No to GM Smallpox!

*****************

 

Non-governmental organizations around the world are urging

the World Health Organization to block a dangerous proposal

that would allow the smallpox virus to be genetically

engineered, and to ensure that remaining stocks of the virus

are destroyed within two years Lim Li Ching

 

The almost eradication of smallpox

 

Smallpox kills one quarter or more of the people infected

and leaves many others disfigured and blind. The virus is

thought to have killed around 300 million people in the 20th

Century alone. Into the 1960s, it still killed more than 2

million people every year.

 

Smallpox was eradicated by the WHO-led public health

surveillance and targeted vaccination programme that began

in 1967. The final natural outbreak occurred in Somalia's

Kurtunwaarey District in October 1977. However, the US and

Russia still hold onto stocks of the infectious smallpox

virus (Variola major); and this has long been a source of

contention, as the virus is also a likely biological weapon

that could be deployed in a terrorist attack.

 

Alarm was raised recently by a US-led proposal to

genetically engineer the virus, and also to allow small

segments of smallpox DNA to be freely distributed and the

smallpox genes to be inserted into related poxviruses.

 

The proposal has been recommended to the World Health

Assembly (WHA) through an imbalanced advisory committee

dominated by a small number of countries and scientists with

interest in smallpox virus research. The proposal will be

debated at the meeting of the WHA in Geneva, Switzerland,

16-25 May 2005.

 

Repeated refusal to destroy virus stocks

 

The WHA had previously called for the smallpox virus stocks

to be destroyed by 30 June 1999; but neither Russia nor the

US had complied. Under pressure, the WHA had then agreed to

a time-limited " temporary retention " of the live virus,

rescheduling destruction for the end of 2002. In May 2002,

however, the WHA again gave way on the destruction deadline

and took an even larger step backwards, agreeing to an

indefinite extension of the destruction order until the US

and Russia completed a far-ranging research agenda.

 

The US first proposed to genetically engineer smallpox in

December 2001 via a WHO advisory committee.

 

After an opaque committee process including e-mail

negotiations in January 2005, the WHO Executive Board agreed

to forward recommendations to the WHA that would permit the

US experiments.

 

But because of controversy aroused when the recommendations

were first made public in November 2004, the WHO Director

General also announced that he would conduct a study of the

issue.

 

Public health, biosafety and bioweapons risks

 

Edward Hammond, Director of the US office of The Sunshine

Project, an international watchdog on biological weapons

issues, warns that the proposal " poses a large number of

public health, biosafety, and biological weapons risks. "

 

It could open the gate to the artificial reconstruction of

the virus, and leave the world vulnerable to accidental or

deliberate releases of the virus.

 

As many poxviruses are closely-related to one another, and

in their natural state frequently not entirely species-

specific, the insertion of smallpox genes in other

poxviruses has the potential to create dangerous new

pathogens.

 

Through genetic engineering or targeted mutations,

laboratories that receive pieces of the smallpox genome may

be able to create smallpox or a novel virus with its

characteristics without ever receiving an actual sample of

Variola major.

 

Genetic engineering can cause unintended effects, and more

often than not, the results are not predictable. In such

cases, there is a potential danger of inadvertently

constructing highly lethal pathogens.

 

Lab accidents happen

 

Moreover, human error and equipment failures can lead to

accidents, as shown by a recent spate of lab-acquired

infections and environmental releases of SARS, Ebola,

tularemia, and other dangerous diseases. The last reported

cases of smallpox in humans were laboratory-acquired.

 

The recent panic over a deadly strain of pandemic flu virus

that had been accidentally sent to 3 747 labs around the

world (see Box) underlines the risk of disease from

laboratory accidents.

Killer flu virus accidentally released by US lab

 

On 12 April 2005, thousands of scientists around the world

were scrambling to destroy vials of a pandemic flu virus

inadvertently sent to 3 747 labs in 18 countries.

 

The virus that caused the 1957 Asian flu pandemic, H2N2, was

accidentally released by a lab in the US and sent all over

the world as part of a test kit. The WHO urged immediate

destruction of the samples, fearing that the samples could

spark a global flu epidemic.

 

The 1957 pandemic strain started in China before spreading

worldwide and killing between 1 and 4 million people. It is

not included in the current flu vaccines. Persons born after

1968 are expected to have little or no immunity to H2N2, as

another hybrid virus had replaced the H2 type virus by then.

So an escape of the virus in the test kits could be lethal

for them.

 

The College of American Pathologists (CAP) had sent the flu-

testing kits to the labs between October 2004 and February

2005. The CAP is a professional body that helps laboratories

to improve their accuracy by sending them samples of various

germs to identify.

 

The CAP kits were prepared by private contractor Meridian

Bioscience in Cincinnati, US, and were supposed to contain a

particular strain of influenza A, the viral family that

causes most flu worldwide. But instead of choosing a strain

from the hundreds of recently circulating influenza A

viruses, the firm chose from its stockpile the deadly 1957

H2N2 strain.

 

According to the WHO, almost 99% of the labs that received

the test kits are in the US. Fourteen are in Canada and 61

samples went to labs in 16 other countries: Bermuda;

Belgium; Brazil; Chile; France; Germany; Hong Kong; Israel;

Italy; Japan; Lebanon; Mexico; Republic of Korea; Saudi

Arabia; Singapore and Taiwan.

 

On 26 March 2005, National Microbial Laboratory Canada

detected the 1957 pandemic strain in a sample not connected

with the test kit. The lab eventually traced the virus to

the test kit. This means that the virus had already escaped

within the lab.

 

Test kits for flu are not handled at a high level of

biological containment as it is assumed they do not carry

unusually dangerous viruses. The escape in the Winnipeg lab

is worrying, as the lab contains facilities with the highest

level of containment and its staff is expected to maintain

high levels of lab hygiene. The most probable means of

escape into the outside world would be if a lab worker

catches the Asian flu, then passes it on.

 

The WHO said that no H2N2 flu outbreak has been reported

since the first batch of test kits was sent to laboratories

in October 2004. Nevertheless, the incident raises

unsettling questions about lab-handling of flu viruses and

other pathogens.

_________

 

 

If the WHA approves the recommendations, it will not only

increase the threat of smallpox through accidental or

deliberate release, it will also be setting a precedent for

other dangerous human (and animal) pathogens to be

genetically engineered.

 

An alliance of NGOs* are urging governments to reject the

recommendations and instead to: Prohibit the genetic

engineering of smallpox, the insertion of smallpox genes in

other poxviruses, and any further distribution of smallpox

genetic material for non-diagnostic purposes

 

Set a firm and irrevocable date for the destruction within

two years of all remaining stocks of smallpox virus

(including viral chimeras, or hybrids with other

poxviruses);

 

Ensure in the interim before destruction that the WHO

Advisory Committee on Variola Virus Research and its

advisors are regionally balanced and that the Committee and

its subsidiary groups conduct their oversight activities in

a fully transparent and accountable manner.

 

*The NGOs, including Third World Network and The Sunshine

Project, have set up a website, www.smallpoxbiosafety.org,

where organizations and individuals can send letters to the

WHO Director General. The website also provides links to

national health ministries, so that people can contact their

government representatives.
