Today, world leaders reaffirmed their commitment to protecting children from vaccine-preventable diseases, raising $9 billion for @gavi. This reflects strong global confidence in vaccines as one of the most effective investments in global health. As a founding partner, the @gatesfoundation committed $1.6 billion to support continuing Gavi’s proven impact: 1.1 billion children vaccinated and nearly 19 million deaths averted over the past 25 years. But Gavi still faces a funding gap—driven in part by the U.S. administration’s intention to withdraw support. If Congress allows this to happen, the consequences will be devastating. Hundreds of thousands, if not millions, of preventable deaths will occur, especially among mothers and children. Science welcomes scrutiny, but it demands evidence, too. And the science is clear: vaccines save lives. Without continued U.S. support for Gavi, far too many lives will be lost.
