2016 WHO Immunization Progress Report
Stamen worked with the World Health Organization’s Department of Immunization to visualize the progress of global immunization. After more than 30 years of publishing their annual immunization report, WHO called on Stamen to bring a new and improved visual approach to their storytelling. These are the highlights from the report.
DTP3 Coverage and Numbers of Unvaccinated Children by Country
Significant progress has been achieved over the last 15 years
A look at the map shows that a lot of the progress has been made in countries such as India, Ethiopia, and the Democratic Republic of the Congo since 2000. However, at the same time conflict in Syria, Iraq, and Ukraine led to the collapse of previously well performing systems there.
Many countries still struggle to achieve high immunization coverage. 67 countries have not yet been able to reach and sustain the Global Vaccine Action Plan coverage targets of 90%, and will need to carefully examine their data and develop strategies to address gaps in immunization coverage. Despite recent progress, the challenges remain largest in the African, Eastern Mediterranean and South East Asian regions. the African region still has most unvaccinated children, as well as most of the countries with very low coverage.
Estimates for the Countries with the Largest Cohort of Unvaccinated Children.
Most progress has been made in India, Ethiopia, and the Democratic Republic of Congo, while coverage in Pakistan and Indonesia is stagnating. Iraq and Ukraine enter the list as immunization systems have suffered because of conflict. The Philippines experienced stock outs in 2015, and Angola has seen a deteriorating performance over the last few years
The most significant year-over-year changes in 2015 include a drop in coverage in the Philippines, due to vaccine stock-outs, and a further deterioration in South Sudan. On the other hand, Chad, Nigeria, and Ethiopia all report robust progress. Upcoming coverage evaluation surveys will need to confirm that progress.
While many countries, such as India, Lao, Chad, and Democratic Republic of Congo (DRC) show sustained progress over the longer term, other countries are yet to show improvement in their performance (Indonesia, Pakistan). Other countries have not been able to sustain high coverage levels (Guatemala and Congo), or have seen positive trends reverted recently (Angola and Mauritania).
Immunization in countries with ongoing conflict.
The impact of conflict on immunization performance is unambiguous and devastating
Immunization in countries afflicted by Ebola.
The Ebola outbreak in West Africa 2014 and 2015 had a different impact in each of the affected countries. Sierra Leone experienced a relatively mild impact on programme performance (-9 percentage points in 2014) and already seems to be recovering well, while the hit on performance in Liberia (-26 percentage points in 2014) was much harder. Coverage in Guinea was already struggling before Ebola hit (-12 percentage points in 2014).
