UNICEF procured 2.5 billion doses of vaccines to children in nearly 100 countries in 2016, reaching almost half of the world’s children under the age of five. The figures, released during World Immunization Week, make UNICEF the largest buyer of vaccines for children in the world.
Nigeria, Pakistan and Afghanistan, the three remaining polio-endemic countries, each received more doses of vaccines than any other country, with almost 450 million doses of vaccines procured to children in Nigeria, 395 million in Pakistan and over 150 million in Afghanistan. UNICEF is the lead procurement agency for the Global Polio Eradication Initiative.
Access to immunization has led to a dramatic decrease in deaths of children under five from vaccine-preventable diseases, and has brought the world closer to eradicating polio. Between 2000 and 2015, under five deaths due to measles declined by 85 per cent and those due to neonatal tetanus by 83 per cent. A proportion of the 47 per cent reduction in pneumonia deaths and 57 per cent reduction in diarrhea deaths in this time is also attributed to vaccines.
Yet an estimated 19.4 million children around the world still miss out on full vaccinations every year. Around two thirds of all unvaccinated children live in conflict-affected countries. Weak health systems, poverty and social inequities also mean that 1 in 5 children under five is still not reached with life-saving vaccines.
“All children, no matter where they live or what their circumstances are, have the right to survive and thrive, safe from deadly diseases,” Dr. Robin Nandy, Chief of Immunization at UNICEF, said.
“Since 1990, immunization has been a major reason for the substantial drop in child mortality, but despite this progress, 1.5 million children still die from vaccine preventable diseases every year.”
Inequalities persist between rich and poor children. In countries where 80 per cent of the world’s under-five child deaths occur, over half of the poorest children are not fully vaccinated. Globally, the poorest children are nearly twice as likely to die before the age of five as the richest.
“In addition to children living in rural communities where access to services is limited, more and more children living in overcrowded cities and slum dwellings are also missing out on vital vaccinations,” Nandy said.
“Overcrowding, poverty, poor hygiene and sanitation as well as inadequate nutrition and health care increase the risk of diseases such as pneumonia, diarrhea and measles in these communities; diseases that are easily preventable with vaccines.”
By 2030, an estimated 1 in 4 people will live in urban poor communities, mainly in Africa and Asia, meaning the focus and investment of immunization services must be tailored to the specific needs of these communities and children, UNICEF said.
