I have seen speculation that the effect was derived from changing behaviour among those who received a booster.
Anyway, even the study above ( which is better outlined in the NYT) recommends third vaccines for the immuno-compromised. |
Antibody response after a booster dose (beyond the 1st) is normally quite quick. The 2nd dose of the mRNA vaccines got about 90% of the way to their peak efficacy within a week of being administered, so I don't think it's implausible that the same would happen with the 3rd. And they monitored beyond the 7 days, and the effect continued (improved, actually).
There are confounding variables (as there are with almost any real-world study), but I think the effect is pretty clear.
