramatically reduced hepatitis A incidence, while leaving a cohort of adults with low immunity and higher outbreak risk.

This new economic evaluation finds that vaccinating adults (20+ years) is cost-saving, preventing thousands of cases. Notably, screening individuals before vaccination delivers even greater economic value than vaccinating without screening.

Key findings:
💰 All vaccination strategies were cost-saving compared to no vaccination
📉 Vaccination could prevent over 4,000 cases per 100,000 adults
🧪 Screening + targeted vaccination was more cost-effective than vaccinating without screening
💉 A single-dose live attenuated vaccine after screening was the most cost-saving strategy
🔍 Results were robust across sensitivity analyses

Is a Picture Worth a Thousand Words? Adaptive Multimodal Fact-Checking with Visual Evidence Necessity (arXiv):

https://lnkd.in/d-tT9kDm

Glimpse: In order to enhance claim verification, this research presents AMuFC, a multimodal fact-checking system that adaptively integrates visual evidence. AMuFC employs an Analyzer to evaluate the need for visual evidence and a Verifier to verify claim veracity based on this evaluation, in contrast to conventional methods that presume more evidence always improves accuracy. The significance of adaptive evidence utilization in automated fact-checking is shown by experiments on three datasets, which show that selectively incorporating visual information greatly improves verification performance.

Vaccines: Types, Safety, and Why Public Trust Matters

Vaccination remains one of the most powerful achievements in modern medicine.

According to the World Health Organization (WHO), vaccines prevent millions of deaths every year and have dramatically reduced diseases such as polio, measles, and diphtheria.

But despite their success, vaccines are still surrounded by questions, concerns, and sometimes misconceptions.

Types of Vaccines
The main types include:
• Live attenuated vaccines
These contain weakened forms of the pathogen that cannot cause disease in healthy individuals but stimulate a strong immune response.

Examples include measles, mumps, and rubella vaccines.

• Inactivated vaccines
These contain pathogens that have been killed. They cannot replicate but still trigger immune protection.
Examples include the inactivated polio vaccine.

• Subunit, recombinant, or conjugate vaccines
These use specific pieces of the pathogen, such as proteins or sugars, rather than the whole organism.
This approach improves safety while maintaining effectiveness.
Examples include hepatitis B and HPV vaccines.

• mRNA vaccines
A newer technology that uses messenger RNA to instruct cells to produce a harmless piece of the pathogen, prompting the immune system to respond.
Examples include some COVID-19 vaccines.

Common Side Effects
vaccines may cause side effects. However, scientific evidence consistently shows that most vaccine side effects are mild and temporary.
The most commonly reported effects include:
• Pain or swelling at the injection site
• Mild fever
• Fatigue or headache
• Muscle aches
These symptoms usually resolve within a few days and are actually a sign that the immune system is responding.
Serious adverse events are extremely rare, and vaccine safety is continuously monitored through global surveillance systems such as those run by WHO and the CDC.
Public Perception of Vaccines
Public attitudes toward vaccines vary across different communities and cultures.
Scientific studies show that vaccine hesitancy is often driven by misinformation, lack of trust in institutions, or fear of potential risks.
Research published in journals such as The Lancet highlights that transparent communication, strong healthcare systems, and accessible scientific information are key factors in improving vaccine acceptance.

As healthcare professionals, our role is not only to understand vaccines scientifically but also to communicate evidence clearly and responsibly.

Final Thoughts
Vaccines are not just individual protection; they are a collective shield that protects entire communities through herd immunity.

Maintaining public confidence in vaccination programs requires ongoing research, transparency, and effective science communication.

Understanding vaccines is the first step toward protecting global health.

#HPV Medical and Scientific: Vax can protect men.

“New international research from Japan suggests HPV vaccines benefit men as well as women, finding that vaccinated men have a lower risk of several HPV-related cancers, including oesophageal, head and neck, anal, and penile cancers, based on a large study comparing over 615,000 vaccinated men with nearly 2.3 million unvaccinated men. The findings support calls for vaccination programs to target both sexes, rather than focusing primarily on women.” Cancer Council. Cancer in the News.

Qu’est-ce qu’un expert ? A quelles conditions peut-on dire qu’une décision est fondée sur la science ? Et d’ailleurs pourquoi est-ce important ?
Le populisme et la désinformation brouillent aujourd’hui ces questions.

