Many cannot produce enough infection-fighting cells to fend off the coronavirus. But researchers are testing one therapy that may help: monoclonal antibodies.
Growing evidence suggests that people with cancer and other conditions that challenge their immune systems may be incubators of mutant viruses.
New research found ‘autoantibodies’ similar to those in lupus and rheumatoid arthritis patients. But patients may also benefit from treatments for those autoimmune diseases.
Reports of reinfection instead may be cases of drawn-out illness. A decline in antibodies is normal after a few weeks, and people are protected from the coronavirus in other ways.
Antibodies to the virus faded quickly in asymptomatic people, scientists reported. That does not mean immunity disappears.
A team of scientists worked around the clock to evaluate 14 antibody tests. A few worked as advertised. Most did not.
