An avian influenza H7 DNA priming vaccine is safe and immunogenic in a randomized phase I clinical trial
Avian influenza: A vaccine for a deadly emergent strain A vaccine candidate to treat a deadly subtype of avian influenza was shown to induce protective antibodies in initial clinical trials.

| Sumario: | Avian influenza: A vaccine for a deadly emergent strain A vaccine candidate to treat a deadly subtype of avian influenza was shown to induce protective antibodies in initial clinical trials. As of March 2017, avian influenza strain A/H7N9 has killed 497 people since 2013, with 1349 confirmed cases. Julie Ledgerwood and her team from the United States’ National Institutes of Health in collaboration with colleagues at the Centers for Disease Control and Prevention tested their two-stage vaccine protocol in humans, showing it to be effective and safe. The vaccine consists of an initial injection of viral DNA, which ‘primes’ the immune system to the pathogen, followed by a follow-up injection of an inactivated purified viral protein, which further boosts the host’s production of protective antibodies. The study shows the viability of this vaccine regimen and suggests further investigation into its appropriateness for treating avian influenza in humans. |
