MICROANATOMY

Detailed explanation-1: -Artificially acquired active immunity is protection produced by intentional exposure of a person to antigens in a vaccine, so as to produce an active and lasting immune response.

Detailed explanation-2: -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-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.

Detailed explanation-4: -Active Immunity-antibodies that develop in a person’s own immune system after the body is exposed to an antigen through a disease or when you get an immunization (i.e. a flu shot). This type of immunity lasts for a long time.
