Bill Gates Describes How 'Catalytic Philanthropy' Can Help Bring Vaccines, Medicines To Untouched Markets

In an essay adapted for Forbes magazine from a speech given at the Forbes 400 Summit on Philanthropy in June, Bill Gates, co-chair of the Bill & Melinda Gates Foundation, discusses how “[i]nnovations for the poor suffer from … market limitations” and his idea of “catalytic philanthropy.” Gates writes, “The market is not going to place huge bets on research when there are no buyers for a breakthrough. This explains why we have no vaccine for malaria today, even though a million people die from it every year.” Therefore, “when you come to the end of the innovations that business and government are willing to invest in, you still find a vast, unexplored space of innovation where the returns can be fantastic,” he continues.

Dengue Vaccine Initiative Launches Redesigned Website, New Blog

The Global Network for Neglected Tropical Diseases’ “End the Neglect” blog reports that the Dengue Vaccine Initiative has launched a redesigned website, including a new blog that “will include regular posts about the disease, dengue in the news, the work of DVI and the development of a dengue vaccine” (9/17).

VOA News Report Examines PEPFAR's Use Of Generic Drugs, Discusses Search For HIV Vaccine

In a recent edition of VOA News’ “Science In The News,” correspondents Bob Doughty and Shirley Griffith report on “the growing use of generic drugs in fighting HIV” and discuss “the search for an effective vaccine against HIV.” They highlight a study of the effectiveness of PEPFAR conducted by researchers from Brown University in Rhode Island, noting lead researcher Kartik Venkatesh “says the high cost of patented antiretroviral drugs had an immediate influence on the program after it began.” They continue, “American officials considered whether to provide patented drugs to HIV-infected patients, both in the United States and overseas,” adding, “Using generic drugs helped cut the cost of treating a person [in a developing country] from about $1,100 a year to about $300 a year in 2005.”

Hereditary Blood Disorder Found In South-East Asia, South-West Pacific Could Offer Clues For Malaria Vaccine

“A team of international scientists has found that a type of hereditary disorder in some communities in South-East Asia and the South-West Pacific protects its sufferers from malaria, a finding that could drive future vaccine design,” SciDev.Net reports. “Southeast Asian Ovalocytosis (SAO), an inherited disorder in which red blood cells are oval, instead of round, could be a unique human adaptation to resist malaria, according to a paper published in PLoS Medicine this month,” the news service writes.

U.N. SG Warns Withdraw Of Aid Groups From Haiti Leaves Country Struggling With Cholera Epidemic

U.N. Secretary-General Ban Ki-moon “warned on Friday that Haiti was struggling to cope with a cholera epidemic that has killed thousands and deteriorating conditions in tent camps as aid groups withdraw from the impoverished country due to a lack of funding,” Reuters reports. “In a report to the U.N. Security Council, Ban said there had been an increase in the number of cholera cases since the rainy season began in early March and the World Health Organization had projected there could be up to 112,000 cases during 2012,” the news service writes.

VOA Examines Global Polio Eradication Efforts

VOA News reports on global efforts to eradicate polio, writing, “Experts say with India now polio-free and the total number of cases at the lowest level ever, this is an opportunity to change history and eradicate the disease entirely.” “The oral polio vaccine has cut the number of polio cases worldwide by 99 percent since 1988,” but, “[f]or the past 10 years, … eliminating that last percent has remained a challenge,” the news service continues. “The three countries where polio is still endemic — Nigeria, Pakistan, and Afghanistan — are conducting aggressive immunization campaigns to vaccinate more children against the disease,” VOA notes.

Some Guinean Residents Seek Cholera Vaccine; Outbreak In Sierra Leone Winding Down

With nearly 6,000 reported cholera cases, including more than 100 deaths, Guinea is facing the worst cholera outbreak since 2007, and “some residents of the capital Conakry are clamoring to be vaccinated,” IRIN reports. “The cholera vaccine has shown promising results in the handful of communities where it has been used: none of those vaccinated have been infected,” the news service writes, noting, “For now cholera vaccination is not generally done on a large scale.” According to IRIN, “WHO and partner agencies are planning a cholera vaccine stockpile for epidemic control and looking at the possibility of introducing the two-dose oral vaccine into national immunization programs in endemic areas,” but the agency also “says such stockpiles should not detract from other prevention efforts: detection, diagnosis, and treatment of cases with oral rehydration and antibiotics; establishment of a safe water supply; implementation of adequate waste disposal, sanitation, and hygiene; and communication and social mobilization.”

WHO Says Nigeria Not On Track To Turn Back Polio Despite Having Tools, Capacity

“The World Health Organization (WHO) on Tuesday said Nigeria was not on track in the effort to eradicate wild polio virus before the end of December this year,” Leadership/AllAfrica.com reports. Speaking at the 24th Expert Review Committee (ERC) Meeting on Polio Eradication in Abuja, Bruce Aylward, WHO assistant director-general for polio, emergencies and country collaboration, said Nigeria had the tools and capacity to turn back the increasing number of polio cases that pose a “real and growing danger to international public health,” the news service notes. Aylward “recommended eight major steps for polio eradication for the country, including the implementation of the new house-based micro planning and monitoring method,” refresher training for all personnel to emphasize the emergency status declared by the WHO, and the identification and immunization of missed children and those in insecure areas, among others, according to the news service. ERC Chair Tomori Oyewale “called on Nigerians to change their attitude to polio eradication to ensure the success of the fight against the virus,” the news service writes (9/11).

Cholera Vaccine Stockpiles Could Help Save Lives In Future Outbreaks

In a post in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, Helen Matzger, a program officer in new vaccine delivery at the foundation, writes about outbreaks of cholera in Haiti, Sierra Leone, Guinea, and other areas, and says creating stockpiles of a recently WHO-approved cholera vaccine could help save lives in the future. “The creation of a cholera stockpile is not a panacea; … Still, the cholera vaccine works. Though many of us may never need it, millions of people living in some of the poorest regions of the world face cholera outbreaks all too often. We have a way to alter the course of an outbreak and save lives. Let’s use it,” she concludes (9/19).

Clinical Trial Results Signal 'Promise, Unresolved Challenges' In Finding Effective Dengue Vaccine

The first-ever results from a dengue virus vaccine clinical trial aimed at showing effectiveness “provide signals rather than definitive answers, and a mixture of both promise and unresolved challenges,” Orin Levine, executive director of the International Vaccine Access Center, and Ciro de Quadros, executive vice president of the Sabin Vaccine Institute, write in the Huffington Post “Impact” blog. “To date, these represent the most promising indications that a safe, effective vaccine to prevent dengue is technically feasible,” they continue, adding, “At the same time, the results on protection were inconclusive, somewhat inconsistent with the measured immune responses and uneven across the four strains included in the vaccine.”
