Sanofi Pasteur and Butantan Institute to Provide A(H1N1) Vaccine to Brazilian Government

sanofi-aventisSanofi Pasteur, the vaccines division of sanofi-aventis Group (EURONEXT : SAN and NYSE : SNY), has signed an agreement with Butantan Institute for the production and supply of a vaccine against the novel A(H1N1) influenza virus for the Brazilian Government. This contract was announced during a state visit to Brazil by French President Nicolas Sarkozy.

The order from the Brazilian Ministry of Health provides for the initial supply of 18 million doses of the new A(H1N1) influenza virus vaccine: one million doses in final presentation and 17 million doses in bulk form. The agreement includes an option for an additional 15 million doses of A(H1N1) vaccine should the World Health Organization (WHO) request influenza manufacturers to switch production from the regular Southern Hemisphere Seasonal influenza vaccine to the Pandemic A(H1N1) vaccine.

Commenting on the agreement, Wayne Pisano, President and Chief Executive Officer of Sanofi Pasteur said: "Sanofi Pasteur and Butantan Institute are historical and successful partners who will bring a tailored response to public health needs in the context of pandemic influenza in Brazil. Our goal is to produce and deliver as quickly as possible the pandemic vaccine which meets the requirements defined by the Brazilian health authorities. We rely on our close collaboration with Butantan Institute to produce and deliver the vaccine that will most effectively help respond to the public health threat caused by pandemic and seasonal influenza in Brazil."

The A(H1N1) vaccine antigen bulk will be manufactured in Sanofi Pasteur’s facility. Dosage requirements for the new vaccine are yet to be determined and will be based on clinical trial outcomes. Butantan Institute will perform A(H1N1) vaccine’s final formulation, filling and packaging in its Sao Paolo facility (Brazil). Butantan Institute will also be responsible for distributing A(H1N1) influenza vaccine as directed by Brazilian Health Authorities.
