Unfortunately the compensation scheme doesn't really seem to work that well.
In the States vaccine compensation was paid by vaccine manufacturers (not sure whether it still is) by way of a levy per shot given. The more dangerous the shot the more the companies paid into the fund. So they paid more per MMR shot than DT for example (and more for DTP than DT).
If 'everyone knows' that vaccines can damage then it's shocking that these things take nearly 2 decades for payment. What I find happens is that everyone knows theoretically - when it actually happens mother (always the mother) is accused of being in denial or imagining things.
Really any potential vaccine injury is meant to be investigated. They rarely are.
