Nigeria’s ex finance minister, Ngozi Okonjo-Iweala,  has secured an appointment with US investment bank Lazard’s sovereign advice division. She has also been appointed chair-elect of the board of Gavi, the Vaccine Alliance, founded by Bill and Melinda Gates.

“The two appointments I’m going to undertake embody a continuation of what I’ve tried to do in my career. My work at Gavi will help me continue my work in strengthening institutions and building systems, to improve the health of children through immunization.” The renowned Nigerian economist said.
