If unvaccinated people all died or went to the hospital it would be impressive, the title is misleading or lying about it’s effectiveness. The null hypothesis would probably neutralize it’s effectiveness. They don’t use infection prevention which would be much higher for unvaccinated because in reality it’s probably not very effective against COVID. The control we also don’t know any statistics about.
This is a placebo-controlled trial. The statistical comparison shown (85% fewer hospitalizations & deaths in the treatment group) already takes into account the non-hospitalized cases in the control group.
