Extract from report of GACVS meeting of 30 November-1 December 2016, published in the WHO Weekly Epidemiological Record of 13 January 2017
The Committee was presented with an update of research on the association of adjuvanted p2009HN1NI influenza vaccines and narcolepsy. During the influenza pandemic of 2009, oil-in-water emulsion adjuvants (AS03 and MF59) were used in vaccines to maintain immunogenicity when antigen availability was limited and dose sparing was required. As was noted previously by GACVS in the meeting report of December 2015,4 there is consistent evidence in Europe of an increased risk of narcolepsy following use of Pandemrix, despite the varying datasets and methods used. New research was presented from a multicountry study sponsored by the United States Centers for Disease Control and Prevention.5
