Abstract

SARS-CoV-2 proteins were measured in longitudinal plasma samples collected from 13 participants who received two doses of mRNA-1273 vaccine. 11 of 13 participants showed detectable levels of SARS-CoV-2 protein as early as day one after first vaccine injection. Clearance of detectable SARS-CoV-2 protein correlated with production of IgG and IgA.

Imagination and remembrance: what role should historical epidemiology play in a world bewitched by mathematical modelling of COVID‑19 and other epidemics?

April, 2021

Abstract

Although every emerging infectious disease occurs in a unique context, the behaviour of previous pandemics ofers an insight into the medium- and long-term outcomes of the current threat. Where an informative historical analogue exists, epidemiologists and policymakers should consider how the insights of the past can inform current forecasts and responses.
