yes but it's kind of like a template. viruses tend not to randomly mutate, you can find the mutations very quickly after you have a small bank of virus genomes in the lab and know where to look in their genetic sequence.

the nasal spray looks promising. it's an empty virus so the body recognises it as foreign and learns to produce antibodies to it but it doesn't contain anything that aggravates the intestines and cause the symptoms. i'm hoping we can get that one out asap!!!
