Immunity & Vaccines
Your child can explain why you do not catch chickenpox twice. After the first time, the body remembers the germ. A vaccine builds that memory without making you ill.
In curriculum terms
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

Try this together
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?
