If the WHO's smallpox vaccination
campaign triggered an AIDS epidemic in Africa, how did so many people get
infected with HIV in the first place?
Hilary Koprowski, who is about to be featured heavily in this story,
wrote a letter to the Congressional Health and Safety Subcommittee in 1961
saying:
As monkey kidney culture is host to
innumerable simian viruses, the number found varying in relation to the amount
of work expended to find them, the problem presented to the manufacturer is
considerable, if not insuperable. As our technical methods improve we may find
fewer and fewer lots of vaccine which can be called free from simian virus.
According to
Ronald Desrosier, a professor
at Harvard Medical School, growing polio vaccine in monkey kidneys is “a
ticking time bomb.”
Desrosier acknowledges that you can
test monkeys before using their tissue and screen out those carrying harmful
viruses. But he warns that you can test only for those viruses you know
about—and that our knowledge is limited to perhaps “2% of existing monkey
viruses.”
During the 1950s-70s, virus detection
techniques were crude and unreliable. It wasn't until
the 1980s that more sophisticated testing
procedures were developed.
That was when researchers
discovered that about 50% of all African green monkeys—the primate of choice
for making polio vaccines—were infected with simian
immunodeficieny virus (SIV), a
virus closely related to human immunodeficieny virus (HIV), the infectious
agent thought to precede AIDS.

From the last study: “We hypothesize
that the AIDS pandemic may have originated with a contaminated polio vaccine
that was administered to inhabitants of Equatorial Africa from 1957 to 1959.”
This has caused some researchers to wonder if HIV may simply be SIV “residing in and adapting to a
human host.” This led others to wonder if SIV mutated into HIV once introduced
into the human population by way of contaminated polio vaccines.

Vaccine authorities were so
concerned about the possibility that SIV was a precursor to HIV, and that polio
vaccines were the means of transmission from monkey to human, that the World
Health Organization convened two meetings of experts in 1985 to explore the
data and consider their options. After all, SIV was very similar to HIV and occurred naturally in the monkey
species predominantly used by vaccine
manufacturers.
However, WHO concluded the vaccines
were safe enough and insisted the mass vaccination campaigns continue. By 1989,
they recommended not making the polio vaccine using monkeys infected with SIV.
The following year, wild
chimpanzees in Africa were found to be infected with a strain of SIV that was almost identical to HIV. Some researchers even referred to it as the “missing link” to the origins
of HIV.
Since chimpanzees were used to test
viruses for potential use in vaccines, and were kept in captivity by research
laboratories, they could have been a source of vaccine contamination.
Scientific concerns were also
heightened when researchers found some West Africans who were infected with an
SIV-like virus that was a fundamental twin to HIV. They called it HIV-2, and
like the initial HIV subtype, it was
implicated in the development of AIDS.
According to Robert Gallo: “The monkey virus is the human virus. There are monkey
viruses as close to isolates of HIV-2 as HIV-2 isolates are to each others.”
By 1991, as the result of
improvements in virus-detection techniques, researchers
found SIV DNA in the kidneys of infected
monkeys. Minced monkey kidneys were, and still are, used to produce the live polio
vaccine.
SIV was also found in the cancer
cells of an AIDS victim, and in other people as well. To many researchers, this
trail of evidence had become too persuasive to deny. Apparently, millions of
people were infected with monkey viruses capable of causing
AIDS, and this cross-species transfer
very likely occurred by way of SIV-contaminated polio vaccines.

