The two dose studies provide incomplete information about the single dose efficacy — administration of the second dose ends the data collection for the first dose alone.

The data collection also includes the period of time that the body spends responding to the vaccine (so if you get the shot and get infected that day, the shot gets counted as not being effective).

And then on the other side of it, they don't have data on how long immunity from a single dose would last.

But it's likely that the Moderna and Pfizer vaccines have quite high effectiveness after the initial immune response.

Sure, while it's not perfect, the data for those 3 weeks between the first and second shot still can provide a lower bound approximation for immunity, which I assume is where the 60% comes from.

The point about how long single dose immunity lasts is fair though.
