According to the United Nations International Children's Emergency Fund (UNICEF), 14.5 million children received no routine vaccinations at all in 2023.
These children, known as zero-dose, are at the highest risk of serious illness and death from diseases that vaccines are designed to prevent.
Vaccines are safe, effective, and lifesaving.
The World Health Organisation (WHO) estimates that between 3.5 and 5 million lives are saved globally each year through routine immunisation.
