With the success of the vaccine, is smallpox still a bioterrorism threat? Find out how the great public health triumph of the 70s may have left us vulnerable today.

Before the discovery of the small pox vaccine, small pox was in fact used as a weapon.

One of the best documented examples of this occurred during the French and Indian War. The British had been defeated in their attempt to conquer Fort Carillon on Lake Champlain, so Sir Jeffrey Amhurst, commander of the British forces, met with Indians who were sympathetic to the French. Under the pretense of friendship, he deliberately offered them blankets previously used by small pox victims. The Indians, who lacked immunity to small pox, suffered a devastating outbreak of the disease.

The English were then able to successfully attack the Fort, which by the way, was renamed Fort Ticonderoga. Military forces have also been devastated by endemic small pox.

During the siege of Quebec, George Washington’s troops suffered massive losses from small pox.

He subsequently required all new recruits to be inoculated against the virus.

I’d like to comment for a few minutes on the Soviet program and their development of small pox, variola major. They first worked with small pox in embryonic chicken eggs, and since a very small amount of material is produced in the egg, you can imagine the large numbers of eggs that were required to produce 100 metric tons of dried agents. Now as their program advanced, and starting in the early 90s, they were using tissue culture as a means of generating the virus. But 100 metric tons loaded into an ICBM aimed at our major cities is cause for worry.

It’s incredibly ironic that the great public health triumph of eradicating small pox in the 1970s and the discontinuation of worldwide vaccination have

opened the door for this virus to be once again used as a weapon.
