An influenza vaccine that protects against death and serious complications from different strains of flu is a little closer to reality, Saint Louis University vaccine researchers have found.
"This is a significant first step in developing a universal vaccine to help protect against pandemic influenza," said Robert Belshe, M.D., director of the Saint Louis University Center for Vaccine Development.
Belshe, the lead researcher who studied a vaccine made with proteins from strains of influenza viruses A and B, presents his findings on April 27 at the National Foundation for Infectious Disease Conference for Vaccine Research in Baltimore.
Currently drug companies manufacture a different flu vaccine each year to match the strains of influenza that researchers predict will circulate. Adding a universal influenza vaccine to a seasonal vaccine would help improve protection against strains of influenza as they change each year.
"Novel vaccines, capable of inducing long-lasting, broad immunity against divergent strains, including potential pandemic viruses, are highly desirable," Belshe said.
In the study, 377 healthy adults received three injections of a universal influenza vaccine, known as Bivalent Influenza Peptide Conjugate Vaccine (BIPCV), over a six month period.
Researchers found that a low dose of the vaccine is well tolerated and safe, Belshe said. It addition, the low dose vaccine evoked an immune response – high antibody titers – that is similar to levels associated with protecting small animals infected with influenza from serious disease and death. More testing is needed, Belshe added.
The research also is significant in light of the search for a vaccine to protect against a deadly influenza pandemic, which is a global outbreak of the disease that spreads quickly with lethal consequences.
Established in 1836, Saint Louis University School of Medicine has the distinction of awarding the first medical degree west of the Mississippi River. The school educates physicians and biomedical scientists, conducts medical research, and provides health care on a local, national and international level. Research at the school seeks new cures and treatments in five key areas: cancer, liver disease, heart/lung disease, aging and brain disease, and infectious disease.

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...
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...
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...

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...
