The resulting virosome vaccine can attach to and fuse with host cells, but lacking genetic material, it can't replicate or harm the bird.
A promising alternative that is in an earlier stage of development involves the virosome vaccine. This trivalent vaccine, consisting of liposomes coated with influenza-derived proteins, has impressive immunogenicity in the elderly, she said.
in December 2013, which will fund the development of a virosome vaccine technology licensed from Mymetics Corp.
To overcome those problems, Kapcyznski and his colleagues at the Southeast Poultry Research Laboratory in Athens, Georgia, developed what's known as a nonreplicating virosome vaccine.
The virosome vaccine is composed of liposomes, water insoluble spheres encased in lipid layers.
In one study, day-old chicks were divided into three groups: a control group, which received saline solution; a group that received live-virus vaccine; and a group that received the virosome vaccine. Two weeks later, birds were challenged with a lethal dose of the virus.
The next step for Kapczynski and his colleagues is to determine whether the virosome vaccine can protect a typical commercial flock, which is exposed to various production and environmental stresses, such as other illnesses and temperature fluctuations.
The MACIVTVA project, which stands for "Manufacturing process for Cold-chain Independent Virosome-based Vaccines" will run 3.5 years and brings together global expertise in the field of virosome vaccines, manufacturing, spray drying, freeze drying and analytical techniques from the pharma industry.
