Consider his foundation’s approach to malaria, which focuses on bed nets, a low-tech, only modestly effective intervention, and on the development of a vaccine, a high-tech solution that has eluded intensive efforts for decades. This approach dismisses an old, cheap, and safe way to control the vector – the Anopheles mosquito – that spreads the disease: the chemical DDT.
看看他的基金会应对疟疾的方法：在低技术层面上专注于使用蚊帐，一种有一定效果的干预方式；在高技术层面上，则顷力研发疫苗，费时数十载却无斩获。这种方法排除了一种古老、廉价又安全的控制病媒疟蚊的举措：化学农药滴滴涕(DDT)。
