ArticlePublication 2017Using Data-Driven Agent-Based Models to Forecast Emerging Infectious Diseases
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which …
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which was subsequently used in the Ebola forecasting challenge. Producing timely and reliable forecasts for an epidemic of an emerging infectious disease is a challenge. Epidemiologists and policy makers have to deal with poor data quality, limited understanding of the disease dynamics, a rapidly changing social environment and the uncertainty around the effects of various interventions in place. In this setting,…

ArticlePublication 2013Estimated Mortality Impact of Vaccinations 2011–2020 in 73 GAVI Alliance Countries
From August to December 2011, a multidisciplinary group with expertise in mathematical modeling was constituted …
From August to December 2011, a multidisciplinary group with expertise in mathematical modeling was constituted by the GAVI Alliance and the Bill & Melinda Gates Foundation to estimate the impact of vaccination in 73 countries supported by the GAVI Alliance. The number of deaths averted in persons projected to be vaccinated during 2011–2020 was estimated for ten antigens: hepatitis B, yellow fever, Haemophilus influenzae type B (Hib), Streptococcus pneumoniae, rotavirus, Neisseria meningitidis serogroup A, Japanese…

ArticlePublication 2024Hepatitis C Elimination in Rwanda: Progress, Feasibility, Economic Evaluation
This study evaluates the impact of Rwanda's national program launched in 2018 to eliminate hepatitis …
This study evaluates the impact of Rwanda's national program launched in 2018 to eliminate hepatitis C virus (HCV) and identifies strategies to achieve World Health Organization (WHO) elimination goals by 2030. Employing a microsimulation model spanning 2015 to 2050, the analysis assesses HCV epidemic trends, prevalence, mortality, and total care costs under various scenarios. Results show that between 2018 and 2022, over 7 million people were screened and 60,000 treated, projecting Rwanda's potential achievement of…

ArticlePublication 2021Health Gains and Financial Protection from HPV Vaccination
High out-of-pocket medical expenses for cervical cancer can lead to catastrophic health expenditures and medical …
High out-of-pocket medical expenses for cervical cancer can lead to catastrophic health expenditures and medical impoverishment in many low-resource settings. This article uses a static cohort model that captures the main features of HPV vaccines and population demographics to project health and economic outcomes associated with routine HPV vaccination in Ethiopia. The findings show that, assuming 100% vaccine efficacy against HPV-16/18 and 50% vaccination coverage, routine HPV vaccination could avert up to 970 000 cases…

ArticlePublication 2022Re-Evaluating the Health Impact and Cost-Effectiveness of Tuberculosis Prevention for Modern ART Cohorts
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in …
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in HIV-infected individuals receiving antiretroviral therapy (ART). However, as individuals initiate ART earlier in the course of disease, TB incidence is lower, and it is unclear how ART cost-effectiveness has changed. This study assessed the cost-effectiveness of TPT in contemporary ART cohorts. The authors developed a microsimulation model of TB and HIV and parameterised it using data from a large HIV…

ArticlePublication 2021Measuring the Impact of COVID-19 Vaccine Misinformation on Vaccination Intent in the U.K. and U.S.
Widespread acceptance of a vaccine for SARS-CoV-2 will be the next major step to fight …
Widespread acceptance of a vaccine for SARS-CoV-2 will be the next major step to fight the COVID-19 pandemic, but high uptake achievement will be a challenge and may be impeded by online misinformation. This article is a randomized controlled trial in the U.K. and the U.S. with the objective to quantify how exposure to online misinformation around COVID-19 vaccines affects intent to vaccinate to protect oneself or others. The authors report that in both countries…

ArticlePublication 2017Revealed Willingness-to-Pay vs. Standard Cost-Effectiveness Thresholds
This study estimates the cost-effectiveness thresholds (CETs) of 16 HIV programs in South Africa. The …
This study estimates the cost-effectiveness thresholds (CETs) of 16 HIV programs in South Africa. The use of CETs based on a country’s income per capita has been criticized for not being grounded in theory or evidence, especially in low and middle-income countries (LMICs). An alternative has been produced for South Africa, based on estimates of life years saved and the country’s committed HIV budget. The authors used a previously -published optimization method to estimate CETs,…

ArticlePublication 2017Predicting Carer Health Effects for Use in Economic Evaluation
Illnesses and interventions can affect the health status of family carers in addition to patients. …
Illnesses and interventions can affect the health status of family carers in addition to patients. However economic evaluation studies rarely incorporate data on health status of carers. In order to investigate whether changes in carer health status could be ‘predicted’ from the health data of those they provide care to, as a means of incorporating carer outcomes in economic evaluation, the authors used regression models to analyse changes in carers’ health status. They derive predictive algorithms based on…

ArticlePublication 2017Estimated Economic Impact of Vaccinations in 73 LMIC, 2001-2020
This analysis estimates the economic impact likely to be achieved by efforts to vaccinate against 10 …
This analysis estimates the economic impact likely to be achieved by efforts to vaccinate against 10 vaccine-preventable diseases between 2001 and 2020 in 73 low- and middle-income countries largely supported by Gavi, the Vaccine Alliance. The authors used health impact models to estimate the economic impact of achieving forecasted coverages for vaccination against Haemophilus influenzae type b, hepatitis B, human papillomavirus, Japanese encephalitis, measles, Neisseria meningitidis serogroup A, rotavirus, rubella, Streptococcus pneumoniae and yellow fever. In…
