You know, it’s not so much that vaccine apologists and simpleton proponents have the science wrong with regard to vaccines (… although, of course, they do). The more central problem is that they got the history wrong to begin with. Which, in turn, leads to the science being distorted and corrupted. If you get the history wrong (… and this applies to any field of knowledge), then you relegate yourself to ignorance and leave yourself wide open to manipulation. You failed history big time, which is why you are so miserably informed about vaccines. Have a cup of coffee and start over.
Sorry, “F” on vaccine history. Do over.
