In antibody therapy, blood is taken from a person who has already survived COVID-19 from which antibody-producing B cells are extracted and used in sequencing technology to make new and more antibodies. If we can work out the type of antibody that neutralizes SARS-CoV2 in the laboratory, we can then produce massive quantities of the antibody that can be injected into patients experiencing COVID-19, helping them fight the infection.
The trial conducted by Regeneron Pharmaceuticals tests a mixture of two monoclonal antibodies, which both attach to the spike of the virus at slightly different places. To make sure the virus mutates and the structure changes, at least one should work, as many scientists have feared a major mutation that would cause all vaccine trials to fail for good.
Vaccines on the other hand provide “active immunity” and can be made up of either a piece of the virus, an inactivated virus or an active virus that no longer has the ability to cause disease. Once the vaccine is injected into the body, the immune system launches an attack as if the person actually has COVID-19.
