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 immunisation 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 percent and those due to neonatal tetanus by 83 percent.
A proportion of the 47 percent reduction in pneumonia deaths and 57 percent reduction in diarrhoea 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,” said Dr. Robin Nandy, Chief of Immunisation at UNICEF.
“Since 1990, immunisation 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 percent 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,” said Nandy.
“Overcrowding, poverty, poor hygiene and sanitation as well as inadequate nutrition and health care increase the risk of diseases such as pneumonia, diarrhoea 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 immunisation services must be tailored to the specific needs of these communities and children, UNICEF said.
