Then a serum was made from their blood. Serums to fight with diphtheria and tetanus were developed this way.

Feed it to humans :D B is correct, because for making serums, one has to give disease & if that animal lives through diseases then serum can be created. For that horse/animal must have immunity in first place ! 1 1 replyShare Please log in or register to add a comment.
