The Long and Winding Road: In the world’s far corners getting vaccines
The itinerary is ambitious: It begins with a flight from POLIO MANUFACTURER LOCATIONTK to Islamabad, followed by a road trip by jeep for hundreds more miles. Then when the road runs out, it’s on foot from there. A donkey carries the cargo over the rocky hills, with packs securely fastened to keep them from slipping off. The trail continues for mile upon desolate mile, until a small village appears on the horizon, the tiniest of dots on the map.
This is not the travel plan of an overly adventurous trekker. It is the path a UNICEF polio vaccine must take to reach children in just one remote community in Pakistan, one of the last countries on earth where the crippling childhood disease remains endemic.
Getting any vaccine to the world’s most vulnerable children takes both technical and logistical ingenuity. To stay effective, vaccines for polio, measles, rubella and tetanus must be kept consistently cold — at or close to freezing — from the point of manufacture right until they are administered. This can be especially difficult when a vaccine is crossing time zones, moving over rugged land or traversing areas embroiled in conflict. The longer it travels the greater the risk; all it takes is one crack in an insulated storage container to render a vaccine useless.
Keeping a vaccine’s temperature constant — or maintaining the “cold chain,” as it’s called — is but one challenge of global immunization efforts. In Nigeria, for example, where UNICEF and Rotary International have been partnering since 1988 to end polio, violence has both interfered with the delivery of vaccines and endangered the lives of those who administer them. Misinformation and rumors about vaccine safety can also get in the way. Reaching nomadic populations, educating parents and galvanizing community support are other hurdles. All of which makes the recent good news out of Nigeria — one full year with no new cases of wild poliovirus — all the more impressive.
But it starts to make sense when you consider the dedication and resourcefulness of the individuals working at every twist and turn of a vaccine’s journey: The Nigerian government, thousands of health workers, countless community and religious leaders and international coalitions like the Global Polio Eradication Initiative, which UNICEF and Rotary International helped spearhead in 1988 all played vital roles to make a polio-free Nigeria even possible.
Vast public health initiatives can make a lifesaving difference — and build a global network of people united to give every child, everywhere, a chance at a better life. Here, a look at who they are and how they operate.
By air, by sea, by reindeer
Getting vaccines to the children who need them can be logistically challenging, even physically grueling. On its path from manufacture to child, vaccines travel by airplane, boat, truck, motorbike, even reindeer. To retain its life-saving benefits, the precious cargo must be kept cold every step of the way.
When disaster strikes
In times of crisis, UNICEF routinely administers vaccines as part of emergency relief efforts at refugee camps and in communities that need humanitarian support after cyclones, earthquakes or floods. Though tragic, a humanitarian emergency can sometimes present an opportunity to immunize children who might not otherwise have been reached.
When violence forces families in places like Syria and South Sudan to flee, UNICEF and its partners must work even harder to prevent lapses and immunization gaps that can increase risks for an entire region. A recent study in The Lancet found that gaining parent and caretaker support for vaccination programs, particularly in regions beset by conflict, poses other obstacles. Polio’s recent resurgence in Syria — where four years of crisis is being blamed for 2014’s first polio outbreak there since 1999 — shows how such chaos threatens children’s lives and why swift and thoughtful action is so important.

The Finish Line
Once child and vaccine finally meet, inoculation can be as easy as squeezing the end of a dropper. But the work doesn’t stop there. Keeping track of who is reached and educating parents and caregivers about what’s next is crucial. Some immunization campaigns chart their progress by providing vaccinated children with certificates or marking their fingers with ink to show that they are now protected. Fostering awareness of how immunizations work — how many doses it takes to immunize depends on the child’s health and nutritional status — is key to protecting the lives of all children.
