Vaccines and Immunology: A Foundation of Preventive Medicine

One of the most impactful applications of immunology is vaccination—a concept built on a simple yet powerful idea: training the immune system before exposure to disease.

The adaptive immune system’s ability to develop long-term memory allows vaccines to provide lasting protection with minimal risk. This principle has transformed global health outcomes and continues to shape modern medical innovation.

What’s particularly remarkable is how advancements in biotechnology—especially mRNA platforms—have accelerated vaccine development timelines without compromising safety or efficacy.

Vaccination is not only an individual health decision; it is a collective responsibility that strengthens public health systems through herd immunity.
As science continues to evolve, the role of immunology in preventive medicine will only become more critical.

The future of healthcare is not just about treating disease—but preventing it.

From Lab to Production Line: Key Aspects of Bioreactors in Vaccine Applications | Shizhou Liu

From Lab to Production Line: Key Aspects of Bioreactors in Vaccine Applications | Shizhou Liu | Immunology and Biotherapies | Scoop.it
The most critical strategy for controlling the spread of infectious diseases is vaccination—making vaccine production processes pivotal to disease control and eventual eradication. Vaccination is an artificial process where inactivated, attenuated infectious pathogens, or their components, are delivered to the human body, using antigenic structures to activate the immune system. This process stimulates an effective response against specific pathogens to combat impending infections.

Since the mid-20th century, viral vaccines have been produced using chicken embryos, with dozens of approved traditional human vaccines manufactured via embryo-based processes. Today, however, cell culture-based vaccine production has become widespread: it enables simple infection and replication in controlled environments, with harvesting steps conducted in closed bioreactor systems to ensure sterility and further reduce biosafety risks through automation. This approach significantly boosts factory capacity, enabling the production of large quantities of vaccine doses.

Sanofi Publishes In Vivo CAR-T Data | Cesare Di Nitto posted on the topic

Sanofi Publishes In Vivo CAR-T Data | Cesare Di Nitto posted on the topic | Immunology and Biotherapies | Scoop.it
Sanofi just published their in vivo CAR-T data.

The paper will be published in 𝘔𝘰𝘭𝘦𝘤𝘶𝘭𝘢𝘳 𝘛𝘩𝘦𝘳𝘢𝘱𝘺 this month.

Was this built in-house? Not really. It's the result of two strategic acquisitions that tell you exactly how big pharma is entering in vivo cell engineering.

Everything started about 8 years ago with Sanofi entering the mRNA therapeutics space first.

In 2018, Sanofi partnered with Translate Bio for mRNA vaccines. $45M upfront. Focusing specifically on up to five infectious diseases.

COVID hit.

They expanded the deal in 2020 to $300M cash + $125M as stock investment, covering all infectious diseases.
Then in August 2021, they acquired the whole company for $3.2B!!!

What did they get? One of the largest private LNP libraries in the industry. mRNA manufacturing expertise. A platform ready to go beyond vaccines.

𝘉𝘶𝘵 𝘮𝘙𝘕𝘈 𝘵𝘦𝘤𝘩 𝘢𝘭𝘰𝘯𝘦 𝘥𝘰𝘦𝘴𝘯'𝘵 𝘮𝘢𝘬𝘦 𝘪𝘯 𝘷𝘪𝘷𝘰 𝘊𝘈𝘙-𝘛 𝘸𝘰𝘳𝘬!

Three months before closing Translate Bio, Sanofi acquired Tidal Therapeutics in April 2021. $160M upfront, $470M total including milestones.

𝗦𝗮𝗻𝗼𝗳𝗶'𝘀 𝘁𝗼𝘁𝗮𝗹 𝗰𝗼𝗺𝗺𝗶𝘁𝗺𝗲𝗻𝘁:
+$𝟯.𝟲𝗕 𝘁𝗼 𝗲𝗻𝘁𝗲𝗿 𝘁𝗵𝗲 𝗺𝗥𝗡𝗔 𝗮𝗻𝗱 𝗶𝗻 𝘃𝗶𝘃𝗼 𝗖𝗔𝗥-𝗧 𝘀𝗽𝗮𝗰𝗲

Tidal brought the missing piece: targeted nanoparticle technology to reprogram immune cells directly in the body.

Now the paper shows what happens when you combine both platforms.

The technical execution is solid:

• Proprietary ionizable lipid 15 for T cell transfection
• Anti-CD8 VHH nanobody outperforming other ligands
• CD22 CAR benchmarked against clinically validated CARs (FMC63 and m971)
• Hepatic de-targeting, under 5% liver uptake
• Tumor suppression in aggressive human models

That last point matters. Getting mRNA into T cells is hard enough.

Keeping it away from liver trapping while maintaining efficacy is the real challenge.

