Agreed. I actually met a guy a week ago that's working on monkey pox- the next big pox threat. He told me that it's a growing problem and more people are getting infected by it in Africa- larger than what would be explained by the fact that people have stopped vaccinating for small pox. It suggests that monkey pox is an "up and coming" virus. So there's active research on pox, and it's silly to simple throw it away.
The probability of the CDC's stock escaping is really very small, and let's face it, if we got rid of it once we could get rid of it again.
