Survey reveals impact of Pfizer-BioNTech vaccination in the UK

Researchers at Imperial College London in the UK have reported on round five of the REal-time Assessment of Community Transmission-2 (REACT-2) program – a cross-sectional community survey measuring the prevalence of antibodies against the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among adults in England.

Researchers evaluate surrogate large-scale SARS-CoV-2 serosurveillance test

A team of international scientists has recently evaluated a surrogate virus neutralization test for severe acute respiratory coronavirus 2 (SARS-CoV-2) and observed that it is highly efficacious for detecting anti-SARS-CoV-2 neutralizing antibodies in serum samples. According to the scientists, the test can be effectively used for population-level serosurveillance and evaluation of vaccine efficacy. The study is currently available on the medRxiv* preprint server.
