ACAM2000

ACAM2000®, (Smallpox (Vaccinia) Vaccine, Live) is a live, vaccinia virus smallpox vaccine licensed in the U.S. by the Food and Drug Administration for active immunization against smallpox disease for persons determined to be at high risk for smallpox infection. It was developed by Sanofi Pasteur Biologics, LLC (formerly Acambis) under a contract with the U.S. Centers for Disease Control and Prevention (CDC).

ACAM2000 vaccine was developed to be a licensed smallpox vaccine manufactured using modern cell-culture techniques complying with current Good Manufacturing Practice standards. Production of first-generation vaccines ceased in the early 1980s following a successful smallpox vaccination campaign by the World Health Organization that led to the declared eradication of smallpox in 1980.

Today, ACAM2000 vaccine is the primary smallpox vaccine for use in a bioterrorism emergency and forms the majority of the U.S. Government's smallpox vaccine stockpile. Sanofi Pasteur Biologics, LLC has supplied more than 196 million doses of ACAM2000 vaccine to the US Government for its Strategic National Stockpile. Sanofi Pasteur Biologics, LLC has also supplied ACAM2000 vaccine under an FDA Investigational New Drug application to several other governments around the world.

About Smallpox

About SmallpoxSmallpox is a highly contagious disease caused by the variola virus, a member of the Orthopox virus family. It is one of the most devastating diseases known to humanity, with a mortality rate as high as 30%.

In 1967, the World Health Organization embarked upon an intensified vaccination campaign to eradicate smallpox, which culminated in the successful eradication of the disease globally by 1980.1

By the mid-1980s, there were only two known repositories of variola virus: the Institute of Virus Preparations in Russia and the US Centers for Disease Control and Prevention (CDC). The events in the U.S. in September and October 2001 highlighted the risk that the variola virus might be used as an agent of bioterrorism.2 Governments around the world are taking precautionary measures to be ready to deal with a potential smallpox outbreak.
