A new vaccine could help eliminate the disease. What would that mean for African economies?

Manuela Saragosa speaks to the man who led the team behind the new vaccine, which has demonstrated a startling 77% effectiveness in recent drug trials. Adrian Hill of Oxford University's Jenner Institute says it is the culmination of 20 years' work - but how was it all funded?

Research suggests malaria has been one of the biggest factors that historically held back African economies, according to Obinna Onwujekwe, professor of health economics at the University of Nigeria. But the big pharmaceutical companies have had no commercial interest in developing a vaccine, says Els Torreele of University College London.
