In a recent study posted to the medRxiv preprint* server, researchers pursued evidence of whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigens, of which spike (S) protein is ...

Research reveals a sharp decline in both the effectiveness and duration of protection from prior infection post-Omicron, underscoring the need for updated vaccines to sustain immunity Study: ...

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense ...

Two of the closest known relatives to SARS-CoV-2 — a pair of bat coronaviruses discovered by researchers in Laos — may transmit poorly in people despite being genetically similar to the ...

Researchers have discovered that SARS-CoV-2 hijacks three important host proteins that dampen the activity of the complement system, a key component of early antiviral immunity. This significantly ...

The World Health Organization (WHO) announced the prequalification of two rapid antigen diagnostic tests (Ag-RDT) for ...

UCSF researchers designed new drug candidates that potently block MPro, a viral enzyme that's crucial for SARS-CoV-2 replication. One of these drug candidates, AVI-4516, is shown (center) bound to the ...
