Willingness to receive a future TB vaccine among pregnant women living in Brazil, Ghana, Kenya, and Pakistan

Our study assessed the willingness of pregnant women across four countries - Brazil, Ghana, Kenya, and Pakistan to receive a future TB vaccine.

Insights into TB vaccine acceptability among adolescents in Khayelitsha through community engagement

Ongoing

Initially designed as an internal assessment of the impact of engagement workshops, we used short surveys to understand high-school learner perspectives of vaccines, focusing on COVID 19, TB and HIV vaccines. Between 2022 and 2024, we collected responses from 350 adolescents (14-18 years old). All participants live in Khayelitsha, where high rates of TB (4224 cases notified in the last year) intersect with socio-economic challenges

Modelling to estimate the health impact of novel tuberculosis vaccines on TB burden in people living with HIV

2023-2024

Hypothetical vaccine

Ongoing

This project will inform tuberculosis (TB) prevention efforts by estimating the health impact of novel tuberculosis vaccines on TB burden in people living with HIV (PLHIV) using a novel Mycobacterium tuberculosis transmission model. HIV confers the largest relative risk of TB, and new TB vaccines could be an important tool to prevent TB; however, modelling studies have not systematically investigated how new vaccines will affect TB burden in PLHIV. In stage 1 of this project, we aim to investigate TB vaccine impact in PLHIV where vaccine product characteristics and delivery vary by recipient HIV status. In stage 2, we aim to quantify how complex vaccine targeting strategies and incorporating additional granularity in HIV/AIDS natural history might affect vaccine impact estimates in PLHIV

New tuberculosis vaccines are in late-stage trials, but how confident is the public in high burden countries in vaccines?

Ongoing

With tuberculosis (TB) vaccine candidates in late-stage trials, it is important to prepare for implementation to avoid delays upon licensure. General confidence in vaccines has been identified as an anticipated barrier to introducing new TB vaccines. In the absence of detailed TB specific vaccine acceptability and confidence data, we analysed currently available vaccine confidence data in countries appearing on one of the World Health Organization (WHO) high burden lists to investigate vaccine confidence in countries with a high TB burden

FAST-TB MOD

2023-2026

Hypothetical vaccine

Ongoing

FAST-TB population and cost-effectiveness modelling core: This project will accelerate tuberculosis (TB) research translation by using mathematical modelling to address key priority questions as part of FAST TB, linking an expanded state-of-the-art modelling framework with country level data and cross consortium communication around new TB treatment regimens, diagnostics and other interventions.

Preparing the landscape for TB vaccines: South Africa’s strategic planning

Ongoing

The South African TB Think Tank is a national collaboration of TB stakeholders, including researchers, policymakers, clinicians, and civil society. Chaired by the Chief Director of the National TB Programme (NTP), members consolidate TB research through several technical task teams, providing evidenced-based policy recommendations to the Department of Health. To support the national TB vaccine initiative, the TB Think Tank provided recommendations for the recently released NTP Strategic Plan, 2023-28

Creating evidence to support tuberculosis (TB) national and global decision-makers in reducing the global burden of TB

2024-2028

Hypothetical vaccine

Ongoing

In strong collaboration, we (India, South Africa, Brazil, Indonesia, UK) will create evidence to strengthen capacity and sustainably support high tuberculosis (TB) burden countries (HBC) and global decision-makers in reducing the global burden of TB, by using modelling tools to address key questions on drug-resistant (DR-)TB, new TB vaccines and other interventions, and extend and apply a state-of-the-art TB model, to estimate the relative health, cost-effectiveness, and budget impact, of new and existing interventions, as well as their optimal combination.

Forecasting TB vaccine demand to support supply and procurement planning

Ongoing

We present insights from two workshops with global health funders, academics, and in country TB and vaccine decision-makers and estimates of potential global demand for TB vaccines using a bottom-up, constrained demand forecasting model. The model was informed by the workshops, publicly available target product profile, landscape assessment of vaccines in development, information from proxy vaccines sourced from the WHO databases and peer reviewed literature, and interviews with TB and vaccine experts

Perceptions of the incarcerated population regarding tuberculosis research and vaccines

Ongoing

A qualitative study that aims to understand to perceptions and attitudes regarding TB, TB vaccines, and participation in TB vaccine trials among persons deprived of liberty (PDR) in Brazil.

Financing and policy innovation to advance TB vaccines through licensure: A G20 policy proposal

Ongoing

The authors developed two T20 policy briefs proposing recommendations to enhance G20 leadership and bring TB vaccines through licensure: Investment Toolbox to Advance TB Vaccine R&D through Joint Action (2023); and Elevating Leadership of HBC G20 States in TB Vaccine R&D and Delivery (2024). The briefs were informed by extensive literature research and aligned with global initiatives for TB and TB vaccine R&D.
