Something I think about often as someone trained in laboratory medicine is how much happens inside the body that we never feel or see.

A vaccine is a perfect example. A fraction of a milliliter goes into your arm. Maybe it is sore for a day. And then nothing, at least nothing you can feel. But inside, your immune system has just received one of the most important lessons of its life.

In my latest piece I break down exactly what that lesson looks like at a cellular level, from the first alarm signals at the injection site, to memory cells forming quietly in your lymph nodes, ready to respond years from now to a threat they have never actually faced.
I also write about something that does not get discussed enough. Two of the most powerful cancer prevention tools we have are vaccines.
The Hepatitis B vaccine and the HPV vaccine. In Sub-Saharan Africa where both infections drive cancers that are taking lives that did not have to be lost, expanding access to these vaccines is not just a public health goal. It is urgent.

Happy to conclude another online Vaccinology Course, this time with a strong emphasis on the One Health perspective, bringing together more than 70 participants from Asia, Africa, and Oceania.

Interestingly, most attendees were not physicians, further highlighting the inherently multidisciplinary nature of vaccines, vaccinology, and vaccination, and their relevance far beyond clinical medicine.

From public health and veterinary sciences to environmental health, policy, and community engagement, the future of vaccinology depends on collaboration across disciplines.

Proud to see Think Vaccines® working in alignment with the current needs of our planet and contributing to the advancement of a truly global and interconnected vision of health.

Did you know that 72.6% of severe spinal poliomyelitis cases do not rest after feeling sick? No tonsils and no rest for recovery are major risk factors for polio leading to paralysis.

A week ago, Albert Sabin's story officially entered the world. I'm thrilled that Sabin’s biography – a labor of eight years of research and writing – is now available to readers!

It's been an honor to tell the story of the scientist whose oral polio vaccine helped transform global public health and of the complex, fascinating man behind that achievement.

Vaxelis is safe, and you should ignore anything and everything posted by Andrew Bridgen and Jeffrey Barke, as it is almost certainly going to be pure propaganda to scare you away from getting vaccinated and protected. https://lnkd.in/g9nW8g9v

A comprehensive review found that mRNA vaccines — a popular target of viral vaccine conspiracy theories and medical misinformation in the wake of the COVID-19 pandemic — are a resoundingly safe and effective feat of modern medicine.

Published this week in the journal The Lancet, the review confirmed that mRNA vaccines are robustly effective at preventing the spread of infectious diseases like COVID, and show incredible promise for treating diseases like cancer as well. It was conducted by an international team of researchers based in Canada, Hong Kong, the United Kingdom, and the United States, and took the drug’s manufacturing, clinical trials, and data from billions of real-world vaccinations into account.

"On June 30, 2026, a panel of the Second Circuit Court of Appeals once again rejected a case brought by Amish schools and Amish parents who argued that New York’s refusal to allow them a religious exemption violated their freedom of religion. The decision was a result of the Supreme Court sending the case back for reconsideration in light of a recent decision, and the 2nd Circuit panel decided that the recent decision did not change the result. This post explains the case.
...
Plaintiffs’ argument here is that if parents have a right to direct the religious upbringing of their children, they can decide not to vaccinate if they have religious opposition to vaccines. I hope it’s obvious to readers that this is a problematic comparison. Objecting to the content of the curriculum is not the same as objecting to health and safety rules like a vaccination requirement – what if the parents argue that a child’s religion requires bringing a sword to school and killing anyone who disagrees religiously? But that’s the plaintiff’s argument, and observers – including well-informed observers – saw it as a warning sign that the Supreme Court may require religious exemptions from school mandates.
If so, the Second Circuit did not take the hint, and it doubled down, essentially telling the Supreme Court that if it wants to overturn decades of precedent that do not require religious exemptions from vaccine mandates, it will have to do the dirty work itself.
...
I think there is a good chance the plaintiffs will appeal to the Supreme Court. What then? First, I’m not sure the Court will want to take the case. The Court has been avoiding vaccine mandate cases, and as far as I know, has not taken up a school mandate case since Zucht v. King in 1922.

And if it takes it? First, I will point out that there are very smart people who think the Court would find for the plaintiffs and require a religious exemption. Me? I think it’s a toss-up. The grant, vacate, and remand suggested the Supreme Court thinks there might be something there. But if the Court was sure, it could have decided the case directly, as it did other cases. The GVR suggests to me that the Court did want the benefit of more examination.

This does not mean the Court will not overturn the 2nd Circuit on remand. But requiring a religious exemption from a school mandate is a big, big change, going against decades of precedent. The Court has certainly done it, and might again. But it’s not clear that it will. By my count, we have three justices for requiring religious exemptions: Justices Alito, Thomas, and Gorsuch have expressed their views that way.

We have three justices clearly against requiring it: Justices Sotomayor, Kagan, and Jackson.

