Biologists isolated the coronavirus nucleoprotein in its pure form to improve the accuracy and sensitivity of the antibody tests

Biologists isolated the SARS-CoV-2 nucleoprotein in its pure form to create more accurate antibody tests. The new approach significantly improves sensitivity, increasing the ability to detect antibodies to the nucleoprotein. This breakthrough helps determine if vaccinated individuals have been infected with COVID-19.

Vaccine protection against SARS-CoV-2 infection wanes quickly but is better maintained against severe disease

A nationwide study in Sweden found that vaccine-induced protection against SARS-CoV-2 infection decreases over time, with most protection lost within seven months. However, protection against severe COVID-19 remains relatively stable, suggesting that booster shots may be necessary to maintain effectiveness.
