>Is there, and was there in the 1980's, a vaccine that is more prevalent in the american male gay realms than the gen pop?

 

Hepatitis B Vaccine Experiment On American Gays

 

In the name of God America trust, the US government clandestinely carried out experiments on human beings with impunity

In the period from 1978 till 1981, the Centers for Disease Control conducted a hepatitis B vaccine experiment on homosexuals living in New York City, San Francisco, and Los Angeles.

 

HIV/AIDS was first detected among the participants in the CDC hepatitis B vaccine trial and quickly spread throughout the gay community in those cities. A body of evidence, including a detailed statistical analysis of the documented timeline of when HIV infection was detected in the men’s blood and reported to the CDC.

 

Dissidents who have studied the available published data are convinced that this ill-conceived experiment precipitated the devastating AIDS epidemic in America’s homosexual community.

 

The gay men in the experiment were injected with a vaccine that had been made using human hepatitis B infected blood which was injected into chimpanzees known to be infected with the cancer-causing simian virus 40 (SV40); the virus that had contaminated the polio vaccine.

 

Before these CDC experiments, there were no reported cases of HIV or AIDS in America. The AIDS epidemic was officially declared by CDC in 1981, at the conclusion of the experiment.

 

Yet, in the New England Journal of Medicine published report researchers proclaimed the vaccine “safe and incidence of side effects low,” and claimed a 96% success rate.

 

They failed to mention the emergence of a new disease affecting some of the subjects.

 

The men in the 'Manhattan experiment' had the highest rate of HIV ever recorded for that time period: 20% were discovered to be HIV-positive in 1980, and over 40% in 1984.

 

In addition, a re-examination of the stored blood samples from an AIDS trial in NYC by epidemiologists at the National Cancer Institute found that one out of five gay men (20%) tested positive for the new KS herpes-8 virus (Kaposi’s Sarcoma virus in 1982.)

 

Before 1978, no stored blood anywhere in the US tested positive for either HIV or the Kaposi’s Sarcoma virus, which was not identified until the mid-nineties.

 

An extraordinary PBS taped an interview with medical historian Edward Shorter and Dr. Maurice Hilleman, Merck’s foremost vaccine developer acknowledged that the polio vaccine, manufactured by Merck, had been contaminated with SV40.

 

He also indicated the likelihood that SV40 is the source of AIDS: “I didn’t know we were importing AIDS.”

 

Hilleman nevertheless defended the contaminated vaccine stating: “it was good science at the time because that was what you did. You didn’t worry about these wild viruses…” But in fact, the taped interview was never aired for fear of liability, but it was submitted to the Library of Congress and in 2011 posted on YouTube.

 

.

In fact, two main questions remain;

How did these two viruses of primate origin get into the gay male population to cause AIDS and a contagious form of cancer?

 

Can the AIDS epidemic in the US be traced directly to this CDC’s experiment?

 

Given the lethal nature of these two combined viruses, it is likely that many, if not most, of the men in the CDC experiment eventually died of AIDS.

 

The actual number of AIDS deaths among the men in the experiment has never been revealed, nor have their medical records were studied. Efforts to obtain this information have been rebuffed invoking the “confidential” nature of the experiment to deny access.

The Advisory Board of The Dutch Government

The reason Johan van Dongen, the Dutch scientist and micro-surgeon, read over 30.000 scientific papers, books and everything else he needs for revealing the truth about the real origin of Aids and Ebola was in line with the findings of the above-mentioned experiment.

 

Together with many more evidence, this was the turning point for him in his carrier as the probe by the establishments themselves. For him this evidence came to light on June 13th, 1978, when he attended the meeting; ‘DNA-Research in Discussion in Utrecht The Netherlands.'

 

During the meeting of The Royal Dutch Academy Of Sciences, the Advisory Board of The Dutch Government, he met Bart Kempinga who was at that time biology student at the University of Groningen, where his doctoral research was at the Department of Science and society sub-faculty of biology with the subject: “Social developments relating to the processing of genes.”

