The French Government already has an existing agreement with Sanofi Pasteur that allows the French Ministry of Health to purchase vaccines for viruses identified by the World Health Organisation.
The vaccine will be manufactured in Val de Reuil, France.
According to Sanofi Pasteur final dosage requirements are yet to be determined and will be based on clinical trials outcomes.
Final formulation, filling and distribution of the vaccine will also be determined in coming months.
Sanofi Pasteur estimates that the first A(H1N1) vaccine doses will be ready for public health officials within four to six months.
