This is an interesting map from Every Child By Two which is a pro-immunization advocacy group. And, per the article in USA Today, this discussion around vaccines is heating up with kids coming back to school and the biggest epidemic of whooping cough in 50 years.
I’ll also pull up this video that I posted last year which I thought to be a fun presentation of this topic.
Enabling Healthy Decisions 
The video is very funny.
It never ceases to amaze. The general public does not understand math….for if they did, the map you posted would not exist. Go Public Health!
