Families affected by tuberculosis (TB) face many challenges because of different health, social, and structural problems which overlap and interact. Traditional approaches to tuberculosis screening do not address pre-existing risks. In this symposium we will explore recent research findings on the multiple impacts of tuberculosis on members of affected households, and discuss how programmers, policy makers and funding agencies can support person-centred tuberculosis screening.

Join us for a webinar exploring the latest updates in TB preventive treatment for individuals exposed to drug-resistant tuberculosis (DR-TB).
In September 2024, WHO released much-anticipated new guidelines on TB preventive treatment (TPT), featuring a strong recommendation for drug-resistant TPT (DR-TPT): a 6-month daily levofloxacin regimen for individuals exposed to multidrug- and rifampicin-resistant TB .
This webinar focused on the evidence behind this new recommendation, addressing both its benefits and potential risks. We discussed community perspectives and the practical challenges of implementing DR-TPT in diverse settings. A panel of global experts offered insights into effective programmatic implementation and highlight areas where further research is needed.

Despite the development of new drugs, and trials to support more effective treatment regimens for TB, cure cannot be achieved without access to medicines. Drug pricing, access policies and patent issues are often responsible for inequalities in getting access to lifesaving medicines to people that need most. Our previous webinar gave an overview of these issues. In this webinar we explored, in-depth, access to Rifapentine. Two talks from experts in the field covered the evidence behind rifapentine's use in TB and unpacked specific barriers to its use.

After decades without new drugs for TB, more options had emerged. Bedaquiline (BDQ) had changed the TB treatment landscape as the first of these new drugs to be licensed for drug-resistant TB. Recent high-profile clinical trials that included BDQ had demonstrated efficacy with few adverse events against MDR/XDR TB, and in shorter regimens for drug-sensitive TB. For the first time in many years, the future had looked bright.
However, there were warning clouds on the horizon. Resistance to BDQ was already present and the capacity to detect it was limited. There was tension between the need for manufacturers to recoup development costs, the ability of those in need to afford the drug, and the global community’s responsibility to preserve its effectiveness for the most resistant cases. Clinicians were faced with difficult questions: how to balance the needs of an individual patient with those of the wider population; whether BDQ should be used for NTM infections where evidence was limited; which clinical trials should be prioritised; and what role BDQ should play in TB preventive therapy given the risks of resistance.
These questions were already being actively discussed and were expected to become more pressing over time. This workshop was therefore convened to explore them, presenting (a) the current situation, (b) possible future scenarios, and (c) perspectives from across the field, including TB survivors, policy experts, and researchers, not only in relation to BDQ but also emerging new drugs.
This expert panel discussion was co-organised by UCL-TB and the Africa Health Research Institute (AHRI; https://www.ahri.org). Participants with an interest in TB were invited to join and contribute to what was intended to be an informative discussion addressing one of the most significant challenges in the field.

Dr Karen Jacobson discussed “Studying substance use in tuberculosis transmission and outcomes in South Africa.”
The impact of infectious diseases on vulnerable populations had been a major concern within UCL, and we were pleased to host an open seminar by Karen Jacobson of Boston University, who had worked in this field for many years.
Her group studied the epidemiology of infectious diseases, with a primary focus on tuberculosis. Working with local and international partners, they combined epidemiological approaches with bacterial and host genetic data, alongside statistical models, to explore questions around TB transmission and outcomes.
She had established a highly productive collaboration with researchers in Cape Town, South Africa, with her work placing particular emphasis on understanding how substance use affected TB transmission and response to therapy.
She was an Associate Professor of Medicine in the Section of Infectious Diseases at Boston University School of Medicine, with a secondary appointment in the Department of Epidemiology at the Boston University School of Public Health.

In order to meet targets to reduce TB incidence, a scale-up of active case finding had been required. Prevalence surveys had repeatedly shown that a significant proportion of people in the community with culture-positive TB did not report symptoms. In 2021, the World Health Organization updated its recommendations for systematic TB screening, emphasising the importance of chest X-ray in identifying these individuals. For the first time, the guidelines also approved the use of Computer Aided Detection to support screening and triage.
A global survey of 63 National TB Programmes, representing over 80% of the global TB burden, had been conducted to better understand current policies, practices, challenges and opportunities in TB screening. This webinar presented the findings of the survey, alongside additional talks that provided context to the results. It was relevant to staff of National TB Programmes, as well as regional and international policymakers, researchers and academics working in this area.

