MSA’s Rachel Glennerster and Siddhartha Haria with Saloni Dattani have a new essay out in Works in Progress: “Why we didn’t get a malaria vaccine sooner”.  In addition to covering the long journey to a malaria vaccine, it explains why commercial markets may neglect diseases that mainly affect the poor and how Advance Market Commitments (AMCs) can help.  It discusses why we didn’t get an AMC for a malaria vaccine and some of the dilemmas involved with market shaping.