Since most historians agree that
AIDS originated in Africa, how could it be linked to the polio vaccine if Salk
and Sabin's trials were conducted in the U.S., the Soviet Union and Eastern
Europe?
In March 1951, several years before
Drs. Jonas Salk and Albert Sabin would scuffle over whose vaccine was the true
prophylactic, Dr. Hilary Koprowski announced at a medical conference that he had become the
first doctor in history to test polio
vaccine on humans. His
“volunteers” included several institutionalized children with mental handicaps.
They drank the vaccine in chocolate milk.
From 1957 to 1960, after years of
tinkering with monkey kidneys and polio germs, Koprowski tested his own
experimental polio vaccine on 325,000 equatorial Africans, including 75,000
citizens of Leopoldville, Belgian Congo (now Kinshasa, Zaire).
Called by drums, rural natives traveled to local villages where they had
a liquid vaccines squirted into their mouths. 98% of the vaccine recipients
were infants and toddlers. The youngest children received 15 times the adult dosage. Though Koprowski
claimed he had the backing of the World Health Organization, WHO denied sanctioning the large-scale trials.
In 1959, Albert Sabin published a
study that claimed that Koprowski's polio
vaccine used in the African trials contained un “unidentified” and “unstable”
cell-killing virus. Although he was quick to point out the flaws in the vaccine
of Koprowski, his professional rival, unfortunately his ability to detect
viruses in the polio vaccine fell short when it came to mass contamination of
Sabin's own polio vaccine with SV-40.
In response to Sabin's claims of
contamination, Koprowski simply scoffed at him and said he was just trying to
discredit his work (as he would do again and again to anyone making this
accusation). The virus allegedly detected by Sabin was never identified.
Until recently, the earliest known blood sample containing antibodies against HIV was traced back to
1959. The serum came from a patient visiting a clinic in Leopoldville, one of
the epicenters of the AIDS epidemic that would occur a decade later.
Gerald Myers, a genetic sequencing
expert with Los Alamos National Laboratories in New Mexico, tracked the evolution of HIV and confirmed that today's major subtypes of the AIDS
virus in humans appear to have arisen as recently as 1960.
Although this time period is widely accepted by medical researchers, more recent conflicting reports suggest that the first HIV infection may have occurred
years earlier.
Regardless of when the first
HIV infection occurred, it would seem to be premature to dismiss the OPV (Oral Polio
Vaccine) AIDS hypothesis on this basis
alone. The timing of the first HIV infection is irrelevant to the question of
whether or not some doses of the experimental polio vaccine used in Africa in
the late 1950s were contaminated, thus precipitating a future outbreak.
Koprowski's vaccine was not
approved for human use, so it was discontinued in 1960 following the African
trials. Thus, it was only administered to inhabitants of the Belgian Congo,
Rwanda and Burundi—the precise area where high levels of HIV infection were identified by researcher 30 years later.
Furthermore, the AIDS virus is
known to infect mucous cells, prevalent in the mouth. The African vaccines were
squirted into people's mouths.
Could squirting an HIV-contaminated
polio vaccine into people's mouths cause AIDS? According to Tom
Folks, chief retrovirologist at the CDC,
“Any time a person has a lesion in his mouth, then there could be transmission”
of the virus.
Dr. Robert Bohannon of Baylor
College of Medicine asserts that squiring polio vaccines into one's mouth would
tend to aerosolize some of the liquid. Small drops could then go into the
lungs, and from there to the blood cells susceptible to infection. This could be an efficient mode of HIV transmission.
Experts believe that the average
time between HIV infection and the development of AIDS is approximately 8-10
years.
If the African polio vaccine was
indeed contaminated with SIV/HIV, initial outbreaks of AIDS would have occurred
from the mid-1960s to early 1970s. This period accurately
coincides with the emergence of AIDS in
equatorial Africa.
Understandably, authorities are
very reluctant to admit that there's even a possibility that scientists may
have contributed to the AIDS pandemic by growing polio vaccines in virus-laden
monkey kidneys.
Although dismissed by most experts,
“a few scientists, notably the biologist W.D. Hamilton, thought the hypothesis required serious investigation,
but they received little support from the scientific community.”
William Haseltine, a professor at
Harvard, believes that hypothesizing about the origin of AIDS is distracting
and nonproductive, saying, “It's not relevant...I'm not interested in
discussing it.” Dr. David Heymann, head of the WHO's Global Program of AIDS,
stated that “the origin of the AIDS virus is of no importance to science
today.”
Jonas Salk wouldn't comment on the
possibility, as apparently he was too busy working on an AIDS vaccine, and
Sabin's response was “you can't hang Koprowski with that.” Koprowski himself
initially dismissed the idea with a laugh, and then later said that “this is a
highly theoretical situation.”
His amusement must not have lasted
long, because Koprowski sued Curtis and Rolling Stone for “...the
destruction of (his) professional and personal reputation, for mental and
emotional suffering, and for...humiliation and embarrassment.” As a result the magazine was
ordered to pay $1 in damages. [See The Seeds
of Doom by Christian Biasco]
However, both Tom Folks of the CDC
and Robert Gallo thought testing the seed stocks of polio might be a good idea.
According to Folks, “any time we can learn more about the natural history [of
AIDS], it helps us understand the pathogenesis and...the transmission.”
Gallo believes that questions like
this “are of more than academic interest because answering them may help avoid
future zoonitic catastrophes—that is, transmission of disease from lower
animals to humans.”
Responding to these concerns, some
AIDS researchers formally requested samples of the original polio vaccine seed
stocks. But the government would neither release nor test them because there
are “only a small number of vials” of the material, and tests “might use it all
up.”
Inspired by Curtis' investigative
report, a British writer named Edward Hooper traveled in Africa, Europe, and the United States for
seven years. As a result of his research, he published a book in 1999 called The River: A
Journey to the Source of HIV and AIDS.
Although the scientific community
generally rejects the OPV AIDS hypothesis, Hooper “criticizes the research and
conduct of many of the scientists involved in the investigation and alleges a
'very substantial cover-up' took place to silence the hypothesis.”
One of the several arguments
against the hypothesis was that Koprowski was not using chimpanzees in his
experiments, and therefore HIV contamination didn't occur. However, eyewitness
testimony suggests otherwise.
In 2004, The Origins of AIDS, a French TV documentary strongly supportive of the OPV
hypothesis, appeared on several television stations around the world.
The film offers a convincing case for the hypothesis, and
seriously challenges the questionable nature of the categorical denials by
Koprowski and others that no chimpanzees were used in the development of his
experimental vaccine.
The Koprowski vaccines were tested
and found not to contain SIV or HIV genetic material: http://aidscience.org/Science/Cohen289(5486)1850.html
