The largest TWiV panel ever assembled takes on XMRV and chronic fatigue syndrome, 2009 chemistry Nobel prizes for ribosome structure, finding new poxvirus vaccine candidates, a brouhaha over leaked Canadian data on influenza susceptibility, and transmission of H1N1 influenza to a pet ferret.

Vincent and Dick discuss influenza virus-like particle vaccines produced in insect and plant cells, rapid sharing of influenza research, and answer listener questions about cytomegalovirus, viral evolution and symbiosis and much more.
