Learn how immunizing a critical portion of a community protects most members of the community.
The 2009 outbreak of a new strain of H1N1 influenza A demonstrated that continuing vigilance, planning, and strong public health research capability are essential defenses against emerging health threats.
Past research on H5N1 (bird flu) as well as other influenza viruses with potential to create pandemics prepared NIAID scientists to respond to this newest influenza threat. Researchers expanded and refocused projects to include studies of the course of the virus, the origin of the virus, H1N1-infected patients, and a preventive vaccine. Many of these studies involve collaborations with other federal agencies, academia, and the private sector. Scientific findings continue to shed light on the mysteries of influenza, and will help researchers create better, faster vaccine production techniques, and better treat severely ill people.
