TL;DR: In this article , the authors investigated anti-spike IgG antibody responses and correlates of protection after second doses of ChAdOx1 or BNT162b2 vaccines for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

TL;DR: Several indices were devised, based on linear combinations of the test results obtained, in an attempt to predict the liability to future fractures of patients being considered for prophylactic therapy with oestrogens or other drugs, but further work is required to define an index of improved predictive power and to evaluate it prospectively.

TL;DR: In a nationally representative UK community study, the COVID-19 Infection Survey, the authors investigated symptoms in polymerase chain reaction (PCR)-positive infection episodes versus PCR-negative study visits over calendar time, by age and vaccination status, comparing periods when the Delta, Omicron BA.1, and BA.2 variants were dominant.

TL;DR: The authors evaluated whether a single vaccination in individuals who have already been infected with SARS-CoV-2 generates similar initial and subsequent antibody responses to two vaccinations in those without prior infection.
