See http://liveherpesvaccine.com/category/herpes-immunology/ http://liveherpesvaccine.com/category/herpes-immunology/ for a long-running detailed blog by a different scientist who has been working on similar ideas for years. He has shown that a mutated HSV virus which is not capable of causing clinical disease (but which does cause a lifelong infection by the "harmless" version) protects against the dangerous version. This new research seems to be in the same vein:
> When introduced to a mouse, HSV-2 was able to use the HSV-1 gD to enter the mouse’s cells. Once inside, HSV-2 replicated abundantly, but because it could not produce gD, future progeny were unable to infect new cells. According to Herold, infected cells then became “little factories for making viral proteins” that spurred the immune system to produce antibodies to HSV-2.
That sounds like some cells are infected with the mutated virus and this remains as a lifelong infection. So far there seems little hope that the FDA would approve such an approach, based on Halford's experience. (See linked blog.)
- ianlevesque 12y agoI thought this was how the modern measles vaccine also functions though?
- dzdt 12y agoYou made me curious, so I did some reading. As far as I understand, the measles does use a live attenuated virus, but the resulting infection is not (normally) persistent. However, the varicella vaccine (chickenpox) DOES use a live attenuated virus that causes persistent infection.
