Reject genetic engineering of smallpox, NGOs urge WHO
A campaign has been launched to request the World Health Organization
(WHO) not to proceed with a project involving the genetic engineering
of the smallpox virus and instead to ensure that all remaining stocks
virus are destroyed within two years.
A proposal to the WHO to allow
the genetic modification of small pox virus was first initiated by the
United States at a WHO technical advisory committee, which recommended
its acceptance to the WHO's executive board. The proposal will come before
the World Health Assembly (WHA) in May.
"The proposal to genetically engineer smallpox, which would also
genes to be inserted into related poxviruses and the unlimited distribution
segments of smallpox DNA, poses a large number of public health, biosafety,
biological weapons risks," warned Edward Hammond, Director of the
US office of

According to the NGOs' briefing paper, while the WHO is justly proud of
effort that brought about the eradication of smallpox in 1977, the truth
is that the job
was never finished. The US and Russia still retain stocks of the

Smallpox kills one quarter or more of the people it infects and leaves
many who do
not die disfigured and blind. The virus is thought to have killed around
people in the 20th Century alone. In the 1960s, it still killed more than
people every year.
Smallpox was defeated by a WHO-led public health surveillance and targeted
vaccination programme that began in 1967. The final natural outbreak occurred

said that in 1999, the remaining stocks of smallpox virus were slated
destruction on 30th June. But Russia and the US balked at the WHA resolution
calling for them to destroy their stocks of the virus.
Under pressure, the WHA then agreed to a time-limited "temporary
retention" of live
smallpox, rescheduling destruction for 2002. However, in May 2002, the
yielded on the smallpox destruction deadline by agreeing to an indefinite
of the destruction order, until the US and Russia completed research including
development of new anti-viral drugs, a new vaccine, sequencing more strains
smallpox, and developing a monkey model of human smallpox infection, said
NGO briefing paper.
In the meantime, the US has accelerated smallpox research and now wants
the Pandora's Box of genetically-engineered smallpox, said the NGOs. In
2001, the US first proposed to genetically engineer smallpox and to insert
genes in other poxviruses.
And in January 2005, the WHO Executive Board agreed to forward recommendations
that would permit the US experiments, to the WHA. However, because of

November 2004, the WHO Director General also announced that he would conduct
a study of the issue.
Little is known about this study. However, said the briefing paper,

be tabled prior to the World Health Assembly in May 2005, when a decision
If the proposal is implemented, the NGOs foresee that it would pose serious
risks and could moreover open the road to an artificial reconstruction
of the virus for
biowarfare purposes. They also fear that the WHO now seems to have lost
political will that it once had to finish the job of smallpox eradication.
According to Hammond, much of the blame can be laid at the doors of the
decision to leave oversight of smallpox research in the hands of an imbalanced
highly politicized "technical" advisory committee known as the
Committee (VAC). Set up in 1999, the VAC is dominated by a small number
countries and scientists with a personal interest in pursuing smallpox
pressure eventually pushed the proposal for genetically-engineered smallpox
that committee, he said.
At a December 2001 meeting of the VAC, the first discussion of the US
genetically engineer smallpox took place. It concluded that a detailed

The NGOs want the WHA to reject the proposal. "The creation
of genetically-engineered smallpox and hybrids of smallpox and other viruses
(called chimera) pose serious public health, biosafety, and biological
weapons dangers to the entire world," Hammond said.
According to the NGOs, the proposal raises two serious biosafety issues:
accidental escape of the smallpox virus during experimental lab work,
potential construction of dangerous new viruses through genetic engineering.
The NGOs fear that with increased smallpox experimentation, the world

release of the virus.
As many poxviruses are closely-related to each other and, in their natural
frequently not entirely species-specific, the insertion of smallpox genes
viruses has the potential to create dangerous new human (and animal) pathogens.
Through genetic engineering or targeted mutations, laboratories that receive
of the smallpox genome may develop the ability to create smallpox or a

Moreover, as Hammond points out, "laboratory safety practices and
cannot erase human error and equipment failures". These can lead
to accidents, as
evidenced by a recent string of lab-acquired infections and environmental
SARS, Ebola, tularemia, and other dangerous diseases. In fact, the last
human cases of smallpox were laboratory-acquired.
The NGOs fear that if the proposal is endorsed by the WHA, the intergovernmental
encouragement of the creation of genetically-engineered disease agents
will come at
a particularly dangerous time.
Globally, the number of high containment facilities handling dangerous
is expanding and the hazardous applications of biotechnology are increasing.

recent years involving highly pathogenic agents in high containment facilities.
According to Hammond, the scope and quantity of research on biological
agents are growing, particularly in the US, and now exceeds the cost of

The NGOs are urging the member states of the WHO to reject the committee's
recommendations and instead:
* Prohibit the genetic engineering of smallpox, the insertion of smallpox
other poxviruses, and any further distribution of smallpox genetic material
* Set a firm and irrevocable date, within two years, for the destruction
