Global toxoid vaccines market is segmented into product, end-users and geographic regions. Toxoid vaccine is a vaccine made from a toxin (poison) that has been made nontoxic but that elicits an immune response alongside the toxin. They are based on the toxin shaped by certain bacteria (e.g. tetanus or diphtheria). The toxin invades the bloodstream and is principally responsible for the symptoms of the disease. The protein-based toxin is rendered nontoxic (Toxoid Inactivated or killed toxin (poison) used in vaccine production.) and used as the antigen in the vaccine to elicit immunity. To augment the immune reaction, the toxoid is adsorbed to aluminum or calcium salts, which serve as adjuvant.
