Moderna vaccine reduced viral load and protected against SARS-CoV-2 variants in new phase 3 trial

Coronavirus research has shown that higher viral loads are associated with severe COVID-19 infection. But new results from the phase III Coronavirus Efficacy (COVE) clinical trial find the Moderna vaccine reduces severe acute respiratory coronavirus 2 (SARS-CoV-2) viral load and viral shedding.

SARS-CoV-2 nucleocapsid antigen as a possible COVID-19 severity marker

French researchers used a highly sensitive and specific nucleocapsid-Ag assay to explore the relationship between N-Ag in urine during COVID-19 and the severity of the disease in hospitalized patients.
