That is not consistent with the "Vaccination status" definition in the paper I cited. The tl;dr on that is that "first dose" starts 21 days after vaccination, and "second dose" 14 days after.

Also, to get a better sense of the timeline for vaccination effectiveness, take a look at a chart like this one: https://www.technologyreview.com/2020/12/10/1013914/pfizer-b...

If you wait 21 days after the first dose, or 14 days after the second dose. Unless everyone had their second dose 7 days after the first one you still don't compare the same thing.

We need something like, 21 days after the first dose, and split the result between people who got one dose and those who got two. We also need to make sure that the repartition of ` age since first dose` is the same for the two doses group and the single dose group.
