When the ebola thing kicked off during husseins residency, the survivors of that disease who developed antibodies were incredibly valuable as their blood could be used to fast-track immunity(ideally) and in general help with raising survival rates of other people who were infected subsequently.

In principle, this should work with all disease I assume.. and if thats the basis behind stuff like regeneron and other types of antibody treatments, it will likely help. Don't know how it ranks up to IVM/HCQ/VitC+d+zinc and the rest of those types of treatments though but I assume it complements them.