They solved both.

This is how platforms get built in 2025. You don't develop everything internally. You acquire the best technology, integrate it fast, and publish validation data within a few years.

Translate Bio gave them the mRNA engine. Tidal gave them the targeting system. Together, they created an in vivo CAR-T platform neither could build alone.

The question now is whether improvements we witness in the in vivo CAR-T space will scale beyond hematological malignancies.

The delivery is transient.
The safety profile looks clean (mRNA).
Serial killing durability up to 8 days.
And repeat dosing gave no signs of toxicity.

Can this match the persistence of ex vivo products?
Will in vivo CAR-T platforms ever be efficacious in solid tumors?

So much money has been invested in this tech and we are seeing progress with creative solutions to optimize in vivo CAR-T platforms.

Interesting in Cell Stem Cell: In vivo CAR-Tfh cell reprogramming restores tolerance in a mouse model of autoimmune hepatitis
https://lnkd.in/en36DGSU
Autoimmune diseases involve the coordinated dysregulation of multiple types of immune cells, and single-cell targeted therapies often yield suboptimal results. Here, we developed chimeric antigen receptor (CAR)-engineered follicular helper T (Tfh) cells capable of simultaneously suppressing T cells, B cells, and dendritic cells (DCs) to restore immune homeostasis in an autoimmune hepatitis (AIH) mouse model. Using amino acid-derived lipid nanoparticles, we deliver self-amplifying RNA encoding Forkhead box protein P3 (Foxp3) and a cytochrome P4502D6 (CYP2D6)-specific CAR to Tfh cells, conferring stable regulatory features and antigen-dependent suppressive activity. Engineered CAR-Tfh cells preferentially localize to the liver, recognize CYP2D6-expressing hepatocytes, and suppress pathogenic T cell and B cell responses. In AIH-II mouse models, CAR-Tfh cell generation restores a tolerogenic hepatic immune environment and ameliorates autoimmune liver injury. These findings establish in situ Tfh cell reprogramming as a modular approach to coordinately modulate multiple immune compartments, providing a potential therapeutic framework for AIH and related autoimmune diseases.

🔬 Recent Trends in Vaccine Delivery Systems: Transforming Modern Immunization

Vaccines remain one of the most powerful tools in preventive medicine, protecting millions of lives each year.

While traditional vaccines have been highly effective, modern science is now focusing on innovative vaccine delivery systems to improve immunogenicity, stability, and targeted immune responses.

Here are some important advancements shaping the future of vaccination:

🧬 1. Subunit and Recombinant Vaccines

Instead of using whole pathogens, these vaccines use specific antigenic components such as proteins or polysaccharides.

✔ Higher safety profile

✔ Targeted immune response

✔ Reduced adverse reactions

However, these vaccines often require adjuvants to enhance immune stimulation.

💉 2. Advanced Vaccine Delivery Platforms

Modern delivery systems are being designed to optimize antigen presentation and immune activation.

Key technologies include:

• Liposomes – Lipid-based vesicles that encapsulate antigens and improve immune recognition

• Microparticles / Nanoparticles – Controlled release systems that enhance antigen stability

• ISCOMs (Immune Stimulating Complexes) – Improve antigen uptake by antigen-presenting cells

• Emulsion-based delivery systems – Facilitate sustained antigen release
These technologies help ensure better immune activation with lower antigen doses.

🧪 3. Role of Adjuvants

Adjuvants play a critical role in vaccine effectiveness by:

✔ Enhancing immune response

✔ Promoting long-lasting immunity

✔ Reducing the amount of antigen required

They function by stimulating pattern recognition receptors (PRRs) of the innate immune system, thereby strengthening adaptive immune responses.

🌍 Why This Matters

The development of advanced vaccine delivery systems is critical for:

• Emerging infectious diseases

• Pandemic preparedness

• Cancer immunotherapy

• Chronic viral infections such as hepatitis

These innovations are helping us move toward safer, more effective, and more targeted immunization strategies.

💡 Key Takeaway

The future of vaccination is not just about the antigen itself, but also about how it is delivered to the immune system.

Modern delivery platforms and adjuvants are revolutionizing vaccine science and opening new possibilities for global disease prevention.

🔗 Let’s continue advancing collaborative research in microbiology, immunology, and pharmaceutical sciences to strengthen global health security.