 

He was also a member of the High School, working on a combination of the cancer virus SV40 with a common intestinal bacterium Escherichia coli in our intestines.

 

Discussing the dangers of these horrific experiments with him his very short answer was; “It is breaking good science and simply the investigation of the moment. It is just what we do nowadays….”

 

In fact, you didn’t worry about wild viruses is my overall conclusion…?!!

 

But facts history from genetic engineering research particularly in the United States wherein 1978, already exists more than two hundred institutions with recombinant DNA techniques work without proper guidelines. Even so, the Russian Academy of Sciences had a considerable number of recombination in its name.

 

Professor Dr. H.H. Cohen

Professor Cohen, a physician, and bacteriologist was one of the panelists the speakers questioned about the figure and the safe safety aspects over the recombination of human E-coli bacteria with SV40 DNA tests.

 

Cohen is also the director of the National Institute for Public Health RIV and on behalf of the Dutch Government responsible for the manufacture of dangerous vaccines.

 

Cohen, who dealt with very dangerous vaccines, stated at the above-mentioned meeting; “I can assure you, we know the vaccines are very dangerous but we just try to make it harmless! It is known that in the preparation of such vaccines certain components are included before being released."

 

He further stressed, "Let me give you an example: It isn’t secret that live polio vaccine is also in inactivated polio vaccine, the two forms leukemia, which you currently learned on television, mid-seventies of the last century, that contains a possible tumor virus consist namely, the Simian Vacuolating Virus SV40."

 

"Those tumor viruses, which causes AIDS eds., oncogenic and tumorigenic were later traced in polio vaccine and also on an international level within the framework of the WTO, which established requirements that vaccines should meet."

 

"The wonder is that this international community from many countries in East and West are generally becoming consensus since this issue began to emerge. Partly socially enforced was because they knew that each other’s preparations would recover."

 

Editorial

With regards to eugenics, particularly the influence of human behavior is a number of developments in the last century. In fact, with recombinant DNA technology, the establishments have played a role in the war and human depopulation experiments and projects.

 

This means the principle of parliamentary democracy is incompatible with the state of affairs, where scientists behind closed doors determine how our society will be like, especially since scientists are aware, but mostly unconsciously, quite easily in the service of small but powerful interest groups. We all know the examples.

 

Scientists also require more and more what our future will look like because the business by allowing it to our scientific and technological progress continues to keep busy reaching consequences for the nature of our society content.

 

However, it is quite an extremely worrying development when scientists in public will complain about their need to politicians who don't understand nothing and mess up everything.

 

But what about Africa the continent of guinea pigs? There were a variety of wide experiments by dubious scientists and a crook like Hillary Koprowski. During the most normal course of business, he heavily genetically engineered with SV40 contaminated vaccines on innocent and ignorant Africans.

We know in many books and tens of thousands of scientific papers about AIDS and depopulation projects that are developed under the Apartheid regime and in the former Belgian Congo.

 

Nowadays almost nobody knows how disastrous the first steps in the vaccination era have been because Koch’s vaccine caused Tuberculosis T.B.C. As a consequence of these inoculations, thousands of children and adults died, because of Koch’s contaminated vaccine.

 

Kochs' statement; “Because of this contamination no man on earth is free of viruses and other micro-organisms and when people get sick then we’re working against it now and in the future by making a drug in animals.”

 

This is precisely the beginning of the end of it as it turns out by the emerging of Ebola and Aids. These first vaccinations by famous pioneers were the beginning of inserting or administrating animal micro-organisms into the human immunological system.

 

Exchanging of micro-organisms which will change the lives of millions of Africans, because they are victims of unbridled experiments of the ruthless military, pharmaceutical and medical establishments and especially Hillary Koprowski.

MAP OF AIDS' DEADLY MARCH EVOLVES FROM HEPATITIS STUDY

 

https://www.washingtonpost.com/archive/politics/1987/02/01/map-of-aids-deadly-march-evolves-from-hepatitis-study/47cd206c-c8d9-4082-896f-a075e53bd221/

 

SAN FRANCISCO – In the late 1970s, thousands of homosexual and bisexual men came to San Francisco's public venereal diseases clinic to participate in a government-sponsored study of hepatitis B.

