In general, I like this show. In particular, I liked the effort to help people understand how immunization works. I am an old man. Some 60+ years ago, I watched a short film designed to achieve the same results. It was a simple but highly explicit short movie which showed how an infectious disease might behave, first in a non-vaccinated child and then in a vaccinated one. Perhaps the film is so old that nobody remembers it, but even now, it could be very helpful.
