Antibodies against COVID-19 vary with vaccination vs natural infection

August 27, 2021

New research conducted at Rockefeller’s Laboratory of Molecular Immunology in New York suggests a natural infection may induce maturation of antibodies with broader activity than that conferred by an [mRNA] vaccination. While vaccination produces greater amounts of circulating antibodies than natural infection, the overall antibody response, or memory B cells, birthed from a natural infection […]

Antibodies produced in response to COVID-19 may trigger blood clots

July 29, 2021

A study of the antibodies naturally produced to fight SARS-CoV-2’s spike protein was found to differ from the antibodies of healthy individuals, according to researchers at the University of Reading (Reading), UK. It may also be triggering an exaggerated platelet response, which could lead to fatal blood clots in patients with severe disease. Platelets are […]

Pregnant women pass along protective COVID antibodies to their babies

March 8, 2021

New research has found that the protective antibodies pregnant women make against COVID-19 are often passed on to their foetuses – conveying natural immunity, amongst other benefits. Researchers at Weill Cornell Medicine also suggest that vaccinating mothers-to-be may also have benefits for their newborns. According to Dr. Yawei Jenny Yang, an assistant professor of pathology […]

Cancer drug delivery made more potent with microbubbles

January 12, 2021

University of Leeds research has shown how microbubbles deliver powerful cancer drugs can be guided to the site of a tumor using antibodies. Microbubbles are small manufactured spheres half the size of a red blood cell and scientists believe they can be used to transport drugs to highly specific locations within the body.   Lead researchers from the  School of Medicine, describe how they targeted […]

Some COVID-19 patients have high levels of deadly clot-causing antibodies

November 4, 2020

An autoimmune antibody circulating through the blood is attacking healthy cells and has been found to cause microscopic blood clots in people hospitalised with COVID-19, according to scientists at Michigan Medicine Frankel Cardiovascular Center (Michigan Medicine), US. In COVID-19, clots may restrict blood flow in the lungs, impair oxygen exchange, and ultimately cause life-threatening complications […]
