WHA drops deadline to destroy smallpox stocks


Acting on fears of bioterrorism, the 191 World Health Organization (WHO) members on Saturday formally reversed a long-standing order for the destruction of all smallpox virus stocks and recommended they be retained for research into new vaccines or treatment.

The World Health Assembly (WHA), the U.N. health agency’s top decision-making body, decided to back an earlier recommendation by WHO Director-General Gro Harlem Brundtland to drop a 2002 deadline for destroying the virus.

Under the ruling, no new target has been set for destroying the stocks, which are held at two secure laboratories, one at the U.S. Centers for Disease Control and Prevention in Atlanta, and a similar Russian facility in Siberia. The virus stocks will be retained for research into new vaccines or treatment for smallpox and the WHA will receive updates on the research at its annual meetings.

U.S. assistant surgeon general Kenneth Bernard told the assembly that smallpox research was necessary because the “events of Sept. 11 have underscored the extent that terrorists are willing to go to.”

“In recent years, experts have come to see smallpox as a No. 1 deadly threat,” and the danger of deliberate use was “small but growing,” he said. “We regard the potential release of smallpox as a critical national security issue, not only for us but for the entire world.”

Research also would help people suffering from HIV/AIDS, whose weakened immune systems could not stand existing smallpox vaccines, he added. Please see WHA on page

The assembly said that full research results should be made available to all WHO member nations — a decision made after developing countries said they feared rich nations would keep the results to themselves, WHO officials said.

Smallpox used to kill 3 million to 4 million people per year and left millions more scarred and blind. It was declared eradicated in 1979 after a massive WHO-spearheaded campaign, and the virus samples were placed in the U.S. and Russian laboratories.

Mainland China previously had called for the destruction of the stocks, claiming their very existence presented an enormous risk to the world. But the Chinese delegation agreed to drop the deadline, provided the research was completed as soon as possible and a new date was set for destruction at a later meeting of the assembly.

Although international teams carry out regular checks of the virus storage facilities to ensure maximum security standards, there have been long-standing fears that samples may not be secure.

Russian officials, however, told the assembly that the stocks in their laboratory were completely secure and dismissed the idea that virus samples could be stolen.