So the question is which way will Justices Barrett, Kavanaugh, and Chief Justice Roberts fall."

RESILIENCE: PUBLIC HEALTH´S MOST POWERFUL MEDICINE

Albert Sabin's story did not begin in a laboratory.

It began with resilience.

Born to a Jewish family that left Europe during a period of growing persecution, Sabin's future might never have existed had his family chosen to surrender to circumstances.

Years later, as a scientist, he pursued a different path from Jonas Salk in the fight against polio.

Salk developed an injectable vaccine based on an inactivated virus.

Sabin believed that an oral vaccine based on an attenuated virus could play a critical role in large-scale immunization campaigns.

Science advanced because both approaches were explored.

But the road was not simple.

Sabin spent years researching, testing, refining, and defending his ideas. When large-scale testing did not move forward in the United States, studies involving millions of children were eventually conducted elsewhere, including the Soviet Union.

The results helped transform the global fight against one of the most feared diseases of the twentieth century.

Sometimes I wonder:

What if his family had given up?

What if he had abandoned his hypothesis at the first obstacle?

What if he had accepted that the door was closed?

Innovation is rarely a straight line.

It is often the product of people who continue moving forward when uncertainty, criticism, and setbacks suggest they should stop.

Not every unconventional idea will prove correct.

But no unconventional idea will ever prove its value if it is abandoned before it is tested.

Before vaccines, before clinical trials, before scientific breakthroughs, there was something else:

Resilience.

And perhaps it remains public health's most powerful medicine.

When many people are vaccinated, they also help protect those who are too young or unable to be vaccinated themselves. That's the power of community immunity.

But when groups of unvaccinated people build up, diseases can spread more easily and outbreaks can occur.

Antivaxxers on the LinkedIn, take notice! Over 13,000,000,000 doses administered, safe and effective, not only against COVID-19 but other coronaviruses.

Compare this with case reports and wild, imaginative hypotheses put forward by individuals looking to make money on misinformation.

Anti-vaccine influencers are upset that the cornerstone of their evidence that vaccines are associated with SIDS has been removed, because vaccines ARE NOT associated with SIDS. https://lnkd.in/gHSB4mnc

The Dangerous Intersection of Viral Misinformation and Criminal Justice

When an Idaho mother claimed her 18-month-old twin toddlers died as a direct result of routine childhood vaccinations, the narrative was immediately weaponised.

Promoted heavily by Children’s Health Defense (CHD) and integrated as physical "evidence" into a high-stakes federal lawsuit involving HHS Secretary Robert F. Kennedy Jr., the case became a cornerstone argument against standard immunization schedules.

However, a intensive, year-long forensic investigation by law enforcement has completely shattered this narrative.

A grand jury has officially indicted 23-year-old Andrea Shaw on two counts of First-Degree Murder. According to court arraignment records, forensic evidence reveals the true cause of death was not vaccine injury—it was suffocation.

This case highlights a deeply disturbing trend: how tragic real-world events are prematurely codified into legal battles and public health campaigns before the criminal justice process can uncover the facts.

Tech ARP breaks down the timeline, the forensic evidence, and the legal fallout in our latest deep dive.

Happy Tin Foil Tuesday!

I do not care what anyone says. Ivermectin was clearly the best treatment for COVID.

Think about it.

If it can deal with worms in my backside, why would it not work on a crown shaped virus? Science.

Do not come at me with your fancy immunology either.

Apparently the vaccines were designed to produce viral antigens from mRNA without exposing people to the live virus. Sounds suspiciously like something a person who understands biology would say.

And what about myocarditis?
Myocarditis!
Do you not speak Spanish?
Myocarditis! Myocarditis!

I have absolutely no idea what it means, but I know if I say it loudly enough it wins arguments on Facebook.

Do not you dare tell me that COVID itself can also cause myocarditis, often at higher rates. I am not interested in context. Context is how Big Science gets you.

The real reason vaccines were developed was obviously to suppress sales of ivermectin. Never mind that ivermectin repeatedly failed to demonstrate meaningful efficacy against COVID in well conducted clinical trials. That is exactly what they want you to think.

And before anyone says otherwise, some famous politicians took ivermectin and still got COVID.

Which somehow proves it works.

Do not ask questions.

Now they expect me to believe that mRNA technology, which had been under development for years before COVID, is being investigated for cancer treatments, rare diseases, regenerative medicine, and helping repair damaged tissues.

Right.

What next?

You are going to tell me that understanding how a technology works allows scientists to adapt it for different medical problems?

Pull the other one.

Next you will be telling me my children should have measles vaccines because exposing them to a highly infectious disease with potentially serious complications is somehow less sensible than preventing it in the first place.

Honestly, where does it end?

