Here's a medical book from the 19th Century. It seems vaccination has been controversial for a long time.
This interests me because it removes many of the standard arguments pro vaxxers use to try and dismiss concerns about vaccination. The authors was not 'brainwashed by fraudulent studies', he was not 'a woo obsessed conspiracy theorist' and he was almost certainly not 'influenced by Putin'.
People have been awake to the dangers of vaccines for many years. All that's left is for the free thinking people of the world to seize the narrative and show people the truth. Perhaps we could start with the statistics in this book....
