History of Vaccines
As you follow the anti-vaccine movement from the very beginning, it is easy to see the common threads that connect all of the players from the Victorian Age to the 21st Century. Germ theory denialism. Alternative medical providers. The media. What else? Fear, especially fear of vaccine-injury.
From historical safety concerns, like the Cutter Incident in 1955 or the withdrawal of the first rotavirus vaccine in 1999, to improvements in vaccine safety and the control, elimination, and eradication of vaccine-preventable diseases, understanding the history of vaccines can help you understand how important vaccines really are to us all.
