Author summary Why was this study done? Most individuals who develop tuberculosis (TB) are working age adults living in low- and middle-income countries (LMICs), and the resulting disability and death impact economic productivity and burden health systems, but new TB vaccine candidates may reduce this burden. Earlier studies have estimated the impact of individual diseases and health risks on rates of economic growth, but the potential gains to economic growth that could be produced by introducing novel TB vaccines have not been previously estimated. What did the researchers do and find? In this study, we estimated the impact of introducing novel TB vaccines on gross domestic product (GDP) growth in 105 LMICs, using a macroeconomic model to simulate country-level GDP trends between 2020 and 2080, in 2020 US dollars. We compared scenarios for introduction of infant and adolescent/adult vaccine candidates to a no-new-vaccine counterfactual. Compared to the no-new-vaccine counterfac
In a modelling study, Dr. Allison Portnoy and colleagues explore the cost and cost-effectiveness of novel tuberculosis vaccines in low- and middle-income countries.