 

As they gave blood for the project, they had no way of knowing that a time bomb was ticking on a then-unknown disease far more threatening than anyone could have imagined and that the signs of the future epidemic AIDS lay hidden in the vials they filled.

 

By 1987, health authorities had learned at least 600 of the 6,700 participants had acquired immune deficiency syndrome. About 375 of them were dead from it. And a sample survey taken shows that about 70 percent of the participants tested positive for the AIDS antibody – indicating that they likely were carrying the virus.

 

For them, and for all of those involved in the study, the figures are tragic testimony to the speed and virulence of the epidemic some experts predict could become the worst in modern history.

 

But their participation in the study has brought at least one priceless benefit: The stored frozen blood has offered an unexpected opportunity to track the path of the AIDS virus over time in a large vulnerable group, teaching researchers more about the progress of the disease than any other single study. It is, as well, a harbinger of what can happen when the AIDS virus goes unchecked.

 

The study which evolved into one focusing on AIDS is showing, among other things, that the incubation period is much longer than many had earlier suspected; that the chance of becoming sick increases with time among those infected, with the likelihood of getting AIDS greater in the second five years after infection than the first.

 

The study has been more than science. The history of this research project is the history of AIDS itself. It has been a very human study, staffed largely by gay men who have themselves been touched by the devastating disease they are studying.

 

"It was a potential gold mine of information," said Paul M. O'Malley, who has coordinated the study for the San Francisco Department of Public Health and the federal Centers for Disease Control (CDC) since its start in 1978. O'Malley has since watched nearly 20 of his friends come down with AIDS and come to know dozens more with AIDS in the study.

 

Both professionally and personally, "we're in the front lines," he said.

 

"It is the longest follow-up study of any group of people in the United States or anywhere in the world for AIDS," said CDC official Dr. Harold W. Jaffe. "The study was done primarily because of the cooperation of the gay community, mainly by gay men. They are doing the study as scientists, but the findings are affecting them personally."

 

"It provided us with a picture window of what happened in a population before AIDS was known to exist and what has happened since then," added CDC researcher Dr. William W. Darrow. "I think that the value of the study and all research is in convincing other people of the real emergency of the situation."

 

A decade ago, San Francisco was a magnet for gay men, who came from all parts of the country, from all walks of life to explore their sexuality in a city where they were more accepted. Even then there were health consequences gonorrhea, syphilis and other ailments that led everyone from businessmen to bartenders to seek confidential medical help at the public clinic.

 

O'Malley, then a communicable disease investigator for the city, was concerned that the sexual revolution could breed more serious health problems for gay men "in the fast lane," but certainly nothing as deadly as AIDS.

"Looking back on that time, I used to think something was going to happen sooner or later. I worried about a resistant strain of gonorrhea or syphilis. I didn't think of some new virus that could decimate the community when people are in the prime of their life," recalled O'Malley, a gay man who had come from Massachusetts after a stint as a public health inspector in the Air Force.

 

In 1981, the hepatitis study produced a major victory: a hepatitis vaccine tested on the San Francisco group and in several other cities worked. But there was little chance to celebrate, as health officials began to worry about something far more ominous than hepatitis.

 

At a May 1981 meeting in San Diego, O'Malley heard of a mysterious new illness, one which had caused homosexual men in California and New York to die of rare forms of pneumonia and cancer. Something was apparently attacking their immune systems. A few weeks later the first five cases were cautiously announced to the world in the CDC's Morbidity and Mortality Report.

 

O'Malley got involved when a man in the hepatitis study called and said he had come down with Kaposi's sarcoma, a skin cancer associated with what would come to be known as AIDS. His interest intensified when many of the first AIDS cases in San Francisco 11 of the first 24 in 1981 turned out to be participants in the hepatitis project.

 

Many of the hepatitis participants had filled out elaborate questionnaires about their lives, from sexual habits to drug use. In 1983, CDC and the city health department agreed to contact a sample of the participants and question them again to see if they could isolate special risk factors for AIDS.

