CDC: Too Early to Predict Future of H7N9 Outbreak

Source: Infectious Disease News


The Centers for Disease Control and Prevention (CDC) is closely watching the outbreak of the novel influenza A (H7N9) virus in the Southern Hemisphere, and it is concerned because it does not expect any immunity to the virus if human-to-human transmission occurs, according to Michael Shaw, associate director of Laboratory Science for the center’s Influenza Division. As of April 9, the virus has infected 28 people and killed eight in China. The CDC is pursuing a vaccine for H7N9, which has been found in pigeons, chickens and quail, all farm-raised animals grown for commercial purposes. In addition to egg-based vaccine manufacturers, Novartis is working on a cell-based vaccine and MedImmune is working on a live-attenuated vaccine. “We’re not going to leave anything to chance,” Shaw said. “We are going to try everything we can think of.”
