In 2019, an estimated 14 million infants were still not reached by vaccination services

Immunization is one of the most cost-effective public health interventions to date, averting an estimated 2 to 3 million deaths every year. As a direct result of immunization, the world is closer than ever to eradicating polio, with only two remaining polio endemic countries – Afghanistan and Pakistan. Deaths from measles, a major child killer, declined by 73 per cent worldwide between 2000 and 2018 preventing an estimated 23.2 million deaths. And as of today, all but 12 countries have eliminated maternal and neonatal tetanus, a disease with a fatality rate of 70 to 100 per cent among newborns.

The percentage of children receiving the diphtheria, tetanus and pertussis vaccine (DTP) is often used as an indicator of how well countries are providing routine immunization services. In 2019, global coverage rates for the third dose of the diphtheria, tetanus and pertussis vaccine (DTP3) reached 85 per cent, up from 72 per cent in 2000 and 20 per cent in 1980. Still, progress has stalled over the decade, and 85 countries have yet to achieve the Global Vaccine Action Plan (GVAP) target of 90 per cent or greater coverage of DTP3. [1] In 2019, 19.7 million children under 1 year of age worldwide did not receive the three recommended doses of DTP, and the number of zero-dose children – defined as children in the same age group who did not benefit from any vaccination – was an estimated 13.8 million.