 

By the spring of 1984, researchers at the Pasteur Institute in France and the National Cancer Institute had isolated the cause of AIDS, a new virus that knocked out key immune system cells. And CDC began using an experimental blood test to look for antibodies to the virus.

 

Using the test and samples of the frozen blood, the researchers tracked the footprints of the AIDS epidemic in the San Francisco men. They found that:Undetected, the virus had spread rapidly among this group of sexually active men. With the consent of the participants, CDC randomly tested stored blood samples and found about 3 percent of the gay men in the hepatitis study showed antibodies to the then-unknown AIDS virus in 1978, rising quickly to 12 percent in 1979, 20 percent in 1980 and 36 percent in 1981. By 1983, 62 percent were positive.

 

Although the rise has since slowed, preliminary results show that more than 70 percent of those tested in 1986 follow-up studies were positive on the AIDS antibody blood test. A positive antibody blood test generally signals long-term infection. Many people initially hoped that a positive AIDS antibody blood test meant past exposure to the AIDS virus but did not have serious long-term consequences. But CDC studies using data from the San Francisco project have since found that the virus can in fact be found in the blood of most of those who are positive. Because many people in the hepatitis vaccine study gave frequent blood samples, instances in which a person converted from negative to positive can often be pinpointed within months. For every case of AIDS, there are far more people who may be infected with the virus but show no symptoms. The government's oft-quoted projections that more than 1.5 million Americans may already be infected with the virus, in addition to over 29,000 reported AIDS cases nationally, is based in part on what has happened to these San Francisco men. In San Francisco, the gap is closing faster. In a selected sample of 66 infected men followed for an average of about six years, one-fourth have already developed AIDS and more than one-third have developed symptoms of illness that sometimes precedes AIDS. Only 25 men 38 percent remain free of symptoms, said Nancy Hessol, a statistical expert with the San Francisco study. There are exceptions. Four people who have been antibody-positive for at least nine years based on stored blood samples from January 1978 still have not come down with AIDS, O'Malley said.

But most findings have been disturbing. "I hoped my worst fears would not come true. At first the data showed that the vast majority of people won't get sick. I held on to that for a long time. Now there is a very different picture," he added.

 

Dubbed "Father O'Malley" by a colleague who admires his protective concern for study participants, he said he is not infected with the AIDS virus but admits that "sometimes men like myself have feelings of survivor guilt. How come I slipped through?"

 

The AIDS project is reached through an unmarked door on Market Street, where a security guard keeps out vagrants. In the fourth-floor suite of offices overlooking city hall even the telephone operator answers with the street address and not the name. But once inside the confidential sanctuary, a giant red flag with bold white letters announces that it is the "S.F. City Clinic AIDS Research Study."

 

The flag is more than symbolic. O'Malley and many of the small staff of 10 or so carried the banner last June in the annual lesbian and gay rights parade in San Francisco, a parade filled with protest over an AIDS ballot initiative pushed by followers of political extremist Lyndon H. LaRouche Jr. The initiative soundly defeated in the November elections raised fears in the gay community about possible discriminatory actions.

 

CDC and San Francisco health department officials credit O'Malley and his mostly gay staff with doing a remarkable job while juggling their roles as researchers, city employes and members of a community so dramatically affected by the epidemic.

 

"I don't think we made a conscious decision to use gay men as the investigators," said CDC's Jaffe. But "it may make the study participants more comfortable in participating. They may not trust the federal government. They may not trust the city government. But they do trust Paul and his staff. It means a lot of credibility."

 

Every participant in the study is guaranteed confidentiality. Perhaps the most sensitive aspect of the study has been its use of the blood test that measures the presence of antibodies to the AIDS virus. Participants are offered the opportunity to learn the results of their blood tests or to choose not to, with all findings in the research statistics anonymous.

 

Doug Franks, now a 34-year-old research associate for the San Francisco AIDS study, has been exposed to and presumably infected with the AIDS virus.

