Explanation:
Detailed explanation-1: -Natural immunity is acquired from exposure to the disease organism through infection with the actual disease.
Detailed explanation-2: -Active immunity is usually classified as natural or acquired. Wild infection for example with hepatitis A virus (HAV) and subsequent recovery gives rise to a natural active immune response usually leading to lifelong protection.
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.
