Population-level health and economic impacts of introducing Vaccae vaccination in China: a modelling study

Is neglect of self-clearance biasing TB vaccine impact estimates?
exploring the inclusion of self-clearance in models of tuberculosis affects the estimates of vaccine impact in China and India
Bridging the gap: evaluating high TB burden country data needs to support the potential introduction of TB vaccines for adolescents and adults: a workshop report
A workshop to asked high TB burden country experts about what epidemiological, impact, feasibility and acceptability data they anticipated they would need to guide TB vaccine introduction.
Estimating the potential public health value of BCG revaccination
Using previously calibrated models for India and South Africa, we simulated BCG revaccination assuming 45% prevention-of-infection efficacy, and we evaluated scenarios varying additional prevention-of-disease efficacy between +50% (reducing risk) and −50% (increasing risk).
Meeting the 2030 End TB goals in the wake of COVID-19: a modelling study of countries in the USAID TB portfolio.
From 2023 onwards we modelled a combination of interventions acting at different stages of the care cascade, including improved diagnostics; reducing the patient care seeking delay; and the rollout of a disease-preventing vaccine from 2025 onwards.
Modelling the global burden of drug-resistant tuberculosis avertable by a post-exposure vaccine
Using mathematical models, we seek to estimate the potential impact of a post-exposure TB vaccine, having 50% efficacy in reducing active disease, on global rifampicin-resistant (RR-) TB burden.
Estimating the epidemiologic impact of new TB vaccines in high-burden settings
This is an NIH-funded study which will estimate the health impact of introducing a prevention of disease vaccine for adult and adolescents in moderate to high TB burden countries. We are developing model scenarios based on input from country stakeholders, including national TB program and immunization program officials.
Formative work to understand factors affecting future TB vaccines acceptance and readiness
This project aims to collect data to: 1) Assess health facility and health systems readiness for a new TB vaccine, and 2) Explore decision-making factors for new TB vaccine demand and acceptance
A global framework to prepare for country introduction of new TB vaccines for adults and adolescents
New vaccines for the prevention of TB disease in adolescents and adults could become available in the next 3-5 years. WHO has therefore developed a Global Framework to prepare for Country Introduction of New TB Vaccines for Adults and Adolescents which aims to guide countries and global stakeholders in preparing for the introduction and scale-up in countries. This framework has been drafted in collaboration with a WHO Expert Advisory Group and in consultation with other stakeholders, and describes critical activities to prepare for introduction decision-making and subsequent implementation and impact of new TB vaccines for adults and adolescents.
