The reason it's not researched much is because giving someone an antibody will not confer immunity - it will only treat the immediate virus.

It has value, but there are usually better treatments available that more broadly fight a variety of viruses and don't need to be so specifically customized as an antibody.

I suppose testing would be easier for a cure (compared to a vaccine)? Given that only the "adapter" needs to be specialized, I was wondering why there don't seem to be any approaches based on antibody mass-production....
