Diphtheria Toxoid

Diphtheria toxoid (DTd) is prepared by formaldehyde inactivation of purified diphtheria toxin. Inactivated bacterial toxins, including DTd, are widely used as protein carriers chemically conjugated to oligosaccarides in licensed vaccines, which induce a more robust immune response against the carbohydrate.
