Nine polio areas of expertise were applied to broader immunization and mother, newborn and child health goals in ten focus countries of the Polio Eradication Endgame Strategic Plan: policy & strategy development, planning, management and oversight (accountability framework), implementation & service delivery, monitoring, communications & community engagement, disease surveillance & data analysis, technical quality & capacity building, and partnerships. Although coverage improvements depend on multiple factors and increased coverage cannot be attributed to the use of polio assets alone, 6 out of the 10 focus countries improved coverage in three doses of diphtheria tetanus pertussis containing vaccine between 2013 and 2015. Government leadership, evidence-based programming, country-driven comprehensive operational annual plans, community partnership and strong accountability systems are critical for all programs and polio eradication has illustrated these can be leveraged to increase immunization coverage and equity and enhance global health security in the focus countries.

Background: To monitor immunization-system strengthening in the Polio Eradication Endgame Strategic Plan 2013-2018 (PEESP), the Global Polio Eradication Initiative identified 1 indicator: 10% annual improvement in third dose of diphtheria- tetanus-pertussis-containing vaccine (DTP3) coverage in polio high-risk districts of 10 polio focus countries.

Methods: A multiagency team, including staff from the African Region, developed a comprehensive list of outcome and process indicators measuring various aspects of the performance of an immunization system.

Results: The development and implementation of the dashboard to assess immunization system performance allowed national program managers to monitor the key immunization indicators and stratify by high-risk and non-high-risk districts.

Background: The Polio Eradication and Endgame Strategic Plan (PEESP) established a target that at least 50% of the time of personnel receiving funding from the Global Polio Eradication Initiative (GPEI) for polio eradication activities (hereafter, "GPEI-funded personnel") should be dedicated to the strengthening of immunization systems. This article describes the self-reported profile of how GPEI-funded personnel allocate their time toward immunization goals and activities beyond those associated with polio, the training they have received to conduct tasks to strengthen routine immunization systems, and the type of tasks they have conducted.

Methods: A survey of approximately 1000 field managers of frontline GPEI-funded personnel was conducted by Boston Consulting Group in the 10 focus countries of the PEESP during 2 phases, in 2013 and 2014, to determine time allocation among frontline staff.

Unlabelled: Vaccination rates have improved in many countries, yet immunization inequities persist within countries and the poorest communities often bear the largest burden of vaccine preventable disease. Madagascar has one of the world's largest equity gaps in immunization rates. Barriers to immunization include immunization supply chain, human resources, and service delivery to reflect the health system building blocks, which affect poor rural communities more than affluent communities.

Responding to regional advancements in combating measles, the World Health Organization in May 2008 called for an assessment of the feasibility of measles eradication, including whether sufficient vaccine supply exists. Interviews with international health officials and vaccine-makers provided data for a detailed model of worldwide demand and supply for measles-containing vaccine (MCV). The study projected global MCV demand through 2025 with and without a global eradication goal.

Background: In 2000, reuse of disposable syringes and inadequately sterilized syringes resulted in 39% of all injections being unsafe, causing 22 million infections. We describe the contribution of measles supplemental immunization activities (SIAs) and Global Alliance for Vaccines and Immunisation (GAVI) funding in replacing disposable and sterilizable syringes with auto-disable (AD) syringes to improve injection safety in 39 African countries.

Methods: We assessed trends in nationwide introduction of AD syringes against measles catch-up SIAs and GAVI funding using World Health Organization/United Nations Children's Fund (UNICEF) Joint Reporting Form for Immunization and UNICEF supply data.

Background: The Millennium Development Goal 4 (MDG4) to reduce mortality in children aged <5 years by two-thirds from 1990 to 2015 has made substantial progress. We describe the contribution of measles mortality reduction efforts, including those spearheaded by the Measles Initiative (launched in 2001, the Measles Initiative is an international partnership committed to reducing measles deaths worldwide and is led by the American Red Cross, the Centers for Disease Control and Prevention, UNICEF, the United Nations Foundation, and the World Health Organization).

Methods: We used published data to assess the effect of measles mortality reduction on overall and disease-specific global mortality rates among children aged <5 years by reviewing the results from studies with the best estimates on causes of deaths in children aged 0-59 months.

Two doses of measles vaccine to children reduce measles related deaths. The first dose is delivered through the routine immunization system to infants and the 2nd dose through campaigns or routine immunization system, whichever strategy reaches the highest coverage in the country. Experience in 46 out of 47 measles priority countries has shown that measles vaccination using mass vaccination campaigns can reduce measles related deaths, even in countries where routine immunization system fails to reach an important proportion of children.
