Mass vaccination campaign to protect millions against yellow fever

One of the largest emergency vaccination campaigns ever attempted in Africa has begun in Angola and the Democratic Republic of Congo as WHO and partners work to curb a yellow fever outbreak that has killed more than 400 people and sickened thousands more. Working with Ministries of Health in the 2 countries, WHO is coordinating 56 global partners to vaccinate more than 14 million people against yellow fever in more than 8000 locations.

Publication of WHO’s first dengue vaccine position paper

In a new position paper published in today’s edition of the Weekly Epidemiological Record, WHO recommends that countries should consider introduction of the dengue vaccine CYD-TDV or Dengvaxia® only in geographic settings where epidemiological data indicate a high burden of disease.

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.
