Question

1. 7. the temporary immunity an infant acquires from its mother is called?

a. vaccine
b. vaccination
c. active immunity
d. passive immunity

Explanation:

To solve this, we analyze each option:

• Option a: A vaccine is a substance for inducing immunity, not the immunity type here.
• Option b: Vaccination is the act of administering a vaccine, not the immunity.
• Option c: Active immunity is when the body produces antibodies (e.g., from infection or vaccine), not acquired from the mother.
• Option d: Passive immunity is acquired from an external source (like a mother’s antibodies), which matches the infant’s temporary immunity from the mother.

Answer:

d. Passive immunity
