Question

Vaccines produce cells that keep a memory of the infection and recruit the immune cells when the same infection happens the second time.

• A. memory
• B. nerve
• C. epithelial

Answer 1

The correct option is A memory

The purpose of vaccination is to fool the immune system so that it fights off an infection immediately, if exposed to, the second time. During the first infection, the immune system produces memory cells to keep a memory of the first attack. When the same infection happens the second time, these memory cells recruit the specific immune cells immediately, to fight the infections.
