Excerpt: In the chart below we see the global number of deaths of children younger than 5 years per year from 1990 to 2015. The number of deaths which are wholly or partially preventable by vaccines are shown in color.3 The chart shows that the reductions in child deaths over this 25-year period were primarily achieved by a reduction of the number of deaths from vaccine-preventable diseases: The decline in causes which are not vaccine preventable has been modest, while the number of child deaths caused by diseases for which vaccines are available declined from 5.1 million deaths in 1990 to 1.5 million deaths 25 years later.
