Question

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

• A. Active immunity
• B. Passive immunity
• C. Cellular immunity
• D. Innate nonspecific immunity

Answer 1

Answer: (B)

Passive immunity

Answer 2

Short-lived immunity acquired from mothers to foetus across placenta or through mother's milk to the infant is categorised as passive immunity. Passive immunity, an acquired immunity, is resistance based on antibodies performed in another host. In this case, the foetus is not directly responsible for its body immunity but it becomes immunised by mother's milk across placenta.
