A report of the safety and surveillance working group


The Global Advisory Committee on Vaccine Safety (GACVS), an independent expert clinical and scientific advisory body, provides WHO with scientifically rigorous advice on vaccine safety issues of potential global importance. GACVS held its 34th meeting in Geneva, Switzerland, on 15–16 June 2016. The Committee examined 3 generic issues: (i) a new initiative to promote health product vigilance in low- and middle-income countries (LMICs); (ii) the harmonization of the definition of health events for pharmacovigilance studies in pregnancy and early childhood; and (iii) a proof-of-concept study to assess rare events through multicountry collaboration. The Committee also reviewed vaccine-specific safety issues on routine infant vaccination in India and initial post-licensure data related to dengue vaccine.
