Novel biosensor offers rapid quantitative variant of concern-independent serology for SARS-CoV-2

Even as herculean efforts are being made to extend the reach of vaccination against COVID-19 to all the regions of the world, there is a dire need for rapid and sensitive tests to assess the antibody response to the various vaccines used and to monitor antibody titers over time. A new preprint describes a new approach to this problem which could be applied to other molecules of interest as well, both in laboratories and at the point of care.

Indian WHO study examines COVID-19 susceptibility in children versus adults

Now, a group of researchers from India have explored this concept due to the lack of solid evidence and have undertaken a community and population-based serosurveillance study for the coronavirus infection under the World Health Organisation (WHO) Unity umbrella. In this study, participants older than two years old were compared to older adults in terms of seropositivity.
