The new trick is that they are able to discover the structure of molecule they need through computer simulations modeling immune system/virus. Basically it uses Recombinant DNA technology to mass produce this. It's already being used to produce growth hormone of various kids for use in humans, swines and bovines. Difference here is that tho, in growth hormone we know the structure of peptide already as it can be extracted from the pituitary of the cadaver
