With the world eagerly awaiting a vaccine for COVID-19, scientists are also busy researching antibodies.
Research is ramping up to produce targeted antibodies that could provide an instant immunity boost against the virus.
Called"monoclonal antibodies", they could both prevent and treat the disease.
Clinical trials are already underway and could produce signs of efficacy in the next few months.
If successful these antibodies could potentially save lives and change the way the world fights COVID-19.
There have been over 18 million cases of COVID-19 reported worldwide.