Gostaria de compartilhar o artigo “A segurança e a inovação de vacinas no Brasil”, publicado na seção Tendências/Debates, na edição de 1° de março no jornal “Folha de S. Paulo", do qual sou co-autor. 
O texto discute um ponto central para o futuro da saúde no país: como equilibrar proteção regulatória, ética e agilidade para permitir que a inovação nacional floresça.
Embora o Brasil possua instituições regulatórias sólidas, ainda enfrentamos desafios estruturais que impactam diretamente a competitividade científica e tecnológica. A morosidade e a assimetria regulatória acabam favorecendo grandes players internacionais e dificultando o avanço de vacinas concebidas e desenvolvidas no país.
A pandemia deixou clara a importância da soberania tecnológica em saúde. Fortalecer o ecossistema nacional de inovação exige não apenas financiamento, mas também um ambiente regulatório moderno, previsível e adaptativo.
A recente Lei 14.874/2025 e iniciativas de acompanhamento regulatório representam passos importantes. O desafio agora é transformar expectativa em implementação efetiva.
Seguimos trabalhando para que ciência, ética e desenvolvimento caminhem juntos — com protagonismo brasileiro.

Researchers at Virginia Tech are developing a new class of #vaccines designed to block #opioids from reaching the #brain - an approach that could help address the ongoing #overdose crisis in the United States.

▫️ In a study published in the Journal of Controlled Release, a team led by Chenming Zhang , professor and Turner Faculty Fellow in the Department of Biological Systems Engineering, created a hybrid lipid-polymer #nanoparticle #vaccine that triggered stronger #immuneresponses and improved protection against #oxycodone in mice. The work was supported by The National Institutes of Health and involved contributions from undergraduate researcher Kari Cochran from the Virginia Tech College of Engineering.

▫️The vaccine uses biodegradable nanoparticles that mimic viruses in size and structure, prompting the #immunesystem to produce #antibodies that bind to opioid molecules such as oxycodone or #fentanyl. By preventing these drugs from crossing the blood–brain barrier, the approach blocks the euphoric effects that drive addiction while still allowing other medical treatments to function normally.

▫️Early findings suggest the antibodies remain active for months and could potentially be optimized to provide year-long protection. While not intended for general vaccination, the strategy could be used for individuals with opioid use disorder or those at high risk of exposure.

💡 If successful, this research could open a new frontier where vaccines are used not only to prevent #infectiousdiseases but also to address chronic conditions like #addiction, potentially reducing overdose deaths and supporting recovery.

Vaccination Dynamics in Dairy Cattle: Understanding Antibody Titre | Mushrraf Nazir posted on the topic | Immunology and Biotherapies | Scoop.it
🐄 Understanding Vaccination & Antibody Titre Dynamics in Dairy Cattle 🧬

Effective vaccination is not just about injecting vaccines—it’s about understanding how the immune system responds and how long protection lasts.

🔬 What happens after vaccination?
The animal’s immune system produces antibodies. The first response is slow and low, while booster doses create a faster and stronger immunity.

📊 Antibody Titre Dynamics:
Antibody levels follow a pattern:
➡️ Lag Phase → 📈 Peak → 📉 Decline

This is why timely booster doses are essential to maintain protection.

🐮 Maternal Antibodies in Calves:

- Obtained through colostrum
- Provide early protection
- Can interfere with early vaccination

⏳ Proper timing of vaccination in calves is critical to avoid vaccine failure.

📅 Practical Vaccination Strategy:

- Calves: 3–6 months
- Boosters: 2–4 weeks after first dose
- Adults: Annual or biannual vaccination

⚠️ Factors Affecting Immune Response:

- Nutrition (Protein, Zinc, Selenium)
- Stress & disease conditions
- Proper vaccine storage & handling (cold chain)

🧪 Why Antibody Titre Testing Matters?

- Evaluate vaccine effectiveness
- Monitor herd immunity
- Optimize vaccination programs
(Common method: ELISA)

💡 Key Takeaways:
✔ Boosters are critical
✔ Good nutrition improves immunity
✔ Monitor and adapt vaccination plans

🌱 Strong immunity = Healthy herd = Better productivity

Type I interferon restricts mRNA vaccine efficacy through suppression of antigen uptake in cDCs - npj Vaccines | Miroslav Gasparek

Type I interferon restricts mRNA vaccine efficacy through suppression of antigen uptake in cDCs - npj Vaccines | Miroslav Gasparek | Immunology and Biotherapies | Scoop.it
The immune system can be your best friend for mRNA vaccines - and also your biggest bottleneck.

A new paper in npj Vaccines by Lobb et al., highlights a counterintuitive point: type I interferon (IFN), a key innate immune alarm signal, can reduce mRNA-LNP vaccine effectiveness if it’s triggered at the wrong time, because activated dendritic cells lose the ability to take up new antigen.

In their models, blocking IFNα/β receptor signaling before vaccination (or removing the receptor specifically in dendritic cells) increased vaccine uptake/expression in DCs, improved CD8⁺ T-cell priming, and led to better tumor control. They also show a practical implication: IFN already “in the system” (for example after an infection or a recent prior vaccination) can blunt the response to an mRNA-LNP vaccine given shortly afterwards.

