Rebecca DuBois, associate professor of biomolecular engineering at UC Santa Cruz, said the new method her team developed […]

Antibodies to SARS-CoV-2 are detected up to 3 months after infection

A new study in health care workers led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by “la Caixa” Foundation and the Hospital Clínic of Barcelona, shows that IgA and IgM antibodies to SARS-CoV-2 decay quickly, while IgG antibody levels are maintained for at least three months after infection. The longer follow-up […]

What are monoclonal antibodies? (And why do we need them?)

When President Trump was diagnosed with COVID-19, one of the cutting-edge experimental therapies he received was a mixture of monoclonal antibodies. But now a vaccine may soon be available. So are other therapies necessary or valuable? And what exactly is a monoclonal antibody? Over the past few months, the public has learned about many treatments being used to combat COVID-19. An antiviral […]

Preexisting antibodies targeting SARS-CoV-2 discovered in small proportion of uninfected individuals

Scientists have detected preexisting antibody-driven immunity against SARS-CoV-2 in a small proportion of individuals who were uninfected at the time of sampling. Sixteen out of 302 adults (5.3%) harbored IgG antibodies that were likely generated during previous seasonal “common cold” coronavirus infections, and which cross-reacted with subunit S2 of the SARS-CoV-2 spike protein complex. Notably, […]

Scientist develops new way to test for COVID-19 antibodies — ScienceDaily

When Dr. Stephen Smith of Seattle Children’s Research Institute came down with muscle aches, gastrointestinal distress and a sudden loss of smell in late February, he suspected he had COVID-19. The testing criteria had yet to be expanded to include individuals with Smith’s symptoms and so he did what many scientists with his expertise would […]

In recovering COVID-19 patients, antibodies fade quickly

Washington, DC – October 16, 2020 – In the absence of approved, effective treatments for COVID-19, some hospitals have been treating patients with severe COVID symptoms with blood plasma from recovering patients. The blood of recovered patients contains antibodies that act against the coronavirus. While plasma hasn’t yet shown a benefit in randomized trials, some […]
