I don’t think you parsed the paper quite accurately. It was just the same virus as the 50s. There was no gain of function. The mention of gain of function regards debated policy issues in 2015 when the paper was published.
- fastaguy88 6y agoThe paper says that the 1977 H1N1 is not identical to the 1950's strains, but very similar, and that a tree build from sequences suggests the 1977 strain is most closely related to the 1950's strains. So there are differences, and the question is, are they natural or synthetic. I do not think the technology was available to make synthetic changes.
