A unique and rapid SARS-CoV-2 surrogate virus neutralisation test (sVNT) may be the much needed boost to current COVID-19 investigations to determine infection rate, herd immunity, predicted humoral ...

A recent study by US researchers, currently available on the medRxiv* preprint server, evaluated several cell-based assays that are under validation for determining correlates of protection in ...

Emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern pose a challenge to the effectiveness of current vaccines. A vaccine that could prevent infection caused by ...

Evaluation of a 'plaque reduction neutralization test'. Using blood samples from COVID-19 patients, this test detects the antibodies which neutralize the SARS-CoV-2 virus, i.e. stop the virus ...

SARS-CoV-2 vaccine efficacy testing is now facing increasing challenges in the face of an ongoing pandemic with the emergence of new variants and waning vaccine immunity. Evidence supports the ...
