ANATOMY

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: -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-3: -Passive immunity is the administration of antibodies to an unimmunized person from an immune subject to provide temporary protection against a microbial agent or toxin. This type of immunity can be conferred on persons who are exposed to measles, mumps, whooping cough, poliomyelitis, …

Detailed explanation-4: -Vaccines contribute to active immunity by providing us with a controlled way to create an immune response. When a vaccine is introduced, our immune system treats it like any other exposure.
