Old smallpox vacination vs. current smallpox
I received a smallpox vacination as an infant in 1964. Does that vacination provide protection against the current smallpox virus that could be used in bio-warfare?
Information is incomplete, but it seems that immunity from smallpox vaccine starts to fade 5-10 years after vaccination. By 20 years after vaccination immunity to smallpox is probably gone.