Anyway, I am off to buy horse dewormer, ignore decades of virology, and explain to several immunologists why my Favorite manly comedian podcast has uncovered what the world's leading researchers somehow missed.

Happy Tin Foil Tuesday.

🔎📰 SUMMERTIME calls for some easy reading. I guess The Non-Specific Vaccine Effects Journal Club hardly qualifies as that – except perhaps this time it does😉

In this 30th issue I invite you to reflect on what seems to be the most obvious blind spot in the scientific community that has if not endorsed - at least accepted the concept of non-specific vaccine effects (NSE) for decades.

Here's some serious party spoiling:
NSE is as evidence based as bloodletting, hysterectomy for depression, and a more recent example hydroxychloroquine for the treatment of Covid infections.

Notably, all of the above managed at varying extent to gain scientific attention and even acceptance.

The anatomy of collective deception 🤥 is the topic of this summer edition of the JC, where we will dig into why NSE is a biological impossibility.

Many of the most significant vaccination challenges of the last decade have shared a common lesson. The science worked. What surrounded it often did not.

That is the central premise of our new edited volume, 'Socio-Technological Relationships in Vaccine Systems', which I had the pleasure of co-editing with Omkar Nadh.

Over the past two years, colleagues from law, public health, science and technology studies, and other disciplines have worked together to examine how vaccine systems actually function.

Rather than viewing vaccination as a simple journey from discovery to delivery, the book explores the complex relationships among governance, financing, regulation, institutions, trust and power that determine whether vaccines reach the people who need them.

I am delighted to see the book now in print and grateful to the outstanding contributors whose expertise made this interdisciplinary project possible.

For researchers, policymakers and practitioners working on vaccine governance, health innovation and equitable access, I hope this book offers new perspectives and valuable insights.

Albert Sabin, inventor of the live-attenuated oral polio vaccine, arrived in the USA at age 15 years after antisemitic pogroms forced his family to leave their native Poland. Jonas Salk's mother, to whom he credited his interest in medicine that led to development of the first inactivated injectable polio vaccine, was able to follow her sister to the USA at age 12 years thanks to family reunification policies..."

There’s a lot of information about childhood #vaccines online, and it can be challenging for parents to know which sources to trust.

To help Chinese-speaking families make informed decisions about immunisation, National Centre for Immunisation Research and Surveillance (NCIRS) expert Dr Lucy Deng answers some of the most common questions about childhood immunisation in #Cantonese, including: 

❓Why are childhood vaccines important? 
❓Why is it important to vaccinate on time? 
❓Where can families find reliable, evidence-based information?

🎥 Watch Dr Deng’s video: https://lnkd.in/grCfv9Ed

What does it take to prove that a vaccine works?

In 1954, over 1.8 million children participated in what became the largest clinical trial in history. The results changed public health forever.

The story of the polio vaccine isn't just about scientific discovery—it's about rigorous research, ethical clinical trials, and the power of evidence to transform lives.

As someone passionate about clinical research and public health, I find these landmark studies incredibly inspiring. They remind us that every breakthrough we rely on today is built on years of careful research and the willingness of countless individuals to contribute to science.

This reel is part of my series exploring the pivotal studies and discoveries that have shaped modern medicine.

I'd love to hear: Which landmark medical study or breakthrough do you think every healthcare professional should know about?

La vaccination contre la fièvre jaune se situe au croisement de plusieurs enjeux : évaluation du risque infectieux, exigences d'entrée dans certains pays, contre-indications et contexte clinique.

Comment intégrer tous ces éléments pour formuler une recommandation adaptée à chaque voyageur?

Après avoir abordé la prévention de la méningococcie invasive, l'échange se poursuit avec Dre Dominique Tessier pour explorer cette fois la prévention de la fièvre jaune.

Ensemble, nous discutons des critères qui orientent la recommandation vaccinale, des situations où le jugement clinique prend toute sa place et des défis bien réels rencontrés en consultation pré-voyage.

Un épisode éclairant qui illustre toute la complexité de la recommandation vaccinale, où les lignes directrices, les exigences réglementaires et la réalité de chaque voyageur doivent être considérées de façon intégrée.

Yes, this graphic is a little cheeky. But the reality behind it is our whole "why."

The internet is a double-edged sword. It connects us and lets good information travel fast, but it's also become a superspreader of bad information. And bad information has consequences, especially when it comes to your health.

You've probably heard "do your own research." It's a tricky phrase, because there are real limits to what any of us can evaluate outside our own training, and that's true for everyone (including us). But the reality is we're all online consuming information, and most of us are going to look things up. So instead of telling you not to, we want to be a resource that supports that curiosity with the best available evidence.

If you're here, thank you. We want this to be a space where you can ask about anything, including the claims you've seen circulating online. Our goal is to help you sort the true from the false and make the decisions that are right for you and your family.
