Ebola survivors’ antibody levels against the disease wax and wane over time, according to new research that has important implications for tracking variable immunity to other viruses,

A monoclonal antibody drug combo showed promise in lowering viral loads in early-stage COVID-19 outpatients,

Doctors say they help. So why are COVID-19 treatments—including monoclonal antibodies, antivirals, and corticosteroids—going unused?

A new Lancet study—the longest term follow-up study so far—offers a snapshot of COVID-19 symptoms 6 months after symptoms onset.  

SARS-CoV-2 antibodies wane over time, and more severe cases stir stronger immune responses, a trio of new studies concur. And while they diverge over how long antibodies last, this isn’t necessarily cause for concern.

This is good news: A cocktail of synthetic antibodies has shown promising, early results for beating back the coronavirus in patients that aren’t yet seriously ill.  

The nearly 1 million people lost to COVID-19 represent an immense tragedy—but they left the world an incredible gift: life-saving insights into treatments, 

A flurry of research is identifying patterns that set apart COVID-19 patients who are prone to deadly immune system overreactions. During these “cytokine storms,” molecules leading the first line of immune defense fail to stand down so that antibodies and T cells can take…

While the world awaits a vaccine, drugmakers—and the US government—are throwing resources behind a potential stop-gap solution: custom antibodies designed to fight COVID-19.   Grown in bioreactor vats, these monoclonal antibodies are copies of naturally occurring proteins…

Some people who have not been exposed to SARS-CoV-2 may still have some immunity to it—and not because they have antibodies.
