National Immunization Technical Advisory Groups (NITAGs): guidance for their establishment and strengthening

The majority of industrialized and some developing countries have formally established national technical advisory bodies to guide immunization policies; other countries are working towards or contemplating the establishment of such bodies. These advisory bodies are often referred to as National Immunization Technical Advisory Groups (NITAGs). A NITAG is a technical resource supplying guidance to national policy makers and programme managers to enable them to make evidence-based immunization related policy and program decisions. The focus of this paper is to: (1) review the value and functions of a NITAG; (2) provide directions and identify issues for countries to consider when establishing or improving the functioning of a NITAG; and (3) outline potential WHO and partners' roles and activities in support of the establishment and strengthening of NITAGs.
