TL;DR: A post-hoc analysis of the efficacy of the adenoviral vector vaccine, ChAdOx1 nCoV-19 (AZD1222), against B.1.7, emerged as the dominant cause of COVID-19 disease in the UK from November, 2020 as discussed by the authors.

TL;DR: In this paper, the authors assessed the persistence of immunogenicity after a single dose of ChAdOx1 nCoV-19 (AZD1222), immunity after an extended interval (44-45 weeks) between the first and second dose, and response to a third dose as a booster given 28-38 weeks after the second dose.
