Global vaccine access
1 in 5 children lack access to lifesaving vaccines.
Lack of access to vaccines leaves children at risk of death, disability, and illness from preventable diseases.
In 2023, over 14.5 million children under the age of 1 did not receive basic vaccines (referred to as "zero-dose" children). This is nearly 2.7 million more than in 2019 before the start of the pandemic.
Almost all zero-dose children live in low- and middle-income countries, primarily in Africa and South-East Asia. Over half of these children live in just 10 countries:
- Angola
- Afghanistan
- Democratic Republic of the Congo
- Ethiopia
- India
- Indonesia
- Nigeria
- Pakistan
- Sudan
- Yemen
