What is Impact of Vaccination on Human Health about?

The printing press was one of the most significant inventions in history. Before it was invented, monks had to hand write books, so only a few people could access information and only the very rich could afford books. The printing press, invented by Johannes Gutenberg in the 1440s, allowed text to be reproduced in large quantities efficiently using movable type. This caused knowledge to become widely available for the first time and greatly impacted the world by disseminating information on a mass scale.
