🎯 Le cas du Haut-Katanga illustre parfaitement cette réalité : la couverture vaccinale est passée de 44,9 % (2022) à 33 % (2025), avec 18,5 % d’enfants zéro dose, dans un contexte de circulation persistante du poliovirus dérivé de type 2 et d’épisodes répétés de rougeole.
Face à cette situation, le PNDS-PS 2024–2030 et la Stratégie Nationale de Vaccination 2025–2030 placent la vaccination parmi les priorités stratégiques nationales.
🔍 C’est dans ce contexte que s’inscrit mon travail de recherche, encore en phase de protocole :
➡️ identifier les goulots d’étranglement de la vaccination de routine chez les enfants de 0–23 mois, afin de proposer des solutions opérationnelles adaptées au contexte réel des zones de santé.
En accord avec l’OMS (2014) (16,17), et l’UNICEF (61), nous sommes convaincus que l’identification des goulots d’étranglements de la couverture vaccinale de routine chez les enfants de 0-23 mois dans son contexte contribuerait à l’augmentation de la couverture vaccinale.

Je partagerai prochainement les avancées de ce travail et les premières analyses.

For years, RFK Jr. has been an ardent vaccine skeptic who has also repeatedly claimed that vaccines cause autism. But that particular myth didn't start with him.

I have just learned that when they found out CDC's search tool was down, The Immunization Action Coalition put together a page with various search tools for vaccines, with different categories - could be useful to people:

We have seen at the Children's Health Defense symposium what a true cartel is. An anti-vaccine cartel of doctors having lost their license due to the lies they were and are still pushing, of lawyers denying science in pushing forth lawsuits without merits, and of poor parents being feed lies. This is no longer a fringe group. It is now a cancer that has infiltrated the administration. It is a business. And is now a religion of conspiracy….

Yuck! I need to bathe after reading this! See comments... | 12 comments on LinkedIn

📄 A new study explores the relationship between immunization budgets and vaccine coverage across 9 antigens in 19 low- and lower-middle-income countries analyzed data from UNICEF’s newly released Global Immunization Budget Database for 2021-2024.

📈 A one percentage point increase in the immunization budget was associated with a 0.42% increase in DTP1 coverage growth rate when controlling the years. Other antigens, including DTP3, BCG, MCV1, POL3, IPV1, and PCV3, also showed positive but non-significant trends.

💡The author, Hao-Kai TSENG, highlights that the Global Immunization Budget Database is a breakthrough in immunization economics, leveraging AI to extract and categorize scattered line items from national budget documents, and providing an early outlook into governmental priorities.

Why do vaccines seem to work better in rich countries than in poor ones?

Our new Lancet Microbe paper from the HypoVax Global consortium shows that this inequality is real. Children in low and middle income countries often have weaker responses to several common vaccines, and rural communities are hit even harder.

My part was to help track which studies actually shared immunological or omics data. The imbalance was obvious. Almost all public datasets come from Europe and the US, while the places where vaccines perform the worst barely show up.

So we are trying to understand a problem that mainly affects poorer populations using data that come mostly from wealthier ones. HypoVax Global is working to change this by building collaborations, generating better data in underrepresented regions, and giving us a clearer picture of how to reduce this gap.

Important reminder as a third (unvaccinated) baby in Kentucky died from whooping cough this year.

Venez nombreux

Le Dr Paul Marik prétend que les personnes récemment vaccinées « transmettent » la protéine Spike aux non-vaccinés, simplement en se trouvant à proximité ou lors de relations sexuelles.
Et Astrid Stuckelberger surenchérit en affirmant que ces mêmes personnes « dégageraient littéralement » une odeur de viande putréfiée, de nature acide — une “expérience” qu’elle dit avoir faite dans un avion.

On est exactement dans ce que produit le complotisme :
➡️ inventer des mécanismes biologiques inexistants,
➡️ coller des attributs dégradants à un groupe entier,
➡️ présenter des fantasmes comme des faits.

Aucune étude, aucune donnée, aucune cohérence scientifique.
Juste du récit toxique et déshumanisant présenté comme de la science.

🚨 RFK Jr. issues a stark warning: “Our country is in a death spiral” And he is the cause of such by spreading misinformation and falsehoods.

“We pay 2-3x what Europeans paid for healthcare … and we have the worst health outcomes.” The USA, unlike the 32 most industrialized countries in the world, does not offer universal free healthcare, and spend money in it through private providers making these corporations rich rather than American healthier

“When I was a kid, a typical pediatrician would see one case of diabetes in his lifetime.” Thanks to McDonald’s, screen time, and lack of exercise

“Now it's 38% of teens.”

“150 million Americans have BMIs over 30. This is obese.” Americans eat too much and bad food…

“The autism rates … in 1970 were less than 1 in 10,000.” Changes in diagnosis and definition of autism led to a rise in cases

“Today [it’s] 1 in every 12.5 boys in California—1 in every 19 kids.”

