I haven't thought of that before, but I know that at UNICEF we're always working with governments, because ultimately members of the United Nations, member states, are on our board of directors—from that level. But we are also all the time working with ministries of health.
I think that's a good idea, but I don't know what has been done. Clearly, there are good lessons to be learned. In some countries, it works, but you need the politicians and the senior public servants ready to make it work.
