Dog Virus To Become Potent Vaccine
A canine virus could be the springboard for developing a super potent human vaccine, thanks to a University of Georgia discovery.
“We can use this virus as a vector (delivery vehicle) for all kinds of pathogens that are difficult to vaccinate against,” said Biao He, principal study investigator and professor of infectious diseases at University of Georgia College of Veterinary Medicine.
Georgia researchers said this virus could also help protect humans against diseases that have eluded vaccine efforts for decades, the journal Public Library of science ONE reported.
Although harmless in humans, parainfluenza virus 5, or PIV5, is believed to contribute to upper respiratory infections in dogs. It is a common target for canine vaccines designed to prevent kennel cough.
PIV5 does not cause disease in humans, as our immune system is able to recognise and destroy it, according to a Georgia statement.
“We have developed a very strong H5N1 flu vaccine with this technique, but we are also working on vaccines for HIV, tuberculosis and malaria,” added He.
By placing antigens from other viruses or parasites inside PIV5, it effectively becomes a delivery vehicle that exposes the human immune system to important pathogens and allows it to create the antibodies that will protect against future infection.
This approach not only ensures full exposure to the vaccine but also is much safer because it does not require the use of attenuated, or weakened, pathogens.
For example, an HIV vaccine delivered by PIV5 would contain only those parts of the HIV virus necessary to create immunity, making it impossible to contract the disease from the vaccine.
Using viruses as a delivery mechanism for vaccines is not a new technique, but previous efforts have been fraught with difficulty.
If humans or animals already possess a strong immunity to the virus used for delivery, the vaccine is unlikely to work, as it will be destroyed by the immune system too quickly.

The idiets from the west have realised that the HIV is too slow to wipe out the intended populations as expected! Therefore, they want to bring a more effective Virus to achieve their devilish objectives!
After all they are just trying to impliment what idiets like Thomas Malthius proposed that in order to reduce the world population, especially for poor countries, introduce wars in their communities, calamities and any other device that will keep them on check!
Ala ba Sondashi twafweni because nothing good will come from the west especially from america! God have mercy!

The West always plays with people’s minds. Now they are talking about another drug because they know that Africans are desperate for HIV drugs. For all I know, they want to wipe out african race. True, let Sondashi drug be sold in the chemists.

The HIV virus they created in their develish labs is not enough, now they want to create super rabbies for Africans. Bushe bafikala aba babashani kanshi? Filya fine bamyangana pa misula efyo namaano yabo yaba.
