Current vaccines and monoclonal antibody therapies may be insufficient to bring the pandemic fully under control because they target only one, highly mutable part of the COVID-19 virus, according to researchers at Vanderbilt University Medical Center and Washington University School of Medicine in St. Louis, Missouri.
Treatment and prevention may be more effective if multiple antigenic sites on the virus are targeted, they concluded in a paper published last week in the journal Cell.
“Our team found a new site of vulnerability on the virus spike protein that can be targeted by protective human antibodies. This gives new insights into how our vaccines are working,” said James Crowe Jr., MD, director of the Vanderbilt Vaccine Center.
Crowe, who is Ann Scott Carell Professor in the Departments of Pediatrics and Pathology, Microbiology and Immunology at VUMC, is the paper’s co-corresponding author with Washington University’s Larissa Thackray, PhD, and Michael Diamond, MD, PhD.
