“…Even more surprising in a country where as a result of the inaccurate or false attribution of side-effects to polio vaccines, some groups persistently still refuse polio vaccination [21]. This neglect may reflect that the effectiveness and cost-effectiveness of efforts to increase demand is still uncertain [48].…”

“…The downward trend in polio incidence in Chad was reverted since wild poliomyelitis virus was imported from Nigeria in 2001, with cases of poliomyelitis still occurring every year [10, 16–19, 21, 22]. The on-going efforts towards polio eradication lead to high primary care workloads, requiring an intense mobilization of health workers, limiting their availability for routine immunization activities [23].…”

IntroductionChad is one of the countries supported by the GAVI-Alliance that remains with unsatisfactory vaccination coverage. This paper tries to understand the main barriers to better coverage.MethodsThese barriers were categorised as up or downstream against the health system building blocks as proposed by WHO and compared with barriers and activities identified by the country in its health system's strengthening grant proposal as approved by the GAVI Alliance in 2007. Data were collected using a modified Delphi system and by analysis of grant and annual report documents.ResultsMost of the activities anticipated under the GAVI health system's strengthening proposal are activities targeting downstream barriers (the neglect of upstream issues is of major importance in a decentralised state like Chad) and aligned with, not complementary to, immunization services strengthening activities. Further, both set of cash grants are blind to important recommendations such as the need to address barriers at the level of leadership and governance and at the level of the financing system and also about initiatives to promote community demand of vaccination services.ConclusionIn Chad slow vaccination progress is aggravated by several contextual barriers: the size of the country, the low population density, the nomadic nature of a significant part of its peoples, the recent civil war, associated with civil unrest and political instability and its geographical localization. In this situation it would be important to sustain downstream operations (the major focus of the ISS grant) while taking a long term view of the needs of the health system. The GAVI effectively supports downstream operations, but neglects the long term view.
