And consider, potential parents are looking to optimize their embryo via things like CRISPR. This changes genes in a somewhat uncontrolled way. So the wind is blowing towards genetic mutation and trust is going to be required.
Small scale, if they found an invariant region of influenza viruses, can produce it and it passes testing, sign me up. This will really knock flu occurrence back until they mutate around it. Which hopefully will take a while. Think of the reward if they can do this to knock back aids so people don’t need to take drug cocktails their whole life.
