In Nigeria and around the world, citizens, governments, doctors, and parents are fighting polio – and they’re winning. After nearly 30 years of polio eradication efforts, the end is in sight. In 1988, the year the World Health Assembly (WHA) resolved to eradicate polio, there were an estimated 350,000 polio cases globally; last year there were only 359, and this year cases so far are down by 75%.Misbau Lawan Didi leads a club he wants to eliminate. As president of the Polio Survivors Association, he is committed to not only end polio in Nigeria but to eradicate it from the planet. “We are determined,” he says, “to ensure that our members are no more.”
Polio has eluded us for decades. There have been plenty of starts and stops and lots of excitement about the polio eradication effort.
So what makes this time different?
Communities around the world are mobilizing, and momentum is building. Last month, one of the remaining three endemic countries, Nigeria, passed the one year mark without a single case of wild poliovirus. Once the final samples are tested and cleared, the World Health Organization should even be able to declare Nigeria a non-endemic country. Many thought it wouldn’t be done.
Now, Pakistan is embarking on one important step in its fight against polio and implementing the endgame strategy with introduction of the inactivated polio vaccine (IPV) across the country. It will take determination and sustained effort to ensure that it can be done – and with a decentralized health system, years of war, and continued threats against health workers, it will be no easy feat.
Step by step, progress is being made. We are on the brink of an unprecedented accomplishment. Yet, public health experts warn “the last mile” will be the hardest. Ending transmission of the virus in every country will take a focused effort and the use of every available tool against the disease. The Polio Eradication and Endgame Strategic Plan was developed to provide countries with a roadmap to help navigate this challenge. The plan calls on countries to make three important changes to their immunization efforts: 1) to introduce one dose of (IPV) into routine immunization schedules, 2) to strengthen routine immunization, and 3) to eventually withdraw oral polio vaccine (OPV).
The first phase of this plan, the introduction of IPV, is well underway. While there was initial concern over an accelerated timeline, communities and governments around the world have risen to the challenge. The introduction of IPV will be one of the fastest rollouts in history. Out of 126 oral polio vaccine (OPV) only using countries, 30 have now introduced. Today, on August 20th, Pakistan launches its nationwide rollout, which is no small feat. The significance of this rollout is monumental.

Introducing a new vaccine involves hundreds of technical and logistic details. There are budget considerations, procurement, storage and transport of vaccines, training of health workers, and communication with parents. Countries need to assess their systems and strengthen necessary components. In Nigeria, for example, communicating with the public was particularly important as skepticism about the polio vaccine halted past efforts. When Nigeria introduced the new polio vaccine in February of this year, community and religious leaders were active in the outreach to parents. In markets and in mosques, the public was told about the importance of immunization and using the IPV vaccine in the battle against polio. In February, when Nigeria became the first polio endemic country to introduce the vaccine, it was widely accepted by parents.
We are down to the last three polio endemic countries – Nigeria, Pakistan and Afghanistan – and now there is even greater hope. Last year, there were no new members of Nigeria’s Polio Survivors Association as the country did not have any cases of the disease. Work in Nigeria is far from over, but the effort is paying off: two more years without a reported case and Nigeria can be certified as polio free.
The same can be true in Pakistan and the other countries where communities are hard at work to protect their children and eradicate this virus. This time it really can be different. Pakistan, is your time now?

Inactivated Polio Vaccine and Its Role in Eradication Plan
By Lois Privor-Dumm
It’s been just under a decade since the focus of my work shifted to resource-constrained countries. At the time, it seemed a far-off dream that so much progress could be made in protecting children from vaccine-preventable diseases. Eradication efforts had only ever succeeded against one disease – smallpox – and there were still many cases of polio in endemic countries (which at the time were Afghanistan, India, Nigeria, and Pakistan). Immunization was discussed, but never received the focus it does today. Now, on this World Polio Day, I reflect on where the world was and where it is today - closer than ever to reaching a goal of ending polio for good – AND doing it while strengthening immunization programs that have been all too weak in the past.
The rollout of IPV in the Philippines was marked by a ceremony attended by several health dignitaries including the Secretary of Health, Enrique Ona, the Undersecretary of Health, Jeanette Garin and the Assistant Secretary of Health Enrique Tayag among other high-ranking officials.
In 1988, when the Global Polio Eradication Initiative (GPEI) began, polio paralyzed more than 1,000 children worldwide every day. Today thanks to millions of volunteers more than 2.5 billion children have been immunized against polio. Global immunization campaigns have reduced polio by 99% worldwide. Eradication is within reach.
This year kicked off with a huge milestone, with India being declared polio-free in January, leaving just three countries with ongoing transmission. While Pakistan faces many challenges and has seen an increase in polio cases this year, Nigeria has had the fewest cases of wild poliovirus ever, with just six cases so far this year, and Afghanistan’s burden also remains low with just 12 cases this year.
Another important step forward was taken this year as countries began introducing inactivated poliovirus vaccine (IPV), an important milestone in the Polio Eradication and Endgame Strategic Plan, an ambitious but achievable plan endorsed by the World Health Assembly in 2013. The plan calls on countries to introduce at least one dose of IPV into routine immunization schedules and gradually withdraw all oral polio vaccines (OPV). Until now, OPV has been the primary tool in the global polio eradication effort, and has been instrumental to achieving the reach necessary to eliminate polio from all but three countries, and to reduce cases to a mere fraction of historic trends in Nigeria, Pakistan, and Afghanistan. However, new evidence now clearly demonstrates that adding one dose of IPV to multiple doses of OPV is the most effective method available to stop the virus and protect children.
The amazing part is that countries are introducing IPV along with other important new vaccines. In September, Nepal became the first country to introduce IPV with Gavi support. Gavi-supported rollouts will continue, as more than 90% of Gavi-eligible countries have applied for support. Next month, Nepal is also expected to introduce pneumococcal conjugate vaccine. Gone are the days when countries have to wait years between vaccine introductions. In fact, in 2014, five countries have introduced more than one vaccine already, and nearly 15 more multiple introductions are planned for next year, accelerating the path to reducing both child death and severe illness.
But it’s not only Gavi supported countries that are making strides. Middle-income countries, where most of the world’s poor reside, are also recognizing the importance of IPV and making the investment to introduce this and other new vaccines. Earlier this month, the Philippines became one of the first non-GAVI countries to start the transition from an all-OPV schedule to add one dose of IPV. The global rollout of IPV will continue across 126 countries through the end of 2015.
IVAC is proud to be part of the global efforts to help eradicate polio and support the introduction of new vaccines through targeted advocacy efforts in middle-income countries, helping to engage and sensitize civil society, and supporting communications activities of partners. It is a big job ahead, but with committed governments, partners and advocates, we now know it is possible. The hard part of our job as advocates is just beginning, but we look forward to more milestones in the fight against polio in the coming year, as the finish line gets closer.