 

He said that in the late 1970s he had numerous sexual relationships with men and women, including a 1978 affair with San Francisco Supervisor Harvey Milk shortly before he was slain by a political foe. In 1979, Franks came to the city clinic for a checkup and became a participant in the hepatitis B study. In 1984, Franks heard of the new AIDS study and volunteered to be tested again.

 

Last year, he was hired by the health department and asked to work on the AIDS project, conducting interviews with study volunteers. He also decided to learn his own AIDS test results.

>>18101693

Tests of his stored blood showed that when he entered the hepatitis study in 1979 he was negative for antibody to the AIDS virus, but by the time he was retested in 1984 he was positive.

 

He feels fatigued at times and has shown signs of swollen lymph nodes. "When you see the statistics this study generates, it's not hard to project what's going to happen. It's going to be a pretty bumpy ride . . . . The possibility of coming down with AIDS in the future seems very real."

 

For Franks, the decision to learn his blood results was "a benefit . . . . Knowing your own antibody status can motivate you to make the necessary changes in your life style, to reduce the risk of coming down with AIDS as well as protect others from infection." He was able to inform former sex partners so they too could be tested and now has a live-in lover. And the knowledge that he is positive makes him more eager to consider "aggressive action" as new AIDS virus therapies come along.

 

Concern about the impact of telling men in the study that they had been infected with a potentially deadly virus led staff member Michael A. Frigo to do a follow-up study on the psychiatric reactions. At the Second International Conference on AIDS in Paris last June, Frigo reported that in a sample of 800 men, about half of those tested elected to find out the test results – of them about two-thirds were indeed positive for infection.

 

Each was provided with counseling. Although there were no reports of suicide attempts or psychiatric hospitalization, Frigo reported "significant negative psychological impact," with "increased fear, anger and possible depression one month after receipt of results."

 

Long-term follow-up continues. But within two weeks of returning from Paris, Frigo was struck by a sudden illness and died of AIDS in a San Francisco hospital.

 

Meanwhile, the numbers of AIDS victims from among the San Francisco project's 6,700 volunteers account for about 20 percent of San Francisco's AIDS cases and one out of 50 cases in the United States.

 

"So far its a pretty scary picture," says Torsten Weld Bodecker, 31, who updates the AIDS project's confidential computer data base. "Periodically what hits me when I print a list of code numbers with date of birth and date of death is to see, page after page, they are my age, they are my friends, they are people who I have interviewed . . . . I don't see those numbers decreasing; I see those numbers increasing."

 

Every day he must discreetly contact men to ask them to rejoin the study, to come in and undergo a complete physical as well as an extensive, hour-long interview that goes into the most intimate details of their lives the kind and amount of sex they have, whether they use drugs, whether they drink as well as memory tests to check their recall.

 

"The bottom line is that a lot of people are dying. I tell them they have an opportunity to do something about that . . . . I don't try to harass them," he said. The fact that he is gay "helps break the ice. They know I'm not going to be judgmental and that I have the same kinds of concerns they have."

>>18101695

Bodecker too faces a very personal threat. He has been antibody-positive on the AIDS blood test for nearly four years and still feels completely healthy. But just in case, he has "written a will and made it clear what I want done with my remains." He was willing to talk about himself "because this disease needs to have stigmatization taken away as much as possible. It's important to be up front."

 

While many gay men have been reluctant to join the government-sponsored AIDS study, many of those who have are enthusiastic about their participation, for personal and altruistic reasons.

 

"It's like a confessional, only it's scientific and not in a church," said London Wildwind, a 40-year-old Arkansas-born gay "psychic healer" who has been in San Francisco for two decades. "If you want self-worth and value, sometimes you have to be a volunteer. You have to be honest."

 

"It's a question of love your neighbor and help each other out. It's not a gay disease. It's a disease of the people. That's the only way we're going to lick this," said LaRon Gneiting, 37, a gay merchandise manager who came here from Blackfoot, Idaho, after a failed marriage.

 

There have been a few rays of sunshine in the gloomy news generated by the San Francisco study. Most significant, said CDC's Darrow, have been the changes in sexual behavior documented by the study.

