Drugmakers, health groups bring HPV vaccine to girls in poor countries

Two multinational drugmakers are teaming up with top global health groups to protect millions of girls in the world's poorest countries from deadly cervical cancer.

Starting with pilot programs in eight Asian and African nations, the ambitious project ultimately is intended to inoculate more than 30 million girls in more than 40 countries by 2020. Given that most women killed by cervical cancer live in developing countries, the project could have a huge impact.

The endeavor was announced Thursday by the GAVI Alliance, a public-private partnership that's worked with drugmakers to deliver affordable vaccines to poor countries to treat childhood illnesses that are big killers.

"This is a transformational moment for the health of women and girls across the world," said Dr. Seth Berkley, CEO of GAVI, which is short for Global Alliance for Vaccines and Immunization.

"A vast gap currently exists between girls in rich and poor countries. With GAVI's programs we can begin to bridge that gap so that all girls can be protected against cervical cancer no matter where they are born," he said in a statement.

Drugmakers Merck & Co. and GlaxoSmithKline PLC initially will provide 2.4 million doses of their vaccines against cancer-causing human papilloma virus - for a fraction of the cost commanded in Western countries.

Merck will supply its Gardasil for $4.50 per dose, and Glaxo its Cervarix for $4.60 per dose. In the U.S., the shots cost well over $100 apiece, and a three-dose series over six months is required.

The vaccines protect against the strains of human papilloma virus, or HPV, that most commonly cause cancer. The virus, transmitted during sex, causes cervical cancer as well as vaginal, vulvar, anal and oral cancers. The vaccines prevent roughly 70 percent of those cancers.

In developed countries, older girls and women routinely get Pap tests to check for cervical cancer or signs of precancerous changes in cervical tissue. They're treated promptly, often before cancer begins, and few die. And increasingly, young girls and now boys as well are vaccinated with either Gardisil or Cervarix, starting as young as age 9 so they're protected well before they become sexually active.

Not so in poor countries.

"They don't have the benefit of screening to catch cancer early, when it can still be treated," Dr. Julie L. Gerberding, president of Merck Vaccines, said in an interview.

As a result, 85 percent of the 275,000 women killed by cervical cancer each year live in poor countries, where HPV is most prevalent.

"It is a disease that has devastating, life-threatening consequences and it is preventable," said Gerberding, an infectious diseases expert who's a former director of the Centers for Disease Control and Prevention. "Our aim is to do what we can to make the vaccine available."

The GAVI project will begin "demonstration projects" administering the vaccines to girls aged 9 to 13, starting in Kenya as early as this month. Then it will be expanded to Ghana, Laos, Madagascar, Malawi, Niger, Sierra Leone and Tanzania.

The goal is for the governments of those countries to show they can set up a national system - with medical staff, clinic supplies, distribution systems and supply management all well organized - to provide the vaccines over the long term. The program also will bring an opportunity to teach the girls about nutrition, sexual health and HIV prevention.

Already, GAVI is planning to provide the shots nationwide in Rwanda, starting next year.

Merck, based in Whitehouse Station, N.J., is providing 93 percent of the shots initially. It's also agreed to provide more shots at an even-lower price in the future, if higher volumes of vaccines are ordered, as that would reduce production costs.

Merck and Britain's GlaxoSmithKline are among the world's biggest makers of vaccines, and both have long provided many for free or at discounted prices to health programs in poor countries.

GAVI also will work with the heavy hitters of global health and development groups, including the CDC, the World Health Organization, UNICEF, the Bill & Melinda Gates Foundation and the World Bank. Other partners include the charities, corporations and 18 wealthy countries that help fund GAVI.

In the U.S., the vaccines have become steady money makers since they were launched a half-dozen years ago, but they haven't turned into the mega-sellers initially envisioned.

That's partly because of their high price here, but also because of political fights. Some conservative groups opposed the vaccines, arguing that giving adolescents a vaccine to protect them against a virus transmitted by sexual activity would encourage it.

Monster Beverage says no link between caffeine and teen girl's death

Monster Beverage Corp, facing concerns over the safety of its energy drinks, said on Monday that it has found no evidence that the death of a 14-year-old girl was caused by her drinking two Monster Energy drinks.

Monster was sued last year by the family of Maryland teenager Anais Fournier, who died after suffering from cardiac arrest her family says was related to her drinking two Monster Energy drinks on consecutive days. They sued Monster for failing to warn about the alleged dangers of the drink.

Following the suit, Monster hired a group of doctors to study whether the caffeine from the drinks contributed to her death.

The company said on Monday that its doctors found "no medical, scientific or factual evidence to support the Maryland Medical Examiner's report of 'caffeine toxicity,'" said Daniel Callahan, a lawyer for Monster. He said no blood tests were ever done to test her blood's caffeine levels.

Kevin Goldberg, a lawyer for the Fourniers, told Reuters there were other symptoms of caffeine toxicity, though he declined to elaborate.

"We have our experts and they have their experts," Goldberg said, adding that it was "not appropriate ... to litigate the case in the media."

The lawsuit said Fournier died from "cardiac arrhythmia due to caffeine toxicity" that complicated an existing heart valve condition related to a disorder called Ehlers-Danlos syndrome.

Monster's doctors said the most likely cause of Fournier's death was myocarditis, inflammation of the heart muscle. They said that would not have been exacerbated by caffeine.

Energy drinks are caffeinated beverages with aggressive-sounding names like Monster, Red Bull, Rockstar, AMP and Full Throttle. They are often associated with active or extreme sports, which makes them popular with young men.

In addition to the Fournier lawsuit, the U.S. Food and Drug Administration said in October that it was investigating reports of five deaths that might have been associated with Monster's namesake drink.

Monster shares were down 97 cents, or 1.9 percent at $49.69 on the Nasdaq.
