Short-lived immunity acquired from mother to foetus across placenta or through mother's milk to the infant is categorised as :-

  1. Passive immunity
  2. Cellular immunity
  3. Innate non-specific immunity
  4. Active immunity

Answer

(1) Passive immunity

Solution

As per NCERT, when ready-made antibodies are directly given to protect the body against foreign agents, it is called passive immunity.

⇒ The yellowish fluid colostrum secreted by the mother during the initial days of lactation has abundant IgA antibodies to protect the infant.

⇒ The foetus also receives some antibodies from the mother through the placenta during pregnancy.

∵ The infant does not make these antibodies itself, the protection is short-lived.

∴ It is passive immunity.
