The potential epidemiological impact of preventive HIV vaccines on the HIV epidemic in Southern India is examined using a mathematical deterministic dynamic compartmental model. Various assumptions about the degree of protection offered by such a vaccine, the extent of immunological response of...

This study assesses the potential demand by the public sector for a preventive HIV/AIDS vaccine in Brazil and the costs of alternative strategies for a vaccination program. Brazil has a mature AIDS epidemic: the percent of the population living with HIV or AIDS (about 0.6 percent of adults) is...

Even a modestly effective HIV-1 vaccine would be highly useful in India and could avoid millions of deaths. How should such a vaccine be introduced? Based on evidence of adoption of other vaccines in India, current levels of spending on them and coverage of prevention programs targeting both...

The authors delineate two different algorithms for the purchase of AIDS vaccines, to show how differences in policy objectives can greatly affect projections of the number of courses of vaccine that will be needed. They consider a hypothetical vaccine costing ten dollars to produce, and offering...

Many people see an effective preventive AIDS vaccine as the best solution to the HIV/AIDS pandemic. Ten years ago many scientists had hoped that a vaccine would be available by now. Most scientists are still optimistic that vaccines will be developed and many candidates are being tested....

HIV prevalence in Southern Africa is the highest in the world and the impact of HIV/AIDS in the region are devastating at all levels of society, including the wider economy. Government response has lagged behind the pace of the epidemic, but programs are now beginning to focus on a broad range...

The author tests the hypothesis that education improves health and increases people's life expectancy. Smoking histories-reconstructed from retrospective data in the National Health Interview Surveys in the United States-show that after 1950, when information about the dangers associated with...

HIV-prevention strategies have yielded only limited success so far in slowing down the AIDS epidemic. This paper examines novel intervention strategies that use incentives to discourage risky sexual behaviors. Widely-adopted conditional cash transfer programs that offer payments conditioning on...

A growing number of developing countries have introduced conditional cash transfer programs that provide money to poor families with certain contingencies attached - such as requiring school attendance or regular immunization and health check-ups. As the popularity of conditional cash transfer...

The AIDS epidemic is dramatically increasing mortality of adults in many Sub-Saharan African countries, with potentially severe consequences for surviving family members. Until now, most of these impacts had not been quantified. The authors examine the impact of adult mortality in Tanzania on...
