Writing in the ONE blog, Dagfinn Høybråten, chair of the GAVI Alliance Board, reflects on the organization’s 2013 Mid-Term Review, released last week, which found the alliance is on track to “immunize an additional quarter of a billion children by 2015, and prevent four million future deaths in the process.” He states, “While we may not be there yet, it is nevertheless a huge accomplishment and one that is not just measured in lives saved,” adding, “But now with two years to go, there is indeed much left to do if we are to fulfill our promises” (10/18).
