Biotech x-risk is a tricky subject, since research into how to prevent it also is likely to provide more information on how to engineer biothreats. It's from nontrivial to know what lines of research will decrease the risk, and which will increase it. One doesn't want a 28 Days Later type situation, where a lab doing research into viruses ends up being the source of a pandemic.
You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
