The Immune System and Vaccination — Interactive Lesson (Ages 14–16)

Your body fights germs every day. Teach how its defences work, and how vaccines prevent disease. This 21-slide interactive lesson on vaccination takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching The Immune System and Vaccination in GCSE Biology

Pupils describe the body's non-specific defences — skin, mucus, cilia and stomach acid — and three ways white blood cells destroy pathogens: phagocytosis, antibodies and antitoxins. They explain why antibodies are specific to antigens, how vaccination with a dead or inactive pathogen leads to immunity, and how herd immunity protects a whole community, with Nigeria's polio campaign as an example.

What Pupils Will Learn

• Describe the body's non-specific defences.
• Describe three ways white blood cells destroy pathogens.
• Explain why antibodies are specific to antigens.
• Explain how vaccination prevents illness.
• Explain how vaccinating many people protects a whole community.
