The Limitations of the BCG Vaccine and the Need for a New Solution

The BCG vaccine, created in 1921, is the only TB vaccine available. But it mainly protects kids against severe TB. It doesn’t help much against adult TB or stop the disease from spreading. We clearly need a better vaccine to fight TB effectively.

A study in “Hum Vaccin Immunother” looked at how new TB vaccines could help. It found that a vaccine with 50% effectiveness could prevent 76 million new TB cases and 8.5 million deaths over 25 years.

“An investment of $1 in delivering an effective new TB vaccine could lead to an economic return of $7 over the same period.”

The world is still fighting the effects of TB. mRNA technology offers hope for a better TB vaccine. It could make fighting TB more effective and accessible.

Tuberculosis, mRNA vaccines: A Deadly Global Burden

Tuberculosis (TB) is a big health issue worldwide, affecting about 7.5 million people and causing 1.3 million deaths in 2022. It mainly hits developing countries. Eight countries, like India, China, and South Africa, have most of the TB cases.

The Devastating Impact of Tuberculosis Worldwide

TB’s impact is huge, especially in poor areas. It’s a top cause of death from infectious diseases, after COVID-19. It mainly affects those who are most vulnerable, which worsens poverty and health in many places.

The Challenges of Current Diagnostic Tools and Treatment Options

Even with new tech, finding TB is hard. Old tests aren’t very good, and new ones need a lot of skill. Also, TB bacteria that don’t respond to drugs are becoming more common.

This makes treating TB hard. The treatment can last up to six months, which many people can’t follow. This leads to more resistance, making TB harder to fight.

We really need better ways to fight TB. Innovative solutions, like mRNA vaccines, could change how we prevent and treat TB. They offer hope for millions suffering from this deadly disease.

Exploring the Potential of mRNA Technology

The journey to use mRNA technology for Tuberculosis (TB) prevention started long ago. In 2004, researchers in the UK showed that an mRNA vaccine could protect mice against Mycobacterium tuberculosis. This early work set the stage for today’s exciting advances.

Early Research on mRNA Vaccines for Tuberculosis

In July 2022, BioNTech, a German biotech company, said it would start clinical trials for its mRNA TB vaccine. This was just two years after starting the project. It shows how fast mRNA technology can move.

The success of mRNA vaccines against COVID-19 has sparked new hope for fighting Tuberculosis. Over 670 million doses of mRNA vaccines have been given to people in the US. This shows how powerful this technology is.

“The mRNA vaccines developed in response to covid-19 allowed for a quick turnaround, with clinical trials starting in March after the virus was sequenced in January.”

With years of research and a history of speeding up vaccine development, mRNA technology is set to change the fight against Tuberculosis. This disease has been a major health issue for a long time.

The Power of Multi-Omics in TB Vaccine Development

Fighting TB globally needs new ways that go beyond the old BCG vaccine and tests. Using multi-omics, we combine genomics, transcriptomics, proteomics, and metabolomics. This helps us understand TB better, how it affects us, and find new vaccine markers.

Unlocking the Potential of Multi-Omics

With multi-omics, researchers can see how TB and our immune system interact. This helps us find new markers for TB tests, improve vaccines, and create better treatments.

Studies using multi-omics have given us new insights into TB. They show how TB spreads, how it becomes resistant to drugs, and how our immune system reacts. This knowledge is key to finding new ways to fight TB.

Driving Biomarker Discovery and Vaccine Development

Multi-omics is key in finding new biomarkers for TB vaccines. These markers can tell us about the disease, how treatments work, and who is protected. This helps make better vaccines.

It also helps us understand how our immune system fights TB and vaccines. By knowing which genes, proteins, and metabolites are important, we can make vaccines that work better and last longer.

“By leveraging the power of multi-omics, we can unlock a new era of TB prevention and control, paving the way for more effective vaccines, diagnostics, and targeted therapies.”

As scientists keep exploring multi-omics in TB research, we’re getting closer to understanding the disease better. This could lead to new ways to fight TB, saving millions of lives around the world.

