Facing up to reality? What to do if M72/AS01E doses are limited

The Ph3 trial for the vaccine candidate M72/AS01E is underway, and, assuming a positive result, could be licensed by 2030. Modelling suggested a large potential impact from introducing M72/AS01E but assumed an unconstrained dose supply. However, at least initially, it is likely that M72/AS01E will be supply-constrained. We estimated the effect of decisions surrounding the allocation of constrained doses on the potential global impact of M72/AS01E

Advancing evidence-informed in-country decision-making for new TB vaccine introduction: A responsive and integrated vaccine modelling approach from India

As new TB vaccines move into late-stage development, it is imperative for high-burden countries like India to ensure timely and effective evidence-generation to inform decision-making and accelerate vaccine development and introduction. To enable this, an in-country vaccine mathematical modelling effort has been initiated in India.

TBVacMod

Estimate the health impact of introducing a prevention of disease vaccine for adult and adolescents in moderate to high TB burden countries. Explore different vaccine introduction scenarios based on input from country stakeholders, including national TB program and immunization program officials, on priority groups for vaccination and likely vaccine coverage. The project's key questions include: 1) who are the priority groups in different countries and what is expected level of vaccine coverage in those groups 2) how will vaccine impact differ in different introduction scenarios (vary age, priority group, coverage)

FAST-TB MOD

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.

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

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.

Prep4TBVax

New TB vaccines are likely to be crucial in addressing the ongoing TB pandemic. With multiple promising vaccine candidates in the pipeline and the earliest availability of a candidate expected by 2028, it is of outmost importance that once available, the vaccine can be implemented rapidly and effectively. Limited research has looked at the delivery strategies available to provide a new TB vaccine to beneficiaries and therefore, this study assesses the acceptability and feasibility of delivery strategies for the vaccine candidates M72/AS01e and MTBVAC in Ethiopia, Nigeria, and Tajikistan.
