Burkina Titao vaccination (1)

The Zero-dose Immunisation Programme (ZIP) was Gavi’s first designated multi-country funding for humanitarian partners to immunise children in missed communities impacted by conflict and crisis. Contributing to Gavi’s 2021–2025 strategy (Gavi 5.0/5.1)’s vision of “Leaving no one behind with immunisation,” ZIP grantees deliver all scheduled vaccine doses to children from birth to age five in communities where conflict impedes government health services. ZIP learning informs the fragile & humanitarian approach of the Gavi 6.0 strategy.

ZIP, Gavi’s Humanitarian Partnerships Programme

In some parts of the world, vaccinating a child isn’t routine; it’s a race against time, distance, and instability.

Gavi’s ZIP humanitarian partners go the extra mile to reach communities affected by conflict, crisis, and displacement, communities where children have never been vaccinated.

“Don’t ask for anything else. Just ask for safe passage”: negotiating access for vaccines amid conflict

August 18, 2026

Routine vaccination services had been unavailable to children born during the long-running conflict between the Tigray and Amhara regions of Ethiopia. In 2022, REACH was able to start negotiations with a wide range of officials in the area to gain the access they needed.

Gavi’s Humanitarian Partnerships: achievements and learning, 2022–2024

In partnership with the International Rescue Committee (IRC) and others, the Gavi-funded Humanitarian Partnerships (ZIP) is breaking new ground in how immunisation services reach communities affected by insecurity, conflict or crisis. 

The programme, which was launched in 2022, spans across 11 African countries in the Sahel and Horn of Africa. This report showcases the achievements and learning from the first two ZIP awards Raise 4 Sahel and REACH.

From December 2022 through June 2024, ZIP, Gavi’s Humanitarian Partnerships, provided 845,000 first doses and 479,000 last doses of vaccines to infants and children in communities where national immunisation programmes (NIPs) face barriers associated with insecurity, conflict or crisis across 11 African countries.

Gavi, the Vaccine Alliance, recognises the leadership of NIPs as primary recipients of Alliance support. Gavi also recognises that external shocks can create exceptional and often time-bound barriers that restrict NIP access to communities. When these cannot be overcome with Gavi cash grants to governments, gaps in vaccine programming leave communities vulnerable. Gavi upholds an equity imperative to ensure no child is left behind with immunisation, including children in communities beyond the reach of government health services due to insecurity, conflict or crisis.
