Immunization, Vaccines and Biologicals

Global immunization coverage sustained in past 5 years

New data on global immunization coverage show that 86% of the world’s children received 3 doses of diphtheria-tetanus-pertussis (DTP3) vaccines in 2015, a coverage level that has been sustained above 85% since 2010.

The number of children who did not receive routine vaccinations dropped to an estimated 19.4 million, down from 33.8 million in 2000.

Lower doses of yellow fever vaccine could be used in emergencies

The WHO Strategic Advisory Group of Experts on Immunization (SAGE) found that one fifth of the regular dose of yellow fever vaccine could be used to control an outbreak in case of vaccine shortages. In the current yellow fever outbreak, almost 18 million doses of yellow fever vaccine have been distributed in emergency vaccination campaigns in Angola, Democratic Republic of the Congo, and Uganda.

The 2016 Vaccine Development Pipeline

A special issue of the journal Vaccine, guest-edited by WHO and published today, focuses on the research and development pipeline of vaccines against 25 pathogens for which no licensed vaccines currently exists but for which there is high public health importance, as identified by the WHO Product Development for Vaccines Advisory Committee (PDVAC).

Delegates discuss ways to get progress towards global immunization goals back on track

Twenty five speakers took the floor during the Global Vaccine Action Plan discussion at the World Health Assembly. The global vaccination targets remain off-track with gaps in immunization coverage and slow progress in the elimination of maternal and neonatal tetanus, measles and rubella.

Delegates noted that when countries and partners establish and enforce clear accountability systems, measure results and take corrective actions when results are not achieved, gaps in immunization can be closed.
