Will Antibodies After COVID-19 Illness Prevent Reinfection?
Scientists don't know whether people who have been exposed to the coronavirus will be immune for life, or if it can infect us again and again, like the common cold.

Antibody Tests For Coronavirus Can Miss The Mark
Antibody tests to detect past exposure to the coronavirus will soon be everywhere. But even the best ones can provide wrong answers surprisingly often — and give false assurance.
How A Coronavirus Blood Test Could Solve Some Medical Mysteries
Researchers in Asia are using a blood test that identifies people who have previously been exposed to the new coronavirus. In the U.S., that kind of test isn't yet available.
An Antibody-Inspired Small Molecule Could Make For A Better Flu Treatment
To outsmart influenza, researchers are leveraging the biological information encoded in infection-fighting antibodies to design new drugs. One attempt neutralizes near-lethal levels of flu in mice.
Flawed Research Tool Leads To Faulty Medical Findings
Just as natural antibodies help your body find and fight microbial invaders, tailored research antibodies let scientists target and study cancer cells. But too many are poorly made, scientists say.
How Many Viruses Have Infected You?
Most tests for viruses aim to detect only one or two. But researchers can now check a drop of blood for antibodies to hundreds of viruses, tracing the history of a lifetime of infections, old and new.
