World Health Organisation (WHO) has confirmed that Africa is facing serious immunisation challenges, with one in five children still under-vaccinated, while vaccine-derived poliovirus continues to pose a threat to the region.

According to the global agency, about 6.7 million children in Africa have not received any vaccine at all in 2023, hence the need for renewed collective commitment to achieve equitable access to life-saving vaccines for every child.

The Acting WHO Regional Director for Africa, Dr. Chikwe Ihekweazu, who disclosed this in a message to mark the 2025 African Vaccination Week, stated that WHO and partners were working closely with countries to identify and reach zero-dose children, integrate immunisation into primary health care, and build stronger, more resilient health systems.

He observed that initiatives like the Big Catch-Up were helping to restore essential services, while the introduction of new vaccines, such as those for malaria and human papillomavirus (HPV), was expanding the disease prevention arsenal.

Ihekweazu observed that immunisation is not only one of the most effective public health tools, but also a fundamental right, a shared responsibility, and a vital investment in “our future.”

“The WHO Regional Office for Africa remains steadfast in its support to countries and partners, working together to ensure that immunisation for all is not just a goal, but a reality,” he added.
