That's the 64 million dollar question BP. No one really knows. It has been proven that after 20 years, vaccinated folks still will only measure 4%
lethal, as opposed to 50% of those unvaccinated. So I'm assuming I still have some residual resistance to it. It used to be thought that it was
life-long immunity, but that was disproven, I believe in 1798.
Someone did a study once a long time ago, about milkmaids in Europe who didn't get smallpox. It was discovered that the milkmaids would scratch the
cow, put their fingers in it and lick it - basically they were immunizing themselves against smallpox, because they were exposed to cowpox, a similar
virus. Since they were immunized against cowpox from the cow, they were also immunized against smallpox.
Something to remember, if smallpox erupts and there are no vaccinations available.
