Vaccines are Aventis Pasteur's area of expertise. Because of this, today we are able to provide the widest range of vaccines, protecting against 20 bacterial and viral diseases, including pertussis, diphtheria, typhoid fever, poliomyelitis, influenza and mumps.

Combination vaccines (several antigens in a single injection) are one of the strengths of Aventis Pasteur's product range. They offer the advantage of simplifying immunization schedules, decreasing costs, and ensuring better comfort.

Thymoglobulin is a pasteurized anti-thymocyte rabbit immunoglobulin that induces immunosuppression as a result of T-cell depletion and immune modulation. Thymoglobulin is made up of a variety of antibodies that recognize key receptors on T-cells, the cells of a transplant recipient's immune system that recognize and ultimately reject foreign objects such as transplanted organs. While the exact mechanism is unknown, researchers believe Thymoglobulin antibodies may inactivate and kill these T-cells, thus neutralizing the rejection process and allowing the transplanted organ to recover. Thymoglobulin is also used to treat aplastic anemia and steroid resistant GVHD. Thymoglobulin is approved in the U.S. only for treatment of kidney transplant acute rejection episodes.
