Avian Flu Vaccine Ready for Human Testing !!!

According to this report some poor soul is going to be unlucky enough to undergo human testing of the avian flu vaccine, I would hate to be the one needing money bad enough to submit myself as a guinee pig for this testing

volunteers will be vaccinated using an alternative to a needle. Instead, a handheld device will blast harmless, microscopic gold particles coated in the vaccine into the upper arm at supersonic speeds.

at least they dont use needles anymore

sorry to mods i didnt post this in the avian flu forum

Actually this forum is fine as it brings to the forefront a new wave in vaccine technology ie. "DNA vaccines" The website below hosted at the University of California at San Francisco is a good overall primer into this technology and gives some indication to DNA vaccines in the pipeline. It does hold the greatest promise in the battle to develop an HIV vaccine.

DNA vaccines are usually circular plasmids that include a gene encoding the target antigen (or antigens) under the transcriptional control of a promoter region active in human cells. The coding region of the inserted gene is followed by transcription termination and polyadenylation sequences. To permit selection of plasmid-containing bacteria during the production process, the plasmid also contains an antibiotic resistance gene with a bacterial origin of replication. DNA is generally less costly to produce than peptide or protein vaccines, and is chemically stable under a variety of conditions. DNA vaccines are generally administered intramuscularly, using either a needle and syringe or a needle-free injector. DNA vaccines were first tested in human beings with HIV infection,(1) and subsequently in uninfected people as preventive vaccines against HIV(2,3) and malaria.(4) While immune responses to DNA alone have been relatively weak in humans, combination with adjuvants or with recombinant viral vectors in prime-boost approaches have resulted in appreciable HIV-specific CD8 responses(5) and have induced protective responses in primate models (see below).

testing would constitute a possible failure or harsh side effect the result would further the cause of medicine but when dealing with DNA the possibilities are endless
