WHO updates fact sheet on immunization coverage (15 July 2016)

The World Health Organization (WHO) has updated its fact sheet on immunization coverage.

Key Messages:

Immunization averts an estimated 2 to 3 million deaths every year from diphtheria, tetanus, pertussis (whooping cough), and measles.

An additional 1.5 million deaths could be avoided if global vaccination coverage improves.

Global vaccination coverage – the proportion of the world’s children who receive recommended vaccines – has remained steady for the past few years.

In 2015, an estimated 19.4 million infants worldwide were not reached with routine immunization services such as DTP3 vaccine. More than 60% of these children live in 10 countries: Angola, the Democratic Republic of the Congo, Ethiopia, India, Indonesia, Iraq, Nigeria, Pakistan, the Philippines, and Ukraine.
