That is a dramatic misrepresentation of that preprint. The number of deaths is small enough that it is hard to draw inferences from it, and that was not the endpoint of the study. Rather, the key finding is a vaccine effectiveness of 97% against severe disease.

A preprint that did address deaths[1] found a vaccine effectiveness of 98.7% against death. This is not consistent with your claim of "no evidence."
