Details are. The scientist used the manufacturer's own studies and added up all problems caused by the vaccines in their studies data. When you use the metric "all problems and morbidities" its clear that the vaccines cause more severe problems than they help. The vaccine makers instead used the metric "prevents severe covid infection" which is the wrong metric to use because that excludes all the non covid problems the vaccines cause. Additionally even using the "prevents severe covid infections" metric the vaccines prevent a very small number of severe covid infections...like 6 out of 20,000. The manufacturer's want you to only count the good which is slight. That would be like continuing to use thalidomide because the manufacturer's want you to only notice it reduces nausea in pregnant women and exclude the fact that it causes arm less and legless babies.
