Candidate H7N9 avian flu vaccine works better with adjuvant

(NIH/National Institute of Allergy and Infectious Diseases) An experimental vaccine to protect people against H7N9 avian influenza prompted immune responses in 59 percent of volunteers who received two injections at the lowest dosage tested, but only if the vaccine was mixed with adjuvant -- substance that boosts the body's response to vaccination. Without adjuvant, immune responses produced by the investigational vaccine were minimal regardless of vaccine dosage, according to findings from a clinical trial sponsored by NIAID, part of NIH.
