TL;DR: There will be relatively long-lived protection from re-infection following symptomatic COVID-19 disease, and there was a high level of correlation between PRNT50 antibody titers and the % of inhibition in surrogate virus neutralization tests.

TL;DR: A recently developed surrogate virus neutralization test (sVNT) is evaluated in comparison to 90% plaque reduction neutralization tests (PRNT90) in human, canine, cat and hamster sera and found excellent concordance between the two assays.
Journal ArticleDOI

TL;DR: There is a need for more studies to investigate whether or not zoonotic transmission of MERS-CoV does take place in Africa, and none of the abattoir workers with exposure to camels had evidence of neutralising antibody to MERS

TL;DR: In this paper, the authors used sera collected from a cohort of 125 individuals with RT-PCR confirmed SARS-CoV-2 infections up to 386 days after symptom onset.
