MICROANATOMY

Detailed explanation-1: -Measles vaccine induces both humoral and cellular immune responses. Antibodies first appear between 12 and 15 days after vaccination and peak at 21–28 days. IgM antibodies appear transiently in blood, IgA antibodies are predominant in mucosal secretions, and IgG antibodies persist in blood for years.

Detailed explanation-2: -Passive Immunization. Passive immunity to measles can be acquired through physiologic transfer of maternal measles antibodies from mother to child or by administration of immunoglobulin preparations containing measles antibodies to persons at risk of measles.

Detailed explanation-3: -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.

Detailed explanation-4: -Artificial active immunity refers to immunity produced by intentional exposure of a person to antigens to produce antibodies and memory cells. For example, the administration of vaccination often leads to artificial active immunity.
