The TWiV team reviews identification of immune biomarkers in CFS/ME patients, and how a cell nuclease controls the innate immune response to vaccinia virus infection.

Vincent visits the Rocky Mountain Laboratories in Hamilton, Montana and speaks with Marshall, Sonja, and Byron about their work on tick-born flaviviruses, innate immunity, and prion diseases.

This episode of TWiV was recorded before an audience at the Beth Israel Deaconess Medical Center, where Vincent and Alan spoke with Dan and Jeff about AIDS vaccines.
