Can a business serve both its shareholders and the public good?

One of those companies is GlaxoSmithKline, which has joined with the Bill and Melinda Gates Association in the pursuit to develop a malaria vaccine for children in Africa. In an in-depth interview with The Wall Street Journal, CEO Andrew Witty discusses the latest developments in vaccine research and how businesses can make a profit – and serve the public good.
