Immunity & Vaccines
Distinguish innate (non-specific, immediate) from adaptive (specific, memory-forming) immunity; explain how B cells produce antibodies that recognise specific antigens, how T cells destroy infected cells, and why immunological memory makes vaccines work; and describe the gut microbiome as a community of trillions of microbes that significantly influences immune function

Check understanding
- Distinguishes innate immunity (rapid, non-specific barriers and inflammation) from adaptive immunity (slow, specific, memory-forming)
- Explains how B cells produce antibodies that bind to specific antigens on pathogens, targeting them for destruction
- Explains immunological memory: after first exposure, memory B and T cells remain, making subsequent response faster and stronger — the basis of vaccine protection
“If your child was asked why they don't get chickenpox twice, could they explain the difference between just fighting off a germ and actually 'remembering' it — and describe how a vaccine trains the immune system without causing the disease?”
