Question

Immunity provided to a baby through colostrum is an example of:

Options
  • A

    Natural Active Immunity

  • B

    Artificial active immunity

  • C

    Natural passive immunity

  • D

    Artificial passive immunity

Explanation

Colostrum is the first milk produced by a mother after giving birth, and it contains a high concentration of antibodies that provide immunity to the newborn. These antibodies are passed from the mother to the baby through the colostrum, providing protection against infections.

Incorrect, as natural active immunity involves the production of antibodies by the individual in response to exposure to an antigen.

Incorrect, as artificial active immunity involves the intentional exposure to an antigen, such as through vaccination, to stimulate an immune response.

Colostrum is the first milk produced by a mother after giving birth, and it contains a high concentration of antibodies that provide immunity to the newborn. These antibodies are passed from the mother to the baby through the colostrum, providing protection against infections.
