To Aussie,
No, I’m not!
To Ames,
No to both, but I’m in the medical field. Also, any doctor can post any comment he wants on my posts and I’ll discuss it with him. Anybody can post here, as long as you register with YWN. You aren’t your doctor’s spokesman.
As far as your last question- it’s possible, but there’s no guarantee. It depends on what the antigenic shift is. So let everyone expose themselves just in case. The CDC calls this “flu parties” and they recommend against this because even this flu has caused fatalities in people. They say since we don’t know who will die from this flu (even though it’s a small percentage), even young people without other illnesses should not expose themselves on purpose.