This connects directly to a theme we care about at Sensible Biotechnologies: for mRNA medicines, purity and innate immune activation are not “nice-to-have” quality attributes - they can materially shape uptake, translation, and ultimately efficacy. If IFN signaling suppresses antigen acquisition and translation capacity in key antigen-presenting cells, then minimizing unnecessary innate triggers (including those driven by impurities) becomes part of the performance equation, not just the safety story.

That’s why Sensible is focused on maximizing mRNA purity and minimizing immunogenicity as we build a vertically integrated, cell-based platform for mRNA design and manufacturing.

 • Clinical efficacy: While response rates in solid tumors remain modest overall, clear “pockets of promise” exist in neuroblastoma (GD2), sarcoma (HER2), and glioblastoma (IL-13Rα2), with some trials reporting complete response rates up to ~31%.
 • Biological barriers: Major challenges include antigen heterogeneity, on-target off-tumor toxicity, poor T cell trafficking, and an immunosuppressive tumor microenvironment. The field is moving toward armored CARs (for example IL-12 or IL-15 secreting cells) and logic-gated circuits such as SynNotch to improve specificity and persistence.
 • Manufacturing innovation: New ex vivo strategies — including metabolic priming with L-arginine and shortened vein-to-vein production (24–72 h) — aim to preserve T cell stemness and reduce exhaustion.
 • Emerging platforms: Allogeneic “off-the-shelf” CAR-T products and in vivo CAR engineering using lipid nanoparticles are being explored to overcome scalability and manufacturing complexity.

But you might not know about CAAR-T - a newer, more targeted twist on the same technology:

So what is it?
- CAAR-T (Chimeric AutoAntibody Receptor T cells) are designed to eliminate only the B cells producing harmful autoantibodies, while sparing the rest.
- Instead of using an antibody fragment to find targets (like CAR-T does), CAAR-T cells display an autoantigen on their surface, tricking autoreactive B cells into binding and revealing themselves.

Here’s how they compare:

CAR-T Cells
Advantages:
- Targets all B cells via markers like CD19
- Proven success in cancer and autoimmune diseases (e.g., lupus)
Disadvantages:
- Destroys healthy B cells too, leading to broader immune impact
- Can cause CRS, especially with large-scale immune activation

CAAR-T Cells
Advantages:
- Precisely targets only B cells producing harmful autoantibodies
- Spares healthy B cells, preserving immune function
Disadvantages:
- Requires known autoantigen (e.g., Dsg3, MuSK)
- Limited clinical experience, still early in development

In short:
CAR-T is broad and proven.
CAAR-T is precise and emerging.

Now, I don't see CAAR-T replacing CAR-T.

But for autoantibody-driven diseases, it could offer something we’ve never had before:
A precise strike against the root cause, without wiping out the entire immune arsenal.

Butantan Dengue Vaccine 81% Effective Against Severe Disease for 5 years -

The results of a phase 3 clinical trial of the Butanan vaccine are now published in Nature Medicine. The single-dose tetravalent dengue vaccine developed by Brazil’s Butantan Institute is 80.5% effective against hospitalization for the mosquito-borne disease for at least five years.

The double-blind, placebo-controlled trial included 10,259 vaccinated individuals and  5,976 in the placebo control.

Over five years, no vaccinated participants were hospitalized. VE against symptomatic dengue was 65.0%. VE was 77.1% in previously infected participants, 58.9% in dengue-naive participants, 73.0% against DENV-1, and 55.7% against DENV-2. Cases of DENV-3 and DENV-4 weren’t observed.

Beyond suppression: the paradox of JAK inhibitors as amplifiers of cancer immunotherapy | Nature Reviews Immunology

Beyond suppression: the paradox of JAK inhibitors as amplifiers of cancer immunotherapy | Nature Reviews Immunology | Immunology and Biotherapies | Scoop.it
JAK inhibitors target a large group of cytokines that signal through the JAK–STAT pathway and are typically used clinically as immunosuppressive agents. However, recent work has demonstrated the paradoxical ability of JAK inhibitors to enhance antitumour and antiviral immune responses and established their synergy with immune checkpoint inhibitors in early-stage clinical trials. In this Perspective, we consider why JAK inhibitors, which are typically used as immunosuppressive drugs, can have immune-enhancing effects, exploring the potential mechanistic basis and the opportunities to harness this effect to improve cancer immunotherapy. JAK inhibitors are typically used to suppress the immune system but have also been shown to enhance antitumour and antiviral immune responses. In this Perspective, Zak and Teijaro explore the basis of the immune-enhancing properties of JAK inhibitors and consider whether we can exploit these properties for cancer therapy.
