What does “passive immunization” mean?
passive immunization
Oh, this is a cool science phrase!
So normally, your body learns to fight a sickness by meeting the germ itself — that takes time. But "passive immunization" means you get protection from the outside — like someone gives you ready-made defenders (called antibodies) directly into your body.
Think of it like this: instead of learning to cook a meal yourself, someone just hands you the finished dish. You're protected right away, but it doesn't last forever because your body didn't make those defenders itself.
Doctors use this when someone needs help fast — like after a snakebite, they might give you something with ready-made fighters to stop the poison quickly. Or babies get it naturally from their mother's body before they're born.
So basically — it's borrowing someone else's protection instead of building your own.
