Children get the virus, but don´t become sick, so risk is still small compared to the vaccine risk.

Children do become sick from the virus, but they are at less risk than adults so far. But you've missed my point, which is response to the point from @edprivat: if the primary risk from the vaccine is the introduction of the spike protein, then that risk is much less from the vaccine than from covid which also exposes them to the the spike protein (and in larger quantities).

If you want to argue there is some other potential but yet ukknown issue with the vaccine, you can make that argument, but there is no evidence for a risk of this type right now. With the low number of adverse reactions so far, you would have to make an argument for some long term issue that hasn't yet been detected (I think Malone mentioned the lack of long term fertility-related studies, for example). But I'm specifically addressing the issue of the spike protein concern.

in reality the virus always escapes the vaccine

There are many illnesses that we have effectively wiped out using vaccines. This is not just some made-up claim by vaccine companies. If you want to argue that vaccines never work, then I'm not sure we can hold a productive conversation, because we're starting from very different view points as to established facts.
