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.
New Strategies in Battle Against Antibiotic Resistance

Over the past year, the problem of antibiotic resistance has received considerable attention, with concerns being raised by scientists, clinicians, public health officials, and many others around the globe. These bacteria are found not only in hospitals, but in a wide range of community settings. In the United States alone, antibiotic-resistant bacteria cause roughly 2 million infections per year, and 23,000 deaths [1].
In light of such daunting statistics, the need for action at the highest levels is clear, as is demonstrated by an Executive Order issued today by the President. Fighting antibiotic resistance is both a public health and national security priority. The White House has joined together with leaders from government, academia, and public health to create a multi-pronged approach to combat antibiotic resistance. Two high-level reports released today—the White House’s National Strategy for Combating Antibiotic-Resistant Bacteria (CARB) and the complementary President’s Council of Advisors on Science and Technology (PCAST) Report to the President on Combating Antibiotic Resistance—outline a series of bold steps aimed at addressing this growing public health threat.
