Is There a Vaccine for Smallpox?

There's still high degrees of infectiousness with this ever-evolving virus. It has evolved to such an extent now and it's continuing to evolve That it's very difficult to say there's a vaccine for this virus. We don't know the full safety implication like I said, I don't want to get too far out of my skis on that. However, yeah, we know the efficaciousness of it has been a failure For what it doesn't last long Unless you're going to get reducing six times a year which I don't think anybody here would do.
