The Reemergent 1977 H1N1 Strain and the Gain-of-Function Debate (2015)
The article notes that a lab leak or gain of function research or both are suspected because research with cultivated influenza strains was common at that time.  In contrast, attempts by researchers at Wuhan to consistently cultivate coronavirus were unsuccessful.  That is why they decided to work with chimeras instead of pursuing gain of function research.<p>All of this focus on the point of origin is misplaced.  We know that there will be new viruses.  What matters is how we respond to them.  In this case the US response was completely botched.  This is in part because the team that had been in place to deal with emerging virus threats was disbanded and also in part because the CDC was forced to focus on making the president look good instead of dealing with the virus.  What is ultimately being argued here is that instead of being prepared and responding reasonably all we have to do is control research and nothing like this will happen.  Unfortunately, this is obviously false.
