That relative risk reduction is very signficant, not just statistically signficant, it is very practically signficant too.

Sure, but the sample of confirmed positives is so small that it might not include some important subgroups. If only 1 at risk person in the placebo tested positive, and 0 in the vaccinated group did we haven't learned much.
