Report of the Sage Working Group on Vaccine Hesitancy

World Health Organization (WHO). Report of the Sage Working Group on Vaccine Hesitancy. 2014.

Unlike other medicines, vaccines work at both the individual and community level. While no vaccine is 100% effective, when used broadly in communities, several vaccine preventable diseases could be eliminated and some may be eradicated. High vaccine uptake rates, specific to each vaccine preventable disease, are needed for community-level immunity to be achieved and sustained in order that disease risk can lowered beyond what would be predicted by vaccine coverage alone. Even in countries with overall high national vaccine uptake rates, there may be clustered pockets or subgroups where the rates of uptake are lower than required for protection of the community. In the past decade, such pockets have been associated with outbreaks or resurgence of measles, mumps, Haemophilus influenzae b, pertussis and polio in countries where these diseases had previously been controlled.

At the November 2011 meeting of the Strategic Advisory Group of Experts (SAGE) on Immunization, SAGE noted with concern the impact of reluctance to accept immunization on the uptake of vaccines reported from both developed and developing countries. These reports led SAGE to request the establishment of a working group on vaccine hesitancy.
