It is nonsense to vaccinate young and very healthy people, especially kids. Their risk from COVID is minimal to non-existent.
Also the spread is not stopped by vaccinating. Vaccinated still spread the virus. If it is reduced is still unclear. There was a study in GB that showed the incidence numbers in vaccinated was just as high or higher than in unvaccinated. The sample sizes of vaccinated and unvaccinated were equal as they should be. Reports in Germany about these numbers forget to mention that vaccinated people are basically not tested.

They do not work well enough. First of all people still transmit the virus after only about 2 months after the vaccination. Then the protection goes down extremely between 2-6 months after the vaccination (that is why we need boosters all the time). It is still unclear if we continue to need boosters after the third shot.
