At this time, CDC is participating in a broad inter-agency partnership coordinated by BARDA (https://www.phe.gov/Preparedness/planning/nivms/Pages/default.aspx) that supports the advanced development of new and better flu vaccines. These efforts already have yielded important successes (https://www.cdc.gov/flu/prevent/advances.htm#vaccine-advances). Part of this effort is the eventual development of a “universal vaccine” that would offer better, broader and longer-lasting protection against seasonal influenza viruses as well as novel influenza viruses. This task poses an enormous scientific and programmatic challenge, but a number of government agencies and private companies already have begun work to advance development of a universal flu vaccine.
