What is naturally-acquired active immunity?

A doctor has provided 1 answer

Infection vs vaccine: Naturally acquired immunity happens when you contracted an infection and have become immune as contrasted with vaccinations which also confer active immunity. The innate immune system is something else and refers to mechanisms the body has to fight off or prevent infections starting with barriers like the skin and mucous flow in the respiratory tract.
