There were no reports of NITAGs which had been in existence but were no longer functioning. Generally,

the NITAGs in each country provided advice and guidance to the government on the administration of vaccines to the population. For example, the terms of reference for the Australian NITAG are to provide technical advice on the administration of vaccines available in Australia, advise on and assess the evidence available on existing, new and emerging vaccines, produce the Australian Immunization Handbook, and consult with partners Selleck Alpelisib on matters relating to the implementation of the Australian Immunization Program [33]. It

is unknown when most of the NITAGs were established, as the dates of the creation of the NITAGs were only provided for 5 of the 14 countries. The NITAG in the UK was established in 1963 [24] and [36], Canada [34] and the USA [25] in 1964, France in 1997 [32], and Switzerland in 2004 [32]. Although the exact year is not reported, the NITAG in New Zealand has existed since at least 1980 [30]. Of the 14 countries for which information on their NITAGs was retrieved, 12 countries provided information on their membership (all except Brazil and New Zealand) [13], [16],

[17], [24], learn more [25], [32], [34], [36] and [37]. The number of members was reported for 8 of the NITAGs and varied from 12 to 17 (Austria, Canada, France, Germany, Ireland, Switzerland, the UK, the USA) [16], [17], [24], [25], [32], [34], [36] and [37]. Five of the countries reported that a defined term is given for members which lasts three to four years (Austria, very Canada, Switzerland, the UK, the USA) [17], [25], [32], [34], [36] and [37] while the reports for Italy and Spain indicated that there is no defined term limit for committee members [32]. The chair of the committee is referred to for three of the NITAGS: Canada, France, and the USA [22], [32] and [37]. There were between 4 and 15 ex-officio members reported by 5 of the committees [16], [24], [25], [32], [33], [34], [36] and [37] and between 11 and 27 liaison members reported by two committees [16], [25], [34] and [37]. All members on the NITAGs in Canada, the UK, and the USA must declare potential conflicts of interest [25], [34], [36] and [37]. In the case of a conflict of interest, the member may be excluded from the final decision making [34], [36] and [37] or if the conflict is significant, they may have to resign [25].
