Scientists have discovered a new antibody that can effectively target the MERS-CoV virus, which causes Middle East Respiratory Syndrome. The breakthrough comes after researchers used a technique called "directed evolution" to improve the antibody's ability to bind to the virus, making it more effective at neutralizing it. This is significant because the current antibodies available for COVID-19 are not as broad in their protection, meaning they don't work against all variants of the virus. By developing this new antibody, researchers hope to create a more effective tool for fighting future pandemics and protecting people from different strains of the MERS-CoV virus.
