Rapid and Durable Protection Against Ebola Virus With New Vaccine Regimens

09.09.2014

NIH Scientists and Collaborators Report Positive Results in Monkeys

WHAT:
One shot of an experimental vaccine made from two Ebola virus gene segments incorporated into a chimpanzee cold virus vector (called chimp adenovirus type 3 or ChAd3) protected all four macaque monkeys exposed to high levels of Ebola virus 5 weeks after inoculation, report National Institutes of Health (NIH) scientists and their collaborators. The ability of the ChAd3 Ebola virus vaccine to elicit rapid protection in monkeys is notable as the world health community battles an ongoing Ebola virus disease outbreak in West Africa. While the protective effects of the single shot waned over time, two out of four inoculated animals were protected when challenged with Ebola virus 10 months after vaccination.

The research team, headed by Nancy J. Sullivan, Ph.D., of the National Institute of Allergy and Infectious Diseases Vaccine Research Center, also demonstrated increased levels of durable protection using an additional vaccine. They inoculated four macaques first with the ChAd3 Ebola vaccine, then 8 weeks later with a booster vaccine containing Ebola virus gene segments incorporated into a different vector (a poxvirus). Ten months after the initial inoculation, four out of four animals that received both shots were fully protected from infection with high doses of Ebola virus, demonstrating that the prime-boost regimen resulted in durable protection.


The research team included scientists from Okairos, a Swiss-Italian biotechnology company now part of GlaxoSmithKline, and the U.S. Army Medical Research Institute of Infectious Diseases. The experimental ChAd3 Ebola vaccine used in these non-human primate studies is the same one currently being tested in an early-stage human clinical trial at the NIH in Bethesda, Maryland.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
