LONDON (AP) — Polio, a dreaded paralyzing disease stamped out in the industrialized world, is spreading in Nigeria despite efforts to stamp it out. And health officials say in some cases, it’s caused by the vaccine used to fight it.

In July, the World Health Organization issued a warning that this vaccine-spread virus might extend beyond Africa. So far, 124 Nigerian children have been paralyzed this year — about twice those afflicted in 2008.

The polio problem is just the latest challenge to global health authorities trying to convince wary citizens that vaccines can save them from dreaded disease. For years, myths have abounded about vaccines — that they were the Western world’s plan to sterilize Africans or give them AIDS. The sad polio reality fuels misguided fears and underscores the challenges authorities face using a flawed vaccine.

Nigeria and most other poor nations use an oral polio vaccine because it’s cheaper, easier, and protects entire communities.

FDA Allows Use of Experimental Antiviral Drug to Treat H1N1

Friday, November 27th, 2009

The U.S. Food and Drug Administration is allowing the use of an experimental antiviral drug to treat severe cases of H1N1 or swine flu.

The drug, Peramivir, is currently being developed by BioCryst Pharmaceuticals Inc. and is undergoing testing required for regular FDA approval.

The FDA issued a so-called emergency use authorization late Friday that allows doctors to use Peramivir, which is delivered intravenously, in certain hospitalized adult and pediatric patients with confirmed or suspected H1N1 influenza.

A handful of doctors have already treated patients with severe cases of H1N1 using Peramivir obtained through the agency’s expanded access rules that allow individual patients to obtain experimental drugs if certain conditions are met. The emergency-use authorization allows use of the drug without prior FDA approval.

Potato Vaccine for Hepatitis B: Syringes off the Menu?

Scientists have shown that, for hepetitis B vaccine, genetically modified potatoes may be an alternative to the syringe and needle.

The hepatitis B virus (HBV) causes liver failure and liver cancer. Despite the availability of a safe, injectable vaccine, the virus currently infects an estimated 350 million people worldwide and kills about a million people every year.

In recent years scientists have raced to develop oral vaccines with genetically modified plants as a means to overcome the economic and safety limitations of syringe-and-needle vaccination programs, especially in developing countries.

“The whole concept of oral vaccines, versus injections, is a very attractive one. As you can imagine, we are used to taking things by mouth. They are easy, and there are not associated problems with potential contamination due to syringes and needles,” said Yasmin Thanavala, an immunologist at the Roswell Park Cancer Institute in Buffalo, New York.

Previously researchers have shown that potatoes can deliver vaccines for intestinal pathogens such as the E. coli and Norwalk viruses, which enter the body via the mouth.

This week in the research journal Proceedings of the National Academy of Sciences, Thanavala and colleagues report on the first human, or clinical, trial for a plant-derived HBV vaccine. HBV is transmitted by blood or sexual fluids.

Ex-DAFB commander says troops used as guinea pigs

Thursday, October 1st, 2009

Military denies that illness of pilots, crew caused by squalene.

A former Dover Air Force Base commander says military officials used his troops as guinea pigs in illegal medical experiments under the government’s controversial anthrax vaccination program.

After some of his troops in their 20s and 30s began developing arthritis, neurological problems, memory loss and incapacitating migraine headaches, Col. Felix Grieder took a drastic step. In 1999, he halted the vaccination program in Dover, a move he said ended his military career. The decorated Air Force colonel has spent the past five years trying to discover the truth about the vaccine program in Dover, where he commanded 4,000 troops.

“In my opinion, there was illegal medical experimentation going on,” says Grieder, who lives in Texas.

Grieder has interviewed scores of his former pilots and crew who say they have had life-altering reactions to the vaccine.

“They would have no reason to lie. I believed them,” he recalls. “I wanted to talk to them face to face.”

Dover is now ground zero in the controversy because troops there were injected with anthrax vaccine containing squalene, a fat-like substance that occurs naturally in the body. Squalene boosts a vaccine’s effect, but some scientists say injecting even trace amounts of it into the body can cause serious illness.

Government officials have acknowledged that the Department of Defense secretly tested squalene on human beings in Thailand. Grieder believes they did the same in Dover.

In a March 1999 report, the General Accounting Office accused the Defense Department of a “pattern of deception” and said the military confirmed human tests involving squalene only after investigators found out about them.

The Department of Defense says vaccine sent to Dover was accidentally contaminated with squalene. Grieder and other officers believe, however, that it was intentionally introduced to test pilots and crew in Dover.

The Defense Department made anthrax inoculations mandatory for all active-duty military personnel in 1998. The immunization order, which remains in effect today, calls for six shots over an 18-month period. Defense officials deny that military personnel were illegally used as guinea pigs to test a vaccine containing squalene.
