The Trump administration is planning to end funding for Gavi, a global health organization that helps provide vaccines and other life-saving care to developing countries, The Guardian reported.

A 281-page spreadsheet obtained by the New York Times lists the Trump administration’s plans for thousands of foreign aid programs, including financial cuts to the organization that buys vaccines for children, as well as scaling back on programs that combat malaria in developing countries.

Gavi is estimated to have saved the lives of 19 million children since it was set up 25 years ago with the US contributing 13% of its budget, the Times said.

“The US has historically been one of Gavi’s biggest donors and I hope that longstanding champions on Capitol Hill will urge the administration to reverse course,” said Janeen Madan Keller, policy fellow and deputy director of the global health policy program at the Center for Global Development, according to The Guardian.

She added: “Gavi is one of the most impactful global health initiatives. We know that vaccinating children is one of the most cost-effective ways to improve health and save lives – which is exactly why Gavi has enjoyed bipartisan support to date.

“This latest move will turn back years of hard-won progress and stymie Gavi’s efforts to stop the spread of infectious disease outbreaks before they reach the US border.”
