Man’s Best Friend: Common Canine Virus May Lead To New Vaccines For Deadly Human Diseases

Posted Nov 27 2012 6:33pm

Researchers at the University of Georgia have discovered that a virus commonly found in dogs may serve as the foundation for the next great breakthrough in human vaccine development.

Although harmless in humans, parainfluenza virus 5, or PIV5, is thought to contribute to upper respiratory infections in dogs, and it is a common target for canine vaccines designed to prevent kennel cough. In a paper published recently in PLOS ONE, researchers describe how this virus could be used in humans to protect against diseases that have eluded vaccine efforts for decades.

“We can use this virus as a vector for all kinds of pathogens that are difficult to vaccinate against,” said Biao He, the study’s principal investigator and professor of infectious diseases in UGA’s College of Veterinary Medicine. “We have developed a very strong H5N1 flu vaccine with this technique, but we are also working on vaccines for HIV, tuberculosis and malaria.”
