OK, to be honest, I DIDN'T plan on discussing music here - so that was an entirely reasonable question Alex (my brother is a musician - does that count?!) Anyway, thanks for allowing me to post.
Hi Newberry; I can't say definitively why smallpox dissapeared. The vaccine could have played a role but I think it is impossible to say just how much. It could be attributed to the natural decline of the disease as more and more people developed natural immunity. Do you think this is possible? Apparently only 10% of the population was ever vaccinated against smallpox (I'll try and find a reference later) so the fact it has dissapeared must not be completely due to the vaccine.
From what I understand in Australia (and I have been trying to find some information on the govt website) the disease had largely gone before the vaccine arrived here. They (health officials) are not attributing the dissapearance to the vax, anyway, from all I have read so far.
Smallpox may have declined/dissapeared of its own accord in the same fashion as the bubonic plague, scarlet fever, cholera, the Black death, yellow fever - and possibly others I'm not aware of. I don't know if the vaccine helped or hindered in this - some say that the innoculation especially kept the disease alive longer than necessary as it was so problematic. I am not dismissing the vaccine as having nothing to do with the decline - though I am questioning whether it is taking alot more credit than it deserves.
I don't claim to have all the answers - I am still learning! But when I read simplified statements of how we were saved from smallpox due to vaccination - I am suspicious. I have read enough to question this assumption. Common sense also tells me the disease would have waned on its own with improved sanitation. I think there is an association with bedbugs?
I'd be interested to hear what you think of some of this stuff, though -

I will also have a look at the CDC website later, but for now must get back to my girls!
