Palese’s laboratory is certainly one of three totally different analysis teams at Mount Sinai exploring a common flu vaccine and certainly one of quite a few efforts below approach principally in academia, biotech corporations and NIH. A handful of main pharmaceutical corporations are supporting common flu vaccine analysis, together with GlaxoSmithKline; Janssen Vaccines, a division of Johnson & Johnson; and Sanofi.
Palese’s staff has developed a common flu vaccine that’s now within the first part of testing in people, with assist from GSK and the Gates Basis. “What adjustments within the influenza virus from 12 months to 12 months is the hemagglutinin (HA),” Palese defined, “which is the most important protein in opposition to which we make an immune response.”
The HA includes a head and a stalk. “When our immune system sees a flu virus, it makes antibodies in opposition to the pinnacle,” he stated. Palese’s vaccine goals to stimulate antibodies that bind to the extra “conserved” areas on the stalk and which stay the identical yearly and are widespread to most seasonal flu viruses. “We need to redirect the physique’s immune response to the stalk.”

A distinct strategy to the common vaccine is below approach at FluGen, a biotech agency in Madison, Wisconsin. Backed by each authorities and VC funding, the corporate is working with expertise first found on the College of Wisconsin-Madison by Dr. Yoshihiro Kawaoka and Dr. Gabriele Neumann and solely licensed to FluGen. “Our vaccine, known as RedeeFlu, relies on a premise that claims, What occurs should you take a [naturally occurring] ‘wild-type’ of flu virus and modify it to contaminate the human physique however do not enable it to duplicate and trigger sickness?” stated Boyd Clarke, government chairman of FluGen. (Coincidentally, his maternal grandfather died within the 1918 flu pandemic.)
Final October, FluGen introduced it was awarded $14.four million by the Division of Protection to conduct human medical problem trials with RedeeFlu. In these research, half of the contributors can be vaccinated and half will obtain a placebo, however all will subsequently be contaminated with an influenza virus. “We need to see if the vaccine prevents sickness and replication of the virus,” Clarke stated. “Primarily based on preclinical trials, we now have cause to be optimistic.”
On one other entrance, this 12 months the Human Vaccines Undertaking, a New York-based nonprofit consortium of educational, authorities and business medical researchers, is launching the Common Influenza Vaccine Initiative. “The purpose is to grasp immunity to the flu after which convert that right into a common flu vaccine,” stated Dr. James Crowe, a pediatric infectious illnesses doctor at Vanderbilt College Medical Middle in Nashville, Tennessee, and the director of UIVI. Much like Palese’s strategy, UIVI is focusing on the extra secure stalk area of the HA protein.
Though Crowe is devoted to the eventual discovery of a common vaccine, he additionally needs to deal with enhancing present vaccines. “The joy within the area is making higher vaccines for strains which can be killing folks proper now,” he stated. “Even modest enhancements would save hundreds of lives.”
