Sanofi pasteur inked a deal related to development and marketing of Acambis’ ChimeriVax™-West Nile vaccine. Acambis stands to earn over $80 million in this exclusive global collaboration.


ChimeriVax-West Nile is in a Phase II safety, tolerability, and immunogenicity trial in the U.S. in adults over 41 years. Acambis will continue development and will also be responsible for the filing of a license application in the U.S.


Sanofi pasteur will initially pay $10 million.

Acambis will also get royalties on global net sales.
