Candidate H7N9 avian flu vaccine works better with adjuvant
An experimental vaccine to protect people against H7N9 avian influenza prompted immune responses in 59 percent of volunteers who received two injections, but only if the vaccine was mixed with adjuvant—a substance that boosts the body’s response to vaccination. Without adjuvant, immune responses produced by the investigational vaccine were minimal regardless of vaccine dosage. The findings are from a clinical trial sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. More details about the trial, which enrolled 700 people, are available: http://www.niaid.nih.gov/news/ newsreleases/2014/Pages/ H7N9adjuvant.aspx.
