sodium chloride + yellow fever virus strain 17d-204 live antigen

This product is a **combination formulation** consisting of live attenuated **yellow fever virus strain 17D-204 live antigen** together with its accompanying **sodium chloride diluent** used for reconstitution prior to administration. It corresponds to the YF-VAX presentation supplied as a lyophilized live-virus vaccine plus preservative-free sterile sodium chloride injection. The biologically active component is the 17D-204 yellow fever vaccine virus, a live attenuated flavivirus antigen developed by **Sanofi Pasteur** to prevent **yellow fever**. After administration, the vaccine induces humoral and cellular immune responses, with protective activity primarily associated with generation of neutralizing antibodies against yellow fever viral envelope antigens. The sodium chloride component functions as a reconstitution diluent rather than as a therapeutic active ingredient.
