Detailed explanation-1: -Toxoid is a type of vaccines obtained from the toxin and are inactivated and made harmless by chemical or heat treatment. Eg-tetanus toxoid is obtained by Clostridium tetani. These vaccines provide artificial active acquired immunity. So, the correct answer is ‘Artificial active acquired immunity’.
Detailed explanation-2: -Toxoid vaccines use a toxin (harmful product) made by the germ that causes a disease. They create immunity to the parts of the germ that cause a disease instead of the germ itself. That means the immune response is targeted to the toxin instead of the whole germ.
Detailed explanation-3: -Active artificially acquired immunity refers to any immunization with an antigen. By giving a safe form of the antigen artificially, the body will produce its own antibodies and, more importantly, develop circulating, long-lived B-memory cells with high affinity B-cell receptors on their surface.
