In a nutshell Vitamin A supplementation (VAS) is the mass distribution of vitamin A capsules to preschool-age children to reduce child mortality.

In a nutshell Seasonal malaria chemoprevention (SMC) involves giving children monthly courses of antimalarial medicines during the high malaria season (in places where malaria is seasonal). We estimate that it costs approximately $2,000 to $7,000 (depending on the location) to avert a death in areas where GiveWell supports SMC. We think SMC is cost-effective because we think:| GiveWell
We feel that international aid can be an extremely good option for a donor; but it also comes with serious risks that projects will accomplish no good, or will even cause harm. Below we present several broad ways in which an international aid project can fail, and some examples of when they have. Poorly executed programs Well-intended projects can fail if they're not well suited to local conditions, or are otherwise poorly carried out.| GiveWell

Summary GiveWell enables some staff to recommend a certain amount of funding annually via "small discretionary grants." We believe that we can increase our expected impact by occasionally funding small, promising opportunities without investing a lot of time in evaluating them. These small discretionary grants will make up a very small portion of the total funding we direct each year. More details follow.| GiveWell

Charities' fundraising materials make it seem obvious that their programs are changing lives. Are charities really accomplishing what they say they are? Are they making a difference? Conventionally, most people expect that charities are probably accomplishing good unless there's proof that money is being misappropriated. We disagree. We think that charities can easily fail to have impact, even when they're doing exactly what they say they are.| GiveWell
