That is not correct (I think that number comes from the Oxford/AZ vaccine?). If you look at the cumulative incidence curves (for Moderna see [1] page 28), you can see that COVID-19 occurences drop approx. 14 days after the first dose with no measurable effect of the second dose after 28 days. This pattern is exactly the same for both vaccines.

That's slightly disappointing.
