ArticlePublication 2014Rise and Fall of HIV in High-Prevalence Countries: A Challenge for Mathematical Modeling
Several countries with generalized, high-prevalence HIV epidemics, mostly in sub-Saharan Africa, have experienced rapid declines …
Several countries with generalized, high-prevalence HIV epidemics, mostly in sub-Saharan Africa, have experienced rapid declines in transmission. These HIV epidemics, often with rapid onsets, have generally been attributed to a combination of factors related to high-risk sexual behavior. The subsequent declines in these countries began prior to widespread therapy or implementation of any other major biomedical prevention. This change has been construed as evidence of behavior change, often on the basis of mathematical models, but…

ArticlePublication 2013Validation and Calibration of a Simulation Model of Pediatric HIV Infection
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of …
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model framework. This CEPAC-Pediatric model was then validated by varying CD4 data and comparing the corresponding model-generated survival curves to empirical survival curves obtained from the International Epidemiologic Database to Evaluate AIDS (IeDEA). The model was calibrated to other African countries by systematically varying immunologic and HIV mortality-related input parameters. In the calibration analyses, the model-generated…

ArticlePublication 2013Public Finance of Rotavirus Vaccination in India and Ethiopia: Extended CEA
This study uses extended cost-effectiveness analysis (ECEA) to evaluate a hypothetical publicly financed program for …
This study uses extended cost-effectiveness analysis (ECEA) to evaluate a hypothetical publicly financed program for rotavirus vaccination in India and Ethiopia. The authors measured program impact on: (1) averted rotavirus deaths; (2) reduction in household expenditures; (3) financial risk protection; and (4) distributional consequences across the country’s wealth strata. In India and Ethiopia, the program was predicted to decrease rotavirus deaths substantially, and effectively provide financial risk protection among the poor, while also reducing household…

ArticlePublication 2011Health and Economic Impact of HPV 16/18 Vaccination and Cervical Cancer Screening in Eastern Africa
In this article the authors use epidemiologic data from Kenya, Mozambique, Tanzania, Uganda, and Zimbabwe …
In this article the authors use epidemiologic data from Kenya, Mozambique, Tanzania, Uganda, and Zimbabwe to develop models of HPV-related infection and disease. For each country, they assessed HPV vaccination of girls before age 12 followed by screening with HPV DNA testing once, twice, or three times per lifetime (at ages 35, 40, 45). For women over age 30, they assessed only screening (with HPV DNA testing up to three times per lifetime or VIA…

ArticlePublication 2010Health and Economic Impact of Rotavirus Vaccination in GAVI-Eligible Countries
Rotavirus infection is responsible for about 500,000 deaths annually, and the disease burden is disproportionately …
Rotavirus infection is responsible for about 500,000 deaths annually, and the disease burden is disproportionately borne by children in low-income countries. Motivated by the global recommendation by the WHO that all countries include infant rotavirus vaccination in their national immunization programs, the objective of this analysis was to provide information on the expected health, economic and financial consequences of rotavirus vaccines in the 72 GAVI support-eligible countries. The authors synthesized population-level data from various sources (primarily from…

ArticlePublication 2007Economic Evaluation of Hepatitis B Vaccination in Low-Income Countries: Cost-Effectiveness Affordability Curves
In the face of uncertainties about both the health and economic consequences of a vaccine …
In the face of uncertainties about both the health and economic consequences of a vaccine program, as well as the availability and magnitude of resources needed to fund the program, cost-effectiveness affordability curves can provide information to decision-makers about the probability that a program will be both cost-effective and affordable: these are distinct but equally relevant considerations in resource-poor settings. This paper describes the application of this method to assess a hepatitis B vaccination program in the…
