Should be 'at least one dose'. I don't see a reason to treat 'one dose of Moderna' as categorically unlike 'one dose of J&J'.
In all cases of ambiguity, I'm assuming Scott Alexander's the arbiter -- these are really predictions about what Scott will judge the answer to be come end-of-2021.
Scott Alexander makes yearly predictions on SSC/ACX. This year, I avoided looking at his blog post so I could make my own unanchored predictions about the same topics, using a copy of the post with Scott's probabilities removed. Then I looked at his and others' numbers, to see how much they update me.
For each question...
My numbers were influenced a lot by the fact that I expect to round to the nearest 10% (or to 1% / 5% / 95% / 99% at the extremes) to check calibration.
