Summary

In letters published this week by Science and Nature, 22 flu scientists make a case for launching potentially risky gain-of-function experiments involving the H7N9 avian influenza virus. In 2011, such experiments—which involve giving a virus characteristics it does not yet have in nature, such as the ability to infect new species—sparked a global controversy over research involving the H5N1 bird flu virus. Critics say the risks posed by the studies outweigh benefits and that proponents are overstating their value.
