Multiple choice

Which type of immune response is responsible for providing long-term protection against infection?

  1. Humoral immune response

  2. Cell-mediated immune response

  3. Innate immune response

  4. Adaptive immune response
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The adaptive immune response is responsible for providing long-term protection against infection. It involves the activation of memory cells, which can quickly respond to a pathogen that the body has encountered before.
