Sanofi-aventis invests €100 million in new facility in Mexico

sanofi-aventisSanofi-aventis (EURONEXT: SAN and NYSE: SNY), has announced the signing of an agreement with the Mexican authorities to build a € 100 million facility to manufacture influenza vaccine in Mexico. The announcement was made during a ceremony attended by Felipe Calderon, President of Mexico, and Nicolas Sarkozy, President of France, who was in Mexico City for a State visit.

This facility will be built and operated by sanofi pasteur, the vaccines division of sanofi-aventis Group, which was represented at the ceremony by Chris Viehbacher, Chief Executive Officer of sanofiaventis.

"By building this new facility, sanofi-aventis is proud to contribute to the strengthening of Mexico's health infrastructure and is eager to support Mexico's exemplary commitment to public health through influenza immunization and pandemic readiness", said Chris Viehbacher. "This investment illustrates sanofi-aventis' local approach to global health. This facility will benefit public health in Mexico and the Latin American region, in the context of influenza pandemic preparedness."

The agreement was signed by Birmex’ (Laboratorio de Biológicos y Reactivos de México) and sanofi-aventis' representatives in the presence of Dr. José Ángel Córdova Villalobos, Minister of Health of Mexico.

Under the terms of the agreement, sanofi pasteur will manufacture influenza vaccine in collaboration with Birmex, a Mexican federal vaccine manufacturer. Birmex will perform certain stages of manufacturing and will be responsible for distributing influenza vaccines to the public in Mexico.

Sanofi pasteur is planning to start construction of the new vaccine manufacturing facility within a few weeks. Upon completion within four years, the facility will have a yearly capacity of up to 25 million doses of seasonal influenza vaccine.

The new influenza vaccine plant will be built in Ocoyoacac, where sanofi-aventis already operates a facility. The plant will be designed to switch to pandemic vaccine manufacturing if a human influenza pandemic is declared and a pandemic influenza strain is identified by the World Health Organization (WHO).

As the world leader in research, development and manufacturing of influenza vaccines, sanofi pasteur is working to develop new and improved influenza vaccines to save lives and is actively involved in pandemic preparedness. Over the last five years, sanofi pasteur has been consistently investing in major expansions of its influenza vaccine production capacity in the United States, France, China, and now Mexico. With the production of more than 170 million doses of seasonal influenza vaccine in 2008, sanofi pasteur confirmed its global influenza vaccine market leadership.

Seasonal influenza overview
Influenza is a disease caused by a highly infectious virus that spreads easily from person to person, primarily when an infected individual coughs or sneezes. According to the World Health Organization (WHO), the average global burden of inter-pandemic influenza may be on the order of 1 billion cases per year, leading to 300,000-500,000 deaths worldwide. In temperate climate zones, seasonal epidemics typically begin in the late Fall and peak in mid-winter, infecting about 5-15% of the population each season, while In tropical zones the virus can be isolated year-round. The disease can affect all age groups, but rates of infections are highest among young children who spread the virus and are a potential source of infection in older age cohorts, whereas rates of serious illness, complications and death are highest in persons aged 65 years and older, as well as in persons with chronic cardiac or respiratory conditions. The efficacy of vaccination in reducing the burden of the disease, as well as the economic burden of treating influenza, is well established.

Pandemic Influenza Overview
Influenza is a disease caused by a highly infectious virus that spreads easily from person to person, primarily when an infected individual coughs or sneezes. An influenza pandemic is a global epidemic of an especially virulent virus, newly infectious for humans, and for which there is no preexisting immunity. This is why pandemic strains have such potential to cause severe morbidity and mortality. In an attempt to minimize the impact of a pandemic, many countries are developing national and transnational plans against a possible influenza pandemic situation.
