MediGuard (which has changed its name from iGuard) may be the biggest Health 2.0 membership site of all. Launched in 2007 as a spin-off of Quintiles, where Hugo was a senior executive, iGuard now has in excess of 2 million members in the US and another 100K plus in the UK. They’re getting information about interactions and recalls, being involved in frequent studies and are also being recruited for clinical trials. Hugo is a frequent visitor to the US but has been living in Paris. He’s moving back to his native Australia very soon. Ready for Health 2.0 Australia perhaps?
