TL;DR: It is proved that this classical susceptible-infected-susceptible epidemic model is formulated as a stochastic differential equation (SDE) for the number of infectious individuals and that this SDE has a unique global positive solution.

TL;DR: In this article, the authors investigated the association between the mass roll-out of the first doses of these COVID-19 vaccines and hospital admissions for CoV-19 and found that the first dose of the BNT162b2 mRNA vaccine was associated with a vaccine effect of 91% (95% CI 85-94) for reduced COVID19 hospital admission at 28-34 days post-vaccination.

TL;DR: In this article, a self-controlled case series study was conducted to investigate hospital admissions from neurological complications in the 28 days after a first dose of ChAdOx1nCoV-19 (n = 20,417,752) or BNT162b2 (n= 12,134,782), and after a SARS-coV-2-positive test.

TL;DR: In this article, an association was found between exposure to first-dose ChAdOx1 or BNT162b2 vaccination and hematological and vascular adverse events using a nested incident-matched case-control study and a confirmatory self-controlled case series (SCCS) analysis.

TL;DR: In this article , the authors describe COVID-19 vaccine uptake and SARS-CoV-2 infection in pregnant women in Scotland, using whole-population data from a national, prospective cohort.