About the Speaker
Professor Di Gibb - Professor of Epidemiology and Programme Leader of the Paediatric Programme of trials and cohorts at MRC Clinical Trials Unit at UCL
Professor Di Gibb is a paediatrician, Professor of Epidemiology and Programme Leader of the Paediatric Programme of trials and cohorts at the MRC Clinical Trials Unit at UCL. Her work on infectious diseases in children has included tuberculosis (TB), HIV, malaria, hepatitis C and antimicrobial resistance.
Di has led numerous international studies, including the recent SHINE trial which was the first randomised controlled trial to assess the length of treatment needed for children with TB, rather than use data on adults. Its demonstration that children with less severe TB disease can be safely treated for four rather than six months has led to changes in WHO policy and implementation.

In July 1921, the first dose of BCG was administered to an infant in a hospital in Paris. One hundred years later, it remained the only available TB vaccine and the most widely used globally, still given to over 100 million children each year.
To mark this milestone, the UCL-TB/Africa Health Research Institute BCG centenary symposium brought together three talks from leading academics, followed by a panel discussion. The event explored the impact of BCG as a vaccine and immunotherapy, what continued to be learned about protection against TB through its study, and the future pipeline for TB vaccines.
Resources
History and current knowledge of clinical use of BCG. Prof Mark Hatherill (Director, South African Tuberculosis Vaccine Initiative (SATVI), University of Cape Town)
BCG, a live, attenuated, bacterial vaccine derived from Mycobacterium bovis, was first administered as vaccine against TB in on 18th July 1921. It remains the only available TB vaccine and is the most widely used vaccine globally still given to > 100 million children each year. This talk will discuss what is known about the impact of BCG vaccination on the prevention of TB infection and disease, the heterogeneity of vaccine efficacy and duration of protection. In addition, it will cover what is understood about the non-TB specific effects of BCG and the role of BCG as cancer immunotherapy.
Professor Mark Hatherill is Director and leader of the clinical research team of the South African Tuberculosis Vaccine Initiative (SATVI), University of Cape Town. A University of Cape Town medical graduate, he trained as a pediatrician and critical care sub-specialist. Since 2005, SATVI has conducted 28 clinical trials of nine novel TB vaccine candidates involving almost 6,000 participants, in addition to large epidemiological and immunological cohort studies. Prof Hatherill played a lead role in efficacy trials that tested the candidate vaccine MVA85A for prevention of TB disease in infants; BCG revaccination for prevention of M. tuberculosis infection in adolescents; and the candidate vaccine M72/ASO1E for prevention of TB disease in adults. He is Co-PI of the Regional Prospective Observational Research in Tuberculosis South Africa consortium. His current work focuses on the design and implementation of clinical trials of novel TB vaccines and biomarker-targeted TB prevention.
Lessons learned about protective immunity from IV BCG in non-human primates. Dr Trish Darrah (Vaccine Research Center, National Institute of Allergy and Infectious Diseases, NIH)
As intradermal (ID) BCG administered at birth has variable efficacy in preventing pulmonary TB in adults, a major goal of our work is to investigate alternative routes of vaccination that may elicit cellular immunity in the lung sufficient to protect against TB disease. We recently published that BCG given intravenously (IV) elicited robust lung-resident T cell responses and provided a high level of protection against infection and disease compared to the same dose of BCG given ID or by aerosol. These data establish a benchmark of protection in a highly susceptible rhesus macaque model and provide an opportunity to study immune correlates and mechanisms of protection to facilitate proof-of-concept studies in humans.
Dr Patricia Darrah received her PhD in Microbiology & Immunology from Temple University School of Medicine in 2001. Since then, she’s worked in the Cellular Immunology Section of the NIH Vaccine Research Center studying how various vaccine platforms shape the magnitude, quality, breadth, and tissue distribution of CD4 and CD8 T cell responses after immunization. Tricia currently leads the VRC TB Unit under Robert Seder & Mario Roederer, investigating the immunogenicity and efficacy of new vaccines against tuberculosis in a pre-clinical nonhuman primate model.
BCG revaccination – how does this fit within the TB vaccine development pipeline? Dr Alex Schmidt (Head of Vaccine Development, Bill & Melinda Gates Medical Research Institute)
BCG vaccination is the cornerstone of TB prevention in infants and children, but the role of BCG revaccination of older children and adolescents is less clear. A recent trial in South Africa observed a 45% reduction in sustained IGRA conversion (a marker suggesting ongoing Mtb infection) in children who received a second dose of BCG as adolescents. Does this indicate that BCG revaccination could contribute to prevention of TB disease in adolescents and young adults? What data is needed to make informed policy decisions on BCG revaccination? Could BCG revaccination be part of the global End TB strategy? How do other vaccines in development compare to BCG revaccination?
Dr Alex Schmidt serves as Head of Vaccine Development at the Gates MRI. He joined Gates MRI in 2018 after seven years with GSK Vaccines, where he led vaccine development programs for dengue, RSV and influenza virus vaccines. Prior to GSK, Alex spent 10 years in the NIH intramural program, where he led a lab-based team and worked on translational and clinical development for viral vaccines.
