Natural immunity is described as?

• A. Disease organism can occur through infection with the actual disease
• B. Immunity from vaccination
• C. Immunity acquired from another person
• D. It is only present in early childhood

Answer: (A)

Natural immunity comes from actually contracting the disease and recovering from it. When your body fights off the infection, it builds specific defenses and memory cells that remember that organism, so you’re better protected if you encounter it again in the future. This is different from immunity gained through vaccination, which protects you without having the disease, and from immunity acquired from another person, which is a transfer of antibodies (passive immunity). It isn’t restricted to early childhood; you can develop natural immunity at any age after recovering from an infection.
