Building next generation immunization supply chains

Today, thanks to the development of new vaccines, we can protect more children against deadly and debilitating diseases. But the fact that vaccines exist does not mean they reach every child who needs them. One reason: inadequate immunization supply chains to deliver them.

Supply chain challenges are complex, but solvable. For the first time, “Building Next Generation Immunization Supply Chains,” a special edition of the journal Vaccine, compiles the latest evidence on opportunities and challenges facing these systems. This evidence will allow governments and their partners to connect the dots between knowledge and action to invest in reliable, efficient, supply chains that deliver vaccines to all.

Over 500 measles cases were reported for January 2017 in the WHO European Region. Measles continues to spread within and among European countries, with the potential to cause large outbreaks wherever immunization coverage has dropped below the necessary threshold of 95%.

Measles is a highly contagious virus that can cause potentially serious illness. As measles remains endemic in most parts of the world, it can spread to any country, including those that have eliminated the disease.

Immunizing 116 million children against polio in Africa

As part of one of the largest polio vaccination campaigns in Africa, 190 000 vaccinators in 13 countries will immunize 116 million children to tackle the last remaining stronghold of the disease on the continent.

To stop the potentially dangerous spread of the disease as soon as possible, volunteers will deliver polio vaccine to every house across all cities, towns and villages in these countries.
