Yes, we know how to breed animals and plants. But do we know how to breed flu viruses? Animals and plants are outbred, and provide great genetic diversity for selecting desired traits. But these viruses were virtually identical (no diversity), and it is completely unclear how one would "select" for a virus with the desired properties.
- burfog 6y agoWe created the live polio vaccine by breeding. That was long before fancy genetic technology. Flu viruses are particularly easy to breed. Viruses have short generation times and easy vulnerability to genetic damage. Flu viruses even have a genome that isn't in one chunk, sort of like having chromosomes, making them extra easy to breed. Selection is a simple matter of having it reproduce quickly in the desired cells.
