“Are our Top Charities saving the same lives each year?” by GiveWell

This is a link post. Author: Adam Salisbury, Senior Research Associate In a nutshell We’ve had a longstanding concern that some of our top charity programs, including insecticide-treated nets, seasonal malaria chemoprevention (SMC), and vitamin A supplementation (VAS), may have less impact than we've estimated due to “repetitive saving.” These programs provide health interventions to the same children under 5 years old annually or every 3 years. Our cost-effectiveness models currently assume that different lives are saved each year from these interventions. We think it's possible the programs are actually saving the same, high-risk children over and over. In a worst-case scenario, this could mean the programs are saving 80% fewer cumulative lives than we thought.
