Biology Year 12 - Module 7 - Lesson 13
Primary and Secondary Immune Response
1. Key Ideas
In 1796, Edward Jenner noticed that milkmaids who caught cowpox never seemed to get smallpox. He didn't know about B cells, T cells, or memory lymphocytes. He just noticed the pattern — and acted on it. The mechanism he accidentally discovered is the same one behind every vaccine ever made.
- What happens during the primary immune response
- Why the secondary response is faster and stronger
2. Success Criteria
By the end, you should be able to:
- What happens during the primary immune response
- What happens during the secondary immune response
- The role of memory cells in both B and T cell responses

5. Short Answer Questions
1. Explain this lesson goal in your own words: "What happens during the primary immune response". Use one specific example from the lesson.
2. Apply this idea to a new example: "What happens during the secondary immune response". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Primary and Secondary Immune Response: "The role of memory cells in both B and T cell responses".
6. Extend: Apply the Idea
A student gives a memorised answer about Primary and Secondary Immune Response but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
