First you must recognize that this article was written by a loon, and published in the Sierra Times.
There is some good information in it, but it is colored by the fact that this person does not believe any vaccine works. They devote a great deal of space to claiming that none of our vaccines for any disease has been proven to work, and to claims that Vitamin C and giving up sugar are proven to protect you from Viral infection.
I agree that Smallpox is not as infectious or as lethal as the sensationalists in the press have been saying, but that doesn't make it a lesser risk than the new vacine. My guess is that this person would also recomend you not vaccinate your children against Tetanus or Polio.
The original smallpox vaccine was thought to give 4 to 10 years of immunity. Data from all our other live virus vaccines developed since then seems to indicate that the immunity may be lifelong. That would mean that the older part of the population would already be protected.
An attack by smallpox would hurt us far less than any other country on earth, because of our medical facilities. No dictator is gonna use Smallpox to attack us until his military and government have been vaccinated, and vaccinating them would be a giveaway clue that they were the attackers. A smallpox epidemic would spread worldwide, and any nation that starts it can expect to be nuked till they glow by the US, Russia, and everyone else with a bomb to spare. They would not have a single supporter anywhere.
I don't think we are in much danger of a Smallpox attack, but I will certainly get re vaccinated if the vaccine is made available, because I don't think the vaccine is dangerous and I don't think Vitamin C is gonna protect me.
