It is important to note, however, that no matter how or if they change, UN agencies and other global entities can only be as useful as individual governments allow them to be. The agencies serve the governments, which have ultimate responsibility for overseeing service provision for their citizens. Global partners can and should offer extensive support to governments that show a clear interest in developing realistic policies and programmes to reduce vertical transmission. An example of potentially useful process would be to have Country Coordinating Mechanisms (CCMs) and National AIDS Councils work closely together to assess barriers to care utilization.
