A coronavirus vaccine is still months away, but an antibody treatment could be closer

Scientists can create what are called monoclonal antibodies: lab-made antibodies created specifically to target an infection. Vaccines have the advantage of working longer than an antibody treatment. Antibody therapies potentially last a month or two and then wear off, but they can be used to temporarily protect vulnerable populations such as nursing home residents or healthcare workers or people with chronic conditions. The therapies could also treat people who are already sick with Covid-19. CNNHealth
