The Toto Foundation, a non-profit arm of a drone company, seeks to deploy drone technology for aid projects in Africa. With a $4 million upfront grant and $1 million annually, they aim to maximize impact on human lives. Analysis of potential projects reveals vaccine and general medicinal delivery as the most promising option. Further evaluation of target countries considers factors like vaccination rates, poverty levels, and safety. Senegal and Guinea emerge as prime candidates. Detailed cost and impact calculations show Senegal as the optimal choice, capable of delivering 300,000 vaccine vials annually compared to Guinea’s 120,000. The recommendation is to launch the vaccination delivery service in Senegal, with considerations for pilot programs, infrastructure development, regulatory approval, and partnership expansion.
