This immunization brief, written in French for a DRC audience in Tanganika province, discusses the ambitious "Mashako Plan" to increase routine immunization coverage in DRC by 15 percent in 18 months. The brief recommends that the provincial government emphasize routine immunization, deliver on the commitments of a recent memorandum of understanding with the Bill & Melinda Gates Foundation, and disburse immunization funding in order to bring the promise of immunization to all families in Tanganika.
