Yeah. Canada also has an AIDS vaccine too.this is what no fly zones are for.
Now is it because the bugs are tougher or there is a lack of will to invent them.
There still is no cure for male pattern baldness so I expect its less to do with profit motive.
I think we just have tougher bugs.
I never heard of a Canadian aids vaccine, if there is such a thing its never caught my eye in the news ( and I read a lot of news )
