My friend Jacqueline tells the story of how Unicef spent a fortune creating posters to promote the idea of child vaccination to the mothers of Rwanda. “The posters were gorgeous—photographs with women and children with simple messages written in Kinyarwandan (the local language), about the importance of vaccinating every child. They were perfect, except for the fact with a female illiteracy rate exceeding 70 percent, words written in perfect Kinyarwandan made little difference.”
