This is still in early an phase of development, but it's an interesting approach:
>>>Using computational tools, a team of researchers at the University of Washington designed and built from scratch a molecule that, when pitted against the coronavirus in the lab, can attack and sequester it at least as well as an antibody does. When spritzed up the noses of mice and hamsters, it also appears to protect animals from becoming seriously sick.
This molecule, called a mini-binder for its ability to glom onto the coronavirus, is petite and stable enough to be shipped en masse in a freeze-dried state. Bacteria can also be engineered to churn out these mini-binders, potentially making them not only effective but also cheap and convenient.<<<
With help from computer algorithms, researchers designed proteins from scratch that can trounce the coronavirus in lab animals.
