No, but I understand that it's a really interesting program. It was recommended to me that if I had not figured out what to study for post grad, they suggested that I apply to the Integrated Immunology and get a "taste" of grad life and hopefully figure out what to apply for in a Ph.D. It helps if you've had a chance to meet some Profs etc before applying for the Ph.D.
Also, the M.Sc course doesn't take that many students - so congrats on your offer!!
Can I ask how long from the time that you applied till your offer? Did you go through a phone or in person interview?
