coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.COVID-19 antibodies last at least three monthsPeople infected with COVID-19 develop antibodies targeting the new coronavirus that last for at least three months, according to two reports published on Thursday in Science Immunology.
The two studies, together involving nearly 750 patients, both point to immunoglobulin G (IgG) antibodies, which start showing up well after an infection begins, as the longest-lasting.
Researchers found IgG antibodies with two targets - a spike protein on the virus that helps it infect cells, and a part of the spike called the receptor binding domain (RBD) - lasted more than 100 days.