Today is a landmark day, one that many global health experts thought might not happen. Today marks three years since the last case of wild polio in India, the requirement to officially certify the country, and with it the WHO South-East Asia Region, polio-free. While the official declaration is not due until March when a WHO Regional Certification Committee reviews all the data, today is a day to celebrate and to be remembered in India and around the world for years to come.

It is a day to congratulate India, but also the global community. It is a day that gives us all strengthened hope and confidence in achieving the goal of global polio eradication. In 1998, India had a high of nearly 2,000 cases of paralytic polio from the wild poliovirus, and as recently as 2009, it still was home to most of the world’s polio cases. By 2011, it had wiped out wild polio cases, and now it has maintained that status for three years. India’s large, dense, and often migratory population combined with poor sanitation conditions in parts of the country created some of the most difficult conditions throughout the world to control disease. However, with a depth of commitment from all levels of government and civil society and dedication of significant resources, India achieved this mammoth goal. It could not have been done without the work of millions of individuals, including the 2.3 million vaccinators, the thousands of clinicians and epidemiologists in more than 33,000 surveillance sites, the religious leaders and advocates committed to on-the-ground outreach, and the leaders across government and industry who together contributed nearly US$2 billion in funding.
Thanks to all of these individuals, India is now polio-free, and its triumph over polio is a massive public health achievement---one that will leave a lasting impact on children's health in India and around the world. It is also a testament to the power of immunizations, which have been saving lives in India and around the world for centuries.
India has achieved a laudable reduction in global child deaths in recent years, and vaccines have been one of the most effective interventions in this effort. Not only have vaccines prevented deaths, but they’ve also helped children stay healthy and averted crippling social and economic costs to families and society. Beyond polio, India’s other great achievements related to vaccines are highlighted in this infographic.
Vaccines clearly work and they clearly work in India. As coverage levels increase and new vaccines are introduced into its Universal Immunization Programme, disease reduction will amplify, and children will lead healthier, longer lives. These inspiring efforts should be applauded along with India’s polio achievement.
India’s achievements should also inspire the global community to rededicate our efforts to ensure every child around the world is protected from preventable diseases. We have a unique window of opportunity to change history by eliminating polio from the three remaining countries where transmission has not yet been stopped – Pakistan, Afghanistan, and Nigeria – and maintaining disease control in other countries where elimination is fragile and polio threatens to return. With much learned from India’s success, communities, countries and the global community have a strong, actionable plan to achieve a polio-free world by 2018.
Ending polio everywhere, forever, is a critical step toward improving the lives of the world’s most vulnerable children. As India has clearly shown, polio eradication can lead the way for other child health initiatives, by strengthening surveillance systems, building networks of trained community health workers, and engaging leaders from across diverse disciplines. The job is not yet done; India and other countries around the world will need to sustain and continue to build on the progress to date while planning for the next step of introducing at least one dose of inactivated polio vaccine.
The remaining polio-endemic countries should have a deep sense of hope, bolstered by the accomplishments and lessons learned in India, that this goal is at their fingertips. The scientific, public health, communication, and organizational tools are in place. With the right political will, polio will be wiped out; there will remain substantial and at times unanticipated challenges to match the accomplishment of India in the remaining countries, but these are surmountable. There is a lot to be optimistic about. India has demonstrated to the world what is possible when the community in all its dimensions – local and global, political and religious, scientific and lay – has a common commitment. We call on all partners to continue without wavering the march toward worldwide polio eradication and in so doing achieve the purest measure of health equity.
