One other thing about the vaccine trial is that the trial screened for asymptomatic infections, not just symptomatic infections as the Moderna and Pfizer/BioNTech trials did, so the comparisons are a bit apples-to-oranges:

This will be interesting to follow.  If the Oxford/AZ vaccine protects against asymptomatic infections, at a 70% rate it is still possible that protection against symptomatic infections will be better. We actually don't know if the Moderna and Pfizer/BioNTech vaccines reduce asymptomatic transmission at all (though it is assumed they do).