Improved TB Diagnostics Through Multi-Omics

The use of multi-omics approaches could change how we diagnose tuberculosis (TB). By looking at the whole transcriptomes, proteomes, and metabolomes of TB patients and healthy people, researchers can find new biomarkers. These biomarkers are linked to TB infection.

These new insights help in making fast, reliable, and easy tests that don’t just use sputum. This is especially good news for TB patients who also have HIV or are children. They often find it hard to give good sputum samples. The potential of multi-omics-based diagnostics to be used right at the doctor’s office makes them even more useful and easy to get.

Key Findings from Multi-Omics Research	Potential Impact on TB Diagnostics
Identification of 3,427 differentially expressed genes (DEGs) across different clinical condition groups (DM, TB, TBDM) Shared 12 DEGs between TB and TBDM groups, and 6 DEGs between TB and DM groups Principal component analysis (PCA) model able to differentiate between groups based on the presence or absence of TB disease Higher molecular degree of perturbation (MDP) scores in TB and TBDM groups compared to other groups Top informative genes for distinguishing clinical conditions: SMARCD3, VAMP5, ANKRD22, and BATF2	Development of novel, non-sputum-based multi-omics-derived biomarkers for improved TB diagnosis Potential for multi-omics-informed rapid tests and point-of-care diagnostics Enhanced accuracy and efficiency in TB diagnosis, especially for co-infected and pediatric populations

TB still affects many people worldwide, with 10 million new cases and 1.6 million deaths in 2022. The progress in multi-omics-driven TB diagnostics is a big step forward. It promises better early detection, monitoring, and treatment tailored to each patient.

Rational Drug Production for Tuberculosis

Drug-resistant strains of Mycobacterium tuberculosis (MTBC) have made finding new treatments urgent. Multi-omics strategies are now key in this fight. They help find new targets and check if drugs work well or are safe.

Identifying Novel Druggable Targets with Multi-Omics

Tools like transcriptomics, proteomics, and metabolomics help spot important MTBC genes and proteins. These multi-omics methods show us where to aim drugs to stop MTBC from spreading.

A study used immunoinformatics tools to make a TB vaccine. It focused on proteins that change the host’s genes during TB infection. This helped predict and test vaccine parts that work well and are safe.

Epigenetic changes by MTBC also affect host genes linked to the immune system. Targeting these changes could help the immune system fight TB better. This could lead to better TB treatments.

“The emergence of drug-resistant MTBC strains necessitates the discovery of novel therapeutics. Multi-omics strategies can contribute significantly to this critical endeavor through rapid identification of new druggable targets and evaluating efficacy and/or safety of administered drug candidates.”

Using multi-omics, scientists can quickly find new drug targets and make better TB drugs. This helps in the battle against drug-resistant TB.

Recent Milestones in TB Vaccine Research

The search for better tuberculosis (TB) vaccines has seen two big steps forward. These breakthroughs highlight the promise of subunit vaccines and new ways to improve the BCG vaccine. The BCG vaccine is the only one we have now.

The Promising M72/AS01E Subunit Vaccine Trial

A phase 2b trial tested the M72/AS01E subunit vaccine. It has two proteins from Mycobacterium tuberculosis (Mtb). The results were good. The vaccine gave 54.0% protection against active TB disease at first.

By month 36, it was still protecting 49.7% of people. This is the first time a subunit vaccine stopped TB from becoming active in infected people.

BCG Revaccination and Alternative Delivery Routes

There’s also a study on revaccinating with BCG to prevent Mtb infection in high-risk teens. It didn’t stop infection as much as hoped. But, it did reduce the chance of TB infection by 45.4%.

More studies are needed to prove BCG revaccination works well. These efforts show we’re working hard to make better tuberculosis vaccines. We’re using new types of vaccines and new ways to make the BCG vaccine better.

Vaccine Candidate	Clinical Trial Stage	Key Findings
M72/AS01E	Phase 2b	Provided 49.7% protection against active pulmonary TB disease
BCG Revaccination	Phase 2	Showed 45.4% efficacy in preventing sustained IGRA conversion

“These advancements showcase the potential of both subunit tuberculosis vaccines and novel approaches to BCG, the only licensed TB vaccine currently available.”
