For parents: helping your child think about vaccines: how they help your body
"Vaccines: How They Help Your Body" is a strong topic for curious kids ages 7–11. Before sharing facts, ask what your child thinks is happening — guessing first makes the real explanation stick. Pause for their questions; short answers invite more questions than long lectures. When they can explain the main idea back in their own words — without reading — the concept has really landed. That teach-back moment is the same thinking move Whizbee uses: attempt, check, explain. If you are unsure about a detail, say so and look it up together; modelling honest curiosity matters more than pretending to know everything.
