Despite substantial progress, global polio eradication has remained elusive. Indigenous wild poliovirus (WPV) transmission in 4 endemic countries (Afghanistan, India, Nigeria, and Pakistan) persisted into 2010 and outbreaks from imported WPV continued. By 2013, most outbreaks in the interim were promptly controlled. ⋯ India is now polio-free. The challenges to success in the remaining polio-endemic countries include (1) threats to the security of vaccinators in each country and a ban on polio vaccination in areas of Afghanistan and Pakistan; (2) a risk of decreased government commitment; and (3) remaining surveillance gaps. Coordinated efforts under the International Health Regulations and efforts to mitigate the challenges provide a clear opportunity to soon secure global eradication.

The world is on the verge of achieving global polio eradication. During >25 years of operations, the Global Polio Eradication Initiative (GPEI) has mobilized and trained millions of volunteers, social mobilizers, and health workers; accessed households untouched by other health initiatives; mapped and brought health interventions to chronically neglected and underserved communities; and established a standardized, real-time global surveillance and response capacity. It is important to document the lessons learned from polio eradication, especially because it is one of the largest ever global health initiatives. ⋯ We have summarized what we believe are 10 leading lessons learned from the polio eradication initiative. We have the opportunity and obligation to build a better future by applying the lessons learned from GPEI and its infrastructure and unique functions to other global health priorities and initiatives. In so doing, we can extend the global public good gained by ending for all time one of the world's most devastating diseases by also ensuring that these investments provide public health dividends and benefits for years to come.

Since the launch of the Global Polio Eradication Initiative (GPEI) in 1988, the number of polio endemic countries has declined from 125 to 3 in 2013. Despite this remarkable achievement, ongoing circulation of wild poliovirus in polio-endemic countries and the increase in the number of circulating vaccine-derived poliovirus cases, especially those caused by type 2, is a cause for concern. ⋯ This objective has inspired renewed consideration of how the GPEI and RI programs can mutually benefit one another, how the infrastructure from the GPEI can be used to strengthen RI, and how a strengthened RI can facilitate polio eradication. The PEESP is the first GPEI strategic plan that places strong and clear emphasis on the necessity of improving RI to achieve and sustain global polio eradication.

Review
Oversight role of the Independent Monitoring Board of the Global Polio Eradication Initiative.
The Global Polio Eradication Initiative (GPEI) established its Independent Monitoring Board (IMB) in 2010 to monitor and guide its progress toward stopping polio transmission globally. The concept of an IMB is innovative, with no clear analogue in the history of the GPEI or in any other global health program. The IMB meets with senior program officials every 3-6 months. ⋯ Its areas of focus have included escalating the level of priority afforded to polio eradication (particularly by recommending a World Health Assembly resolution to declare polio eradication a programmatic emergency, which was enacted in May 2012), placing greater emphasis on people factors in the delivery of the program, encouraging innovation, strengthening focus on the small number of so-called sanctuaries where polio persists, and continuous quality improvement to reach every missed child with vaccination. The IMB's true independence from the agencies and countries delivering the program has enabled it to raise difficult issues that others cannot. Other global health programs might benefit from establishing similar independent monitoring mechanisms.

Before vaccination, pertussis was a universal disease of early childhood. Although apparent control of the disease in the United States and other countries was achieved through vaccination, pertussis is resurgent. Though acellular vaccines have been in use for 20 years, new data are emerging on their effectiveness and durability of protection and the contribution of these characteristics to the resurgence of pertussis.
