An innovative vaccine technology makes use of reengineered salmonella to deliver protective immunity. If such recombinant attenuated salmonella vaccines or RASVs can be perfected, they hold the promise of safe, lost-cost, orally administered defenses against viral, bacterial, fungal and parasitic infections.
In a new study, lead author Karen Brenneman and her colleagues at the Biodesign Institute at Arizona State University, propose an improved method of screening salmonella vaccines in small animal studies and enhancing their effectiveness in humans.