 

He says that in 1978, the average number of different sexual partners over a four-month period among gay men in the hepatitis study was 30. When the group was reinterviewed in 1984, the number over the same time period had dropped to six. In 1985, it went down to four and in the last survey in 1986, down to two.

 

"The number who have decreased high-risk exposure, such as anal intercourse, has decreased as well," Darrow said.

 

"The vast majority of men interviewed are dealing with this epidemic in a realistic manner," O'Malley said. "In fact, in the past three years San Francisco has dropped from second to thirteenth place among the nation's cities in the incidence of gonorrhea, and the rectal gonorrhea decline has been the most dramatic of all in this disease group." A decline in VD is considered evidence that unprotected sexual activity is declining.

 

While health authorities urge the use of condoms and sex that does not involve the exchange of bodily fluids to reduce the spread of AIDS, "monogamy and celibacy have been the alternative for a growing number of gay males," O'Malley said.

 

Over the last three years, about 2,000 men who participated in the original hepatitis study have been contacted and 1,200 of them have been included in the new AIDS study. Now the San Francisco AIDS project is starting an expanded nationwide effort to find the remaining 4,700 men who participated in the original study and confidentially ask for their help in hopes of finding more clues about why some people get AIDS and others don't.

 

Negotiations are under way with a drug company to offer some men in the study a chance to participate in a new study of the anti-AIDS drug AZT and its effect on those who have been infected with the AIDS virus but shown no symptoms of illness. Those who have received the highly publicized drug thus far have largely been AIDS patients.

 

The San Francisco researchers are sensitive to the need to offer the AIDS study participants whatever help should become available, rather than simply follow the men over time.

 

"We don't want to be accused of being the Tuskegee of AIDS," said Dr. George W. Rutherford, medical director of the San Francisco health department's AIDS office. The Tuskegee Institute study was a controversial federally funded study of untreated syphilis, begun in 1932, in which the effects of the disease in black men in rural Tuskegee, Ala., were followed for 40 years, even after penicillin treatment became available.

 

Added O'Malley: "We want to do something for these men, rather than just write them off."

History

Hepatitis B Vaccine History

The hepatitis B vaccine is the first anti-cancer vaccine because it can help prevent liver cancer. Worldwide, chronic hepatitis B and C causes 80% of all liver cancer, which is the second most common cause of cancer death. Therefore, a vaccine that protects against a hepatitis B infection can also help prevent liver cancer.

 

History of the Vaccine

 

The hepatitis B virus was discovered in 1965 by Dr. Baruch Blumberg who won the Nobel Prize for his discovery. Originally, the virus was called the "Australia Antigen" because it was named for an Australian aborigine's blood sample that reacted with an antibody in the serum of an American hemophilia patient.

 

Working with Dr. Blumberg, microbiologist Irving Millman helped to develop a blood test for the hepatitis B virus. Blood banks began using the test in 1971 to screen blood donations and the risk of hepatitis B infections from a blood transfusion decreased by 25 percent. Four years after discovering the hepatitis B virus, Drs. Blumberg and Millman developed the first hepatitis B vaccine, which was initially a heat-treated form of the virus.

 

First Commercial Hepatitis B Vaccine

 

In 1981, the FDA approved a more sophisticated plasma-derived hepatitis B vaccine for human use. This “inactivated” type of vaccine involved the collection of blood from hepatitis B virus-infected (HBsAg-positive) donors. The pooled blood was subjected to multiple steps to inactive the viral particles that included formaldehyde and heat treatment (or “pasteurization”). Merck Pharmaceuticals manufactured this plasma vaccine as "Heptavax," which was the first commercial hepatitis B virus vaccine. The use of this vaccine was discontinued in 1990 and it is no longer available in the U.S.

 

Current Recombinant Hepatitis B Vaccines

 

In 1986, research resulted in a second generation of genetically engineered (or DNA recombinant) hepatitis B vaccines. These new approved vaccines are synthetically prepared and do not contain blood products - it is impossible to get hepatitis B from the new recombinant vaccines that are currently approved in the United States.
