(Sanofi Pasteur Biologics, Lyon, France), the currently licensed vaccinia vaccine, for laboratory workers at national variola testing sites or perhaps an even broader population of laboratory workers throughout the United States.
Another example is also the Acambis ACAM2000
smallpox vaccine which is made in a Vero cell line using disposable production technology.
Vaccinia virus was confirmed in all four patients, and gene sequencing in three of the cases linked the virus to the ACAM2000
The Food and Drug Administration has approved a new smallpox vaccine, ACAM2000
, for active immunization against smallpox in individuals determined to be at high risk for smallpox infection.
In May, the Food and Drug Administration's Vaccines and Related Biological Products Advisory Committee voted 11-0 in favor of both the safety and efficacy of the vaccine, marketed as ACAM2000

The second-generation vaccine is ACAM2000
(Acambis, Cambridge, MA, USA), which is a plaque-purified distinct strain of New York City Board of Health vaccinia virus grown by using modern cell lines rather than the skin of calves.
(Smallpox (Vaccinia) Vaccine, Live) vaccine for active immunization against smallpox disease for persons determined to be at high risk for smallpox infection was licensed by the US Food and Drug Administration in August 2007.
