TL;DR: In this article, the authors examined the proportion and probability of self-reported systemic and local side-effects within 8 days of vaccination in individuals using the COVID Symptom Study app who received one or two doses of the BNT162b2 vaccine or one dose of the ChAdOx1 nCoV-19 vaccine.

TL;DR: In this article, the authors identify risk factors for post-vaccination SARS-CoV-2 infection and describe the characteristics of post-vaccination illness, using self-reported data from UK-based, adult users of the COVID Symptom Study mobile phone app, including demographics, geographical location, health risk factors, and COVID-19 test results, symptoms, and vaccinations.
Journal ArticleDOI
Symptom prevalence, duration, and risk of hospital admission in individuals infected with SARS-CoV-2 during periods of omicron and delta variant dominance: a prospective observational study from the ZOE COVID Study
Cristina Menni,Ana M. Valdes,Lorenzo Polidori,Michela Antonelli,Satya Penamakuri,Ana Nogal,Panayiotis Louca,Anna May,Jane C. Figueiredo,Christina Hu,Erika Molteni,Liane S Canas,M F Österdahl,Marc Modat,Carole H. Sudre,B. Fox,Alexander Hammers,Jonathan Wolf,Joan Capdevila,Andrew T. Chan,Sean Davis,Claire J. Steves,Sebastien Ourselin,Tim D. Spector +23 more
TL;DR: The prevalence of symptoms that characterise an omicron infection differs from those of the delta SARS-CoV-2 variant, apparently with less involvement of the lower respiratory tract and reduced probability of hospital admission.
Journal ArticleDOI
Changes in symptomatology, reinfection, and transmissibility associated with the SARS-CoV-2 variant B.1.1.7: an ecological study.
Mark Graham,Carole H. Sudre,Anna May,Michela Antonelli,Benjamin J. Murray,Thomas Varsavsky,Kerstin Klaser,Liane S Canas,Erika Molteni,Marc Modat,David A. Drew,Long H.

TL;DR: In this paper, an ecological study was conducted to examine the association between the regional proportion of infections with the SARS-CoV-2 B.1.7 and reported symptoms, disease course, rates of reinfection, and transmissibility.
Journal ArticleDOI
