A systematic review of national immunization policy making processes.

This systematic review aimed to collect and synthesize information available on immunization policy making processes in countries across the globe. Twenty-nine published articles and five websites in either English or French provided varied information on the immunization policy making processes in 33 countries. The information retrieved varied from players involved to types of evidence used when making immunization policies. Fourteen countries reported the presence of a National Immunization Technical Advisory Group (NITAG), an advisory body that provides immunization recommendations to the national government to facilitate their policy making. In conclusion, there is relatively limited information available on immunization policy making processes at the national level.
