From Ebola Researchers, An Anthem of Hope
Posted on by Dr. Francis Collins
After watching this music video, you might wonder what on earth it has to do with biomedical science, let alone Ebola research. The answer is everything.
This powerful song, entitled “One Truth,” is dedicated to all of the brave researchers, healthcare workers, and others who have put their lives on the line to save people during the recent outbreak of Ebola virus disease. What’s more, it was written and performed by seven amazing scientists—one from the United States and six from West Africa.
NIH Ebola Update: Working Toward Treatments and Vaccines

Updated Oct. 22, 2014: The National Institutes of Health (NIH) today announced the start of human clinical trials of a second Ebola vaccine candidate at the NIH Clinical Center in Bethesda, MD. In this early phase trial, researchers from NIH’s National Institute of Allergy and Infectious Diseases (NIAID) are evaluating the vaccine, called VSV-ZEBOV, for its safety and ability to generate an immune response in healthy adults who receive two intramuscular doses, called a prime-boost strategy.
The Walter Reed Army Institute of Research is simultaneously testing the vaccine candidate as a single dose at its Clinical Trials Center in Silver Spring, MD. VSV-ZEBOV, which was developed by researchers at the Public Health Agency of Canada’s National Microbiology Laboratory, has been licensed to NewLink Genetics Corp. through its wholly owned subsidiary BioProtection Systems, both based in Ames, Iowa.
Early human testing of another Ebola vaccine candidate, co-developed by NIAID and GlaxoSmithKline, began in early September at the NIH Clinical Center. Initial data on that vaccine’s safety and ability to generate an immune response are expected by the end of 2014.
We are all alarmed by the scope and scale of the human tragedy occurring in West African nations affected by the Ebola virus disease epidemic. While the cornerstones of the Ebola response remain prompt diagnosis and isolation of patients, tracing of contacts, and proper protective equipment for healthcare workers, the National Institutes of Health (NIH), led by its National Institute of Allergy and Infectious Diseases (NIAID), is spearheading efforts to develop treatments and a vaccine for Ebola as quickly as possible.
For example, NIAID has supported and collaborated with Mapp Biopharmaceutical, Inc., San Diego, in its development of the product known as ZMapp, which has been administered experimentally to several Ebola-infected patients. While it is not possible at this time to determine whether ZMapp benefited these patients, NIAID is supporting a broader effort to advance development and clinical testing of ZMapp to determine if it is safe and effective. In addition, the U.S. Biodefense Advanced Research and Development Agency (BARDA) has announced plans to optimize and accelerate the manufacturing of ZMapp, which is in limited supply, to enable clinical safety testing to proceed as soon as possible.
Eradicating Ebola: In U.S. Biomedical Research, We Trust

Updated August 28, 2014: Today, the National Institutes of Health (NIH) announced plans to begin initial human testing of an investigational vaccine to prevent Ebola virus disease. Testing of the vaccine, co-developed by NIH’s National Institute of Allergy and Infectious Diseases (NIAID) and GlaxoSmithKline, will begin next week at the NIH Clinical Center in Bethesda, MD.
As the outbreak of Ebola Virus Disease continues to spread in West Africa, now affecting four countries in the region, I am reminded how fragile life is—and how important NIH’s role is in protecting it.
NIH research has helped us understand how Ebola initially infects people and how it spreads from person to person. Preventing this spread is currently our greatest defense in fighting it. Through research, we know that the Ebola virus is transmitted through direct contact with bodily fluids and is not transmitted through the air like the flu. We also know the symptoms of Ebola and the period during which they can appear. This knowledge has informed how we manage the disease. We know that the virus can be contained and eradicated with early identification, isolation, strict infection control, and meticulous medical care.
Print-and-Fold Origami Microscope for 50 cents

When Stanford University bioengineer Manu Prakash traveled to a mosquito-infested rainforest in Thailand a couple of years ago, he visited a clinic with a sophisticated, $100,000 microscope that sat unused in a locked room. It was then Prakash realized that what global health workers really need is an ultra-low cost, simple-to-use, portable microscope that could be deployed in the field to diagnose disease—and he took it upon himself to develop one!
The result is the Foldscope, a ‘use and throwaway’ microscope that Prakash demonstrated last week at the first-ever Maker Faire at the White House. While I saw many amazing inventions and met many incredible inventors at this event, I came away particularly impressed by the practicality of this device and the ingenuity of its maker.
