Unless I'm mistaken, being born in 1963, I received smallpox vaccinations as a child. Does the efficacy (sp?) change over time, and are boosters necessary throughout life? In other words, is my vaccination good any more?
My understanding is that they stopped vaccinating because the virus had been more-or-less eradicated in the wild--although there have been some isolated cases in other countries in the last several years. When did they stop administering the smallpox vaccine?
