[Evaluation of introduction of the Haemophilus influenzae vaccine in Côte d’Ivoire].

Introduction: Côte d’Ivoire introduced the Haemophilus influenzae type b vaccine into the EPI in March 2009. Following this introduction, an evaluation was conducted in 2012 in order to evaluate the vaccine introduction process. Methods: Data collection methods consisted of document review, structured interviews and direct observation. This study collected information from six health region officials, 12 health districts and 36 healthcare institutions. Seventy-two mothers or child carers were also interviewed. Collected data were processed and analysed by Excel, Epi Info and SPSS. Results: A vaccine introduction plan was developed, but was not communicated at the operational level. The planned training for district health care providers was conducted eighteen months after introduction of the vaccine. None of the vaccinating centres had communication support about the new vaccine. Temperature recording was regularly performed in 92% of district deposits and 68% of vaccinating centres. Deteriorated vaccines were observed in 6% of vaccinating centres. Only 3.5% of parents had been informed about introduction of the vaccine. Increased immunization coverage for the third dose of pentavalent vaccine was observed in one half of health districts. Conclusion: Evaluation of the introduction of Haemophilus influenzae type b vaccine highlightsthe strengths and weaknesses of the health system and provides lessons for the introduction of other vaccines into the expanded programme on immunization.
