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

Part of Change 2.0

Actionable market intelligence, including vaccine demand forecast/scenarios, generated to strategically guide manufacturers and partners in their planning for introduction in high burden countries. The objectives include: 1. Strategic assessment of appropriate market-shaping interventions, 2.Stakeholder and decision process mapping , 3.Demand dynamics understanding and realistic market forecast development, 4. Commercialization strategy support for lead candidate(s).

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

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

Epidemiologic study to assess the IGRA positivity in populations with a high TB

Tuberculosis (TB) vaccine efficacy trials evaluating prevention of disease must be feasible in size and duration and would ideally take place at clinical trial sites that enroll from communities with the highest incidence rates. In preparation for the Phase 3 trial of the investigational M72/AS01E-4 vaccine, we conducted a multi-country study, using interferon gamma release assay (IGRA) positivity as a proxy for expected incidence of TB. In addition to the above objects, the results from this study could help in in new vaccine introduction to identfy TB hotspot areas.
