A world in which our children and their children grow up free from the threat of polio and other preventable diseases is a dream that everyone shares. However, unlike most dreams, this one is achievable.
Over my lifetime, I have been fortunate enought to witness the extraordinary impact that vaccines have had on protecting children from illness and death, especially in the developing world.
Vaccines have always had a special meaning for me. As a young child in South Africa, I nearly died from polio. At that time — in the early 1930s — there was no vaccine for this highly infectious disease. With good reason, parents everywhere were terrified that the polio virus would reach their doorstep like a plague, striking their child and causing irreversible paralysis in a matter of hours, or worse, death in a matter of days.
The doctors told my parents that little could be done for me, so my father prepared for my funeral. Fortunately, I made a full recovery, except that I lost the use of my right hand. I have gone on to live a wonderful life, but the paralysis in my hand is a daily reminder of why we must urgently pursue the eradication of polio and ensure that all children have access to the vaccines they need.
Just a quarter-century ago, polio was endemic in 125 countries and paralyzed more than 1,000 children every day. Today, we have the lowest number of cases of polio in fewer countries than ever before.
Last year, India — once thought to be the most difficult place to eradicate polio — was declared polio-free. In the remaining three countries where polio has not yet been eliminated — Pakistan, Afghanistan and Nigeria — there were just 223 reported cases in last year. This makes me optimistic that I will live to celebrate the day when this dreaded disease is stamped out forever.
The remarkable progress that we have made so far is the result of a sustained global effort, supported by significant resources committed by donor and affected countries, millions of dedicated health workers and sustained political will to get the job done. However, we must finish what we have started. Until the polio virus is eradicated everywhere, no country is safe from reinfection.
At the same time, we must make the most of scientific advances over the last half-century, which have made vaccines for other preventable diseases the most powerful and cost-effective healthcare investment that exists. Vaccines are inexpensive, easy to deliver and they protect children for a lifetime. They have already eradicated smallpox and dramatically reduced child deaths and disease associated with measles, diphtheria and tetanus.
Yet, sadly, a child still dies every 20 seconds from diseases like pneumonia, which can be prevented by a vaccine. Most of them live in poor and remote communities that still lack access to the basic vaccines that are universally available in better-off countries. This is one of the reasons why a child born in a high-income country is 18 times less likely than a child born in a low-income country to die before reaching the age of five.
Fortunately, the world is taking action. This week in Abu Dhabi Crown Prince Mohamed bin Zayed bin Sultan Al Nahyan, in partnership with UN Secretary-General Ban Ki-moon and Bill Gates, is hosting the world’s first global summit dedicated to ensuring that all children everywhere have access to the full benefits of vaccines.
