Vaccination and You
The info in this book is not that bad. It is geared to upper age elementary and it is pretty basic. It is simple enough that even some US governors, senators, and other leaders could grasp the concepts. With an update and more modern illustrations, this could work in 2021.
The photographs used were actually interesting. They also used a painting for the Louis Pasteur pages. Mrs Pasteur seems to be lurking in the hallway by his lab. Instead of a citation for the painting, there is a note that Mrs Pasteur is patiently waiting. (A quick search identified the artist as Robert Thom. This was from a group of paintings commissioned by Parke-Davis, later donated to the University of Michigan. You can see the collection uploaded here.)
