"Agreed. I don't think anyone's ethnicity or heredity will protect them from SARS. Sad to say."

Actually, anyone who gets SARS and survives is such a person. Inheriting an efficient immune system is as much a genetic trait as any other factor (wish I had one--I catch every virus that comes near me--if I'm ever exposed to SARS, I suspect I will be "pushing up privet hedge").

Yes, and those rare resistant people who are not vulnerable to the virus will come from any and all ethnic groups, imho.

Sorry but the virus is mutating to such a degree that if you get it once and survive, you can get it again... and maybe not survive. I am not aware of any such immunity in relation to sars... may be out there but I haven't read it. Plus if you do survive SARS your lungs are so scarred that they become very ineffective, from what I read.
