Question

multiple choice question
which last longer?

active immunities

passive immunities

Explanation:

Active immunity is developed by the body's own immune response (e.g., from an infection or vaccine), leading to memory cells that provide long - lasting protection. Passive immunity (e.g., from antibodies received externally like in maternal antibodies or immunoglobulin therapy) lasts for a short time as the body doesn't develop memory cells. So active immunities last longer.

Answer:

A. Active immunities
