“Vaccine for All? Math model supports mass smallpox inoculation” failed to mention an important complication for any type of smallpox-inoculation program: The vaccine might not work. A smallpox outbreak could be caused by a viral strain purposely engineered to evade any commercially available vaccine. Also, how likely is it that a new smallpox vaccine would produce the same successful result in me that I got when I was vaccinated as a child? How about side effects from a modern vaccination? I need more information about the science of smallpox inoculation before I’ll willingly submit to a booster-immunization strategy.
