Title: Newly Discovered Antibodies Show Promise in Fighting All Covid Variants
Subtitle: Groundbreaking research unveils potent antibodies capable of neutralizing multiple strains of the virus

In a significant breakthrough, a team of international scientists, led by Duke-NUS Medical School in Singapore, has identified six new antibodies that could potentially combat every strain of Covid. These groundbreaking findings come as the global community continues to grapple with the highly transmissible Omicron variant, which has caused a surge in Covid cases worldwide.
The most powerful antibody discovered, known as E7, has demonstrated the ability to neutralize newly emerged SARS-CoV-2 variants, including the Omicron XBB.1.16 variant responsible for a significant increase in Covid cases in the United States. E7 works by blocking the shape-shifting process that the virus undergoes in order to infect cells and cause illness.
Researchers have found that E7 binds to two coronavirus spike proteins simultaneously, rendering them useless and preventing the virus from invading host cells. This new antibody has shown promising results in the lab, effectively neutralizing the latest variants, including Omicron.
Despite a recent increase in Covid cases and hospitalizations in the US, experts from the Centers for Disease Control and Prevention (CDC) emphasize that the current wave remains significantly lower than previous waves. Dr. Brendan R. Jackson, the CDC’s Covid-19 incident manager, stated that these early signs do not require immediate concern. Additionally, Covid-related deaths continue to decline steadily.
The development of these monoclonal antibodies offers hope for more effective treatments against Covid and other related viruses. Previous attempts to utilize mass-produced monoclonal antibody treatments had limited success due to the rapidly evolving nature of the virus. However, the newly discovered antibodies were found in the immune systems of patients who had previously recovered from the original SARS and received the Pfizer-BioNTech mRNA vaccine against Covid-19. This combination resulted in a more potent mix of natural and vaccine-guided immunity capable of consistently attacking various sarbecoviruses.
The research team consisting of scientists from Singapore, Australia, and the United States discovered that these monoclonal antibodies also showed efficacy against other coronaviruses transmitted between mammals, such as bats and pangolins. The antibodies demonstrated an ability to neutralize a wide range of Sarbecoviruses, not just those unique to Covid.
The study’s senior author, Wang Linfa, expressed optimism about the potential for pan-coronavirus vaccines based on these findings. If the human immune system can be “educated” in the right way, pan-coronavirus vaccines could become a possibility.
Further research is needed to advance the therapeutic potential of E7 and the other monoclonal antibodies identified. The collaborative effort between Duke-NUS Medical School, National University of Singapore, University of Melbourne, and Fred Hutchinson Cancer Research Center aims to explore the development of these antibodies as therapeutic treatments against current and future strains of coronavirus.
As the world continues to battle the ever-evolving Covid landscape, the discovery of these potent antibodies provides a glimmer of hope in the fight against the virus. With further research and development, scientists may be one step closer to developing effective treatments that can combat all strains of Covid and potentially future sarbecoviruses.
