Edelman is replacing Hill & Knowlton on the Global Fund to Fight AIDS, Tuberculosis and Malaria's six-figure PR and media training account.
H&K was the three-year incumbent, but the Global Fund has worked with Brunswick and Publicis in the past, as well.
The Fund released an RFP in October to review the account, worth from $300K-$400K annually, including PR, crisis communications and media training for staffers and executives of the Geneva-based public/private entity.
The Global Fund, created with the support of the Bill & Melinda Gates Foundation, is the largest global backer of projects to prevent infection disease.
