Summary
a new study that supercharges influenza viruses used to make vaccines a moratorium questions the US government on such research. Yoshihiro Kawaoka, a virologist at the University of Wisconsin, Madison, who is at the center of a long-standing controversy about the research called "gain of function", conducted experiments that were completed before the moratorium began in October 2014. Kawaoka supports the work emphasizes that the ban, which includes both a "financing pause" and demand that investigators voluntarily suspend work related casts too broad and hinders the search for low-risk who may benefit from public health. in this study, Kawaoka's team showed how to streamline the production of vaccines against influenza, which could be critical during a pandemic and also help seasonal vaccine manufacturers. Basically, the flu virus used to make vaccines have a backbone of six genes that remain the same each year and support two surface proteins of genes that are constantly changing. Kawaoka and his colleagues designed a skeleton that produces higher yields of surface proteins in both cell culture systems and eggs of mammals. The US government is currently reviewing research and gain of function plans to keep the moratorium in place at least until spring 06.
