- Conscientious Refusers--people who reject all vaccination, like conscientious objectors in wartime reject all fighting. They usually have religious reasons.
- Critical Refusers--people critical of mainstream science and medicine. They will go on thinking vaccines cause autism (for example) no matter how many studies show otherwise.
- Doing/allowing Refusers--they see a problem with doing something that stands a chance of causing serious side effects, but see no problem with allowing a child to be infected with a vaccine-preventable disease. Unlike those in group 1, they would accept a vaccine with no associated risks.
- You-first Refusers--people who think enough other people are vaccinating their children so that they don't have to. In the early days of a vaccine, when herd immunity doesn't exist yet, they will vaccinate their children. In the late days, when they think herd immunity protects their children sufficiently, they opt out.
But who thinks like a You-first refuser? Aren't real world vaccine refusers all in groups 1 and 2? In fact, a popular author outright welcomes his readers to be You-first refusers. Here's a delicious/horrifying passage from The Vaccine Book, by Robert Sears, MD.
