The results in the paper are not statistically significant. It is measuring non stat sig tail events from the trial. The only statistically significant result is the 95% efficacy of the vaccine. This paper compares serious hospitalizations in the placebo group versus side effects in the treatment group, neither of which has stat sig data. In particular the number of covid19 infections/exposure in the 4 month period were small, a couple of hundred, whereas the vaccine exposure was 10K+. The paper simply ignores basic normalization of the data for exposure.
