Key recent advances in TB vaccine development and understanding of
1.1. TB global epidemiology. Even in the time of SARS-CoV-2, tuberculosis (TB) is to date the leading global infectious killer due to a single pathogen (i.e., the bacterium, Mycobacterium tuberculosis (Mtb)), and one of the world's top ten causes of death. According to the World Health Organization [], there were an estimated 10 million new cases and 1.4 million deaths due to TB in 2019.
Key advances in vaccine development for tuberculosis—success and

Accelerating research and development of new vaccines against
To eliminate tuberculosis globally, a new, effective, and affordable vaccine is urgently needed, particularly for use in adults and adolescents in low-income and middle-income countries. We have created a roadmap that lists the actions needed to accelerate tuberculosis vaccine research and development using a participatory process. The vaccine pipeline needs more diverse immunological ...
The status of tuberculosis vaccine development
Tuberculosis represents the leading global cause of death from an infectious agent. Controlling the tuberculosis epidemic thus represents an urgent global public health priority. Epidemiological modelling suggests that, although drug treatments for tuberculosis continue to improve, WHO timelines to control the spread of the disease require a new vaccine capable of preventing tuberculosis ...
Clinical trials of tuberculosis vaccines in the era of increased access
Approximately 10·6 million people worldwide develop tuberculosis each year, representing a failure in epidemic control that is accentuated by the absence of effective vaccines to prevent infection or disease in adolescents and adults. Without effective vaccines, tuberculosis prevention has relied on testing for Mycobacterium tuberculosis infection and treating with antibiotics to prevent ...
Tuberculosis prevention: current strategies and future directions
Better tuberculosis vaccines and innovative strategies are urgently needed to overcome the current tuberculosis crisis.

Vaccines against Tuberculosis: Where Are We and Where Do We Need to Go
In this review we discuss recent progress in the development, testing, and clinical evaluation of new vaccines against tuberculosis (TB). Over the last 20 years, tremendous progress has been made in TB vaccine research and development: from a pipeline virtually empty of new TB candidate vaccines in the early 1990s, to an era in which a dozen novel TB vaccine candidates have been and are being ...

Tuberculosis vaccines: Rising opportunities
A vaccine preventing pulmonary tuberculosis (TB) in adults is needed but has long been considered an elusive goal. Times are changing in the field of TB vaccines, though, with recent results boosting confidence in the feasibility of a TB vaccine with potential as a decisive tool in the fight against TB. Mycobacterium tuberculosis (Mtb), the ...
Final Analysis of a Trial of M72/AS01E Vaccine to Prevent Tuberculosis
Results of an earlier analysis of a trial of the M72/AS01E candidate vaccine against Mycobacterium tuberculosis showed that in infected adults, the vaccine provided 54.0% protection against active ...
TB vaccine: WHO expert explains why it's taken 100 years for a
In 2021 10.6 million people developed TB and 1.6 million died from the disease. Now, for the first time in 100 years, there are promising signs of a vaccine breakthrough.
Covid-19's Devastating Effect on Tuberculosis Care
Investments in new tuberculosis vaccines amount to barely $0.1 billion per year, and overall research and development investments reached only $0.9 billion in 2020, as compared with an estimated ...
Status of vaccine research and development of vaccines for tuberculosis
Research and development is one of the three pillars of the WHO TB strategy, and will play a crucial role in accelerating the reductions in TB incidence and mortality required to reach global TB targets to reduce TB deaths by 95% and to reduce new infections by 90% between 2015 and 2035. Better control of TB than that provided by BCG could be ...
A new tuberculosis vaccine: breakthrough, challenges, and a call for
Tuberculosis is the deadliest infectious disease in human history, and remains the leading cause of death from a single infectious agent globally. WHO estimates that tuberculosis caused illness in 10 million people and claimed 1·6 million lives in 2017 alone.1,2 Currently, tuberculosis is responsible for a quarter of annual deaths due to antimicrobial resistance, and remains the primary cause ...
Review of Current Tuberculosis Human Infection Studies for Use in
Abstract. Tools to evaluate and accelerate tuberculosis (TB) vaccine development are needed to advance global TB control strategies. Validated human infection studies for TB have the potential to facilitate breakthroughs in understanding disease pathogenesis, identify correlates of protection, develop diagnostic tools, and accelerate and de-risk vaccine and drug development.
Researchers discover a potential vaccine to prevent tuberculosis in
Researchers sought to modify the BCG vaccine to make it more effective at controlling the growth of M. tuberculosis. Mice injected with the edited BCG vaccine had less M. tuberculosis growth in their lungs than mice that received the original vaccine. "We can now offer a new candidate vaccine in the fight against this deadly disease," says Kana.
