Talk to your grandparents about vaccinations
Until the 1950s, most people never got any vaccinations at all. To see how much kids’ lives have changed because of vaccination, find somebody who was a kid in the 1940s or 1950s (They would be about 65 or 75 years old now – your grandparents might be about the right age).
Ask them about their experiences with measles, mumps, chickenpox, and polio – all diseases that kids your age get vaccinated against now. Ask them whether they got a smallpox vaccination (you did not get one – why not?).
