Anthrax I am not worried about. Smallpox is another matter. I have the vaccination from years ago, and I have had boosters inthe service, but that was years ago.
I have another worry that is much more serious than any of these, and I am keeping that to myself.
That smallpox vaccination is good for 20 years. They stopped giving it in the 70's because the disease was thought to be eradicated. Many people today have not had this vaccination and even of those who have it may have been more than 20 years ago.