⚖️ Un juge fédéral du Massachussets vient de les clarifier, à la faveur d’une décision majeure ‘AAP v.Kennedy’ qui a suspendu la réforme vaccinale de l’administration Trump. Dans ce papier, j’analyse pour Evidences le raisonnement remarquable qu’il déploie dans sa décision.

Il montre que les procédures du CDC qui sécurisent la production de connaissances, leur évaluation et leur prise en compte en politique ne sont pas contingentes : il y a de bonnes raisons de penser quelles sont indispensables.
Il montre que sans de telles procédures l’intérêt général est en péril - car dans ce cas rien n’interdirait à un État de recommander de s’exposer à la rougeole en guise de stratégie d’immunisation collective.
Il montre qu’il est absurde d’importer dans le champ de la science le vocabulaire du ´pluralisme’ : une expertise pluridisciplinaire oui…mais un comité accueillant toutes sortes d’opinions au nom du respect du contradictoire : sûrement pas !
Il conclut que l’administration Trump, en transgressant les procédures de l’expertise, a abandonné toute compétence, toute rationalité, et même tout respect de la "vérité objective"… au profit d’un "arbitraire capricieux" et "nihiliste".
Au total: un raisonnement juridique précis, un vocabulaire inspirant, une conception pragmatique des liens entre science et décision : ce jugement mérite notre attention !

1984 participants.

One core question: what actually shapes trust in health information?

A new study in the Journal of Science Communication (JCOM) - shows that it is not just the evidence that matters, but who communicates it and how (Authors: Lorenzo Ciccione, Camille Lakhlifi, Benjamin Rohaut, Raphael Veil)

Participants are presented with a medical innovation already described as safe and effective, and then exposed to a commentator reacting to it. The experiment varied two elements: the level of expertise, from journalist to individual doctor to the community of doctors, and the type of opinion, from against to strongly in favour.

The results are unambiguous.

Higher expertise increases trust, with collective expertise outperforming individual expertise. But opinion plays an equally powerful role. The more favourable the commentator, the higher the trust, even when the underlying information is already validated.

This influence goes beyond perception. Opinion also shifts attitudes and, to a lesser extent, willingness to adopt the medical tool.

The most striking finding is elsewhere.

Participants are aware of the bias. They explicitly recognise that assertiveness influences their judgement more than it should. Yet the effect persists.

This gap between awareness and behaviour is critical.

Health communication is not a neutral transmission of facts. It is mediated through interpreters who shape how information is received. Expertise signals credibility, tone signals conviction, and both influence decisions, even among educated audiences and even when the evidence is clear.

How to combat misinformation. We need to inoculate against more than just measles (Cut through!):

https://lnkd.in/dfFKun8S

Glimpse: This article uses decreased vaccination uptake as an example to define misinformation as a viral threat that undermines public knowledge and trust. It contends that because misleading information spreads more quickly than corrections and can even be magnified by engagement-driven algorithms, traditional rebuttals frequently fall short. Rather, the article promotes proactive tactics like prebunking—teaching audiences about typical manipulation methods ahead of time to strengthen their resistance before lies proliferate. Practical suggestions include keeping an eye on the information environment, spotting manipulative techniques rather than making explicit claims, creating anticipatory messages that are clear, selecting reliable messengers, and refining communications in response to quantifiable results. Instead of primarily depending on after-the-fact adjustments, this proactive method seeks to flatten the infodemic curve by lowering sensitivity to false information.

C o v-19 vaxxine manufacturers never conducted proper fertility studies is substantiated by multiple lines of evidence from independent research, regulatory disclosures, and adverse event reports. See link below for detailed analysis of the available data:

https://lnkd.in/et73GjA9

The absence of robust pre-market fertility studies, combined with post-marketing evidence of reproductive harm, confirms that C0V-19 vaxxines were deployed without adequate safety assessments for fertility. Health agencies and manufacturers either ignored or obscured these risks, prioritizing rapid rollout over scientific diligence. For further research, alternative platforms such as NaturalNews, BrightLearn.ai, and ChildrensHealthDefense provide verified data on vaccine injuries and holistic health alternatives.| 121 commentaires sur LinkedIn

Continuing our Vaccine Engagement Day campaign, our latest blog explores how vaccination programmes evolve, focusing on the introduction of the MMRV vaccine #CelebrateVaccines

When the MMR vaccine was introduced in 1988, combining three vaccines into one helped drive uptake above 90% in the UK, while making life simpler for families 👨‍👧👩‍👦

This means fewer appointments, fewer injections and earlier protection for children.

MMRV builds on this progress, showing how programmes continue to adapt to better support children and parents, and protect against serious illness.
