It seems to have some potential against the venom. That may at least help to minimize damage. Itīs a huge advantage that it does not need refrigerating. Thatīs going to increase availability significantly.
I am little sceptical about the claims on pricing though.
Even if the antivenom lives up to all the claims Iīd be reluctant to get bitten. It just doesnīt sound like a fun activity to me.
