Pandemic-stage propagation dynamics in South Africa suggest pre-existing cross-reactive protection against severe Covid-19

2021-04-15

Abstract excerpt

<title>Abstract</title> <p>Early in the Covid-19 outbreak, it was speculated that pre-existing cross-reactive immunity from prior BCG vaccination or exposure to common cold human coronaviruses might confer some protection against Covid-19. Following a year of circulation of SARS-CoV-2 through the world, epidemiological dynamics allow a test of this hypothesis. A dynamic epidemiological model was fitted to the Cov...