“And the other states are similar.” Not true

If you still think we need more "evidence" that vaccines don't cause autism, you likely also need more evidence that the earth is round and that evolution is real. The data are clear and compelling...Vaccines do not cause autism. | 29 comments on LinkedIn

Vaccination plays a key role in improving health and health equity, and addressing health security issues around the world.

However, in many low- and middle-income countries (LMICs), there are many challenges

Addressing these issues calls for strengthening the capacity of local policymakers and researchers, ensuring appropriate skills are developing to generate and understand data, conduct relevant research, and translate evidence into effective immunisation policies

All even more important with so much mis/disinformation

🔷 Une étude de l’Office of Health Economics (OHE) montre que les programmes de vaccination des adultes génèrent jusqu’à 19 fois leur coût initial, soit un bénéfice net moyen estimé à 4 637 $ US par vaccination complète lorsqu’on tient compte de l’ensemble des effets économiques et sociaux.

L’analyse a porté sur quatre vaccins destinés aux adultes :

✅ Grippe saisonnière : prévient les formes graves, les hospitalisations et les pertes de productivité liées aux arrêts de travail.

✅ Pneumocoque : protège contre les pneumonies, septicémies et méningites, particulièrement graves chez les personnes âgées.

✅ Virus respiratoire syncytial (VRS) : réduit les bronchiolites et infections respiratoires aiguës, responsables d’hospitalisations coûteuses chez les sujets fragiles.

✅ Zona : évite les douleurs chroniques (névralgies post-zostériennes) et la perte de qualité de vie qu’elles entraînent.

🔹L’étude a été menée dans 10 pays représentant différents systèmes de santé : Australie, Brésil, France, Allemagne, Italie, Japon, Pologne, Afrique du Sud, Thaïlande et États-Unis.

🔹Les résultats montrent que ces programmes de vaccination allègent significativement la pression sur les systèmes de santé en réduisant les consultations, hospitalisations et complications évitables, tout en soutenant la productivité économique grâce au maintien d’une population active en bonne santé.

🔹Les auteurs soulignent que les retombées socio-économiques sont comparables à celles observées pour la vaccination infantile, mais que l’accès aux vaccins pour adultes reste inégal et souvent exclu des calendriers nationaux de vaccination.

🔹Ils notent aussi un manque de données homogènes et d’outils standardisés pour évaluer l’impact complet, ce qui conduit probablement à sous-estimer la valeur réelle de la vaccination des adultes.

Concerned about ignorance ? Ouf…

La prochaine pandémie n’attendra pas : sommes-nous prêts ?

Dans un éditorial paru dans Nature, l’attention se tourne désormais non pas uniquement vers quel agent pathogène pourrait déclencher la prochaine pandémie, mais surtout vers comment la science et la société seront capables d’y répondre ; et à quelle vitesse.


Voici ce qu’il est pertinent de retenir :
🦠 Il n’est plus suffisant de repérer le virus : l’urgence est de disposer de pipelines intégrés permettant d’identifier, tester, développer et produire en quelques mois des diagnostics, traitements ou vaccins efficaces.
🦠 Le concept de "100 jours" se dessine : du moment du signal d’alerte jusqu’à la disponibilité d’une contre-mesure, le temps doit être drastiquement réduit.
🦠 L’anticipation passe par des approches intégrées : veille des pathogènes dans les réservoirs animaux, intelligence artificielle (comme le modèle CoVFit mentionné dans l’éditorial) pour modéliser le risque, articulation recherche-industrie-régulation.
🦠 La recherche collaborative, interdisciplinaire, et la conversion rapide des découvertes en application clinique ou publique (illustrées par l’exemple du centre UTOPIA) se révèlent des leviers clés pour limiter l’impact humain, social et économique.


En conclusion, dans un monde où les menaces émergentes ne suivent aucun calendrier, l’enjeu n’est plus seulement d’identifier la prochaine épidémie, mais de savoir si nous serons capables d’y répondre suffisamment vite lorsque celle-ci surviendra.

Vaccines & Vaccinations: A Future Agenda for Social Sciences & Policy

24 November 2025
St Cross College, University of Oxford
Hosted by the Vaccines & Society Unit (VAS)

I’m very happy to share that I’ll be joining an incredible group of colleagues at this workshop, which brings together 17 scholars from 16 countries as part of the Forum for Vaccine Social Science (FOVAS).

The event will open a reflexive and forward-looking conversation on how the social sciences can contribute to the future of vaccination—exploring questions of trust, equity, sovereignty, and the social and political lives of vaccines.

When federal agencies fall short, scientific accountability must rise.

The Vaccine Integrity Project led by the University of Minnesota aggregated results from 590 studies to independently assess vaccine safety and effectiveness — providing clarity where political guidance falters.
