65+ Flu Defense is a project of Immunize.org and CSL Seqirus. This collaboration aims to reach health care providers with information, tools, and resources they need to better communicate the impact of flu and its complications in older adults, and to proactively discuss flu vaccination with their patients age 65 and older.

Immunize.org works to increase immunization rates and prevent disease by creating and distributing educational materials for health professionals and the public that enhance the delivery of safe and effective immunization services. Immunize.org also facilitates communication about the safety, efficacy, and use of vaccines within the broad immunization community of patients, parents, healthcare organizations, and government health agencies.

CSL Seqirus, as the second-largest influenza vaccine provider in the world, is a major contributor to the prevention of influenza globally and a transcontinental partner in pandemic preparedness. CSL Seqirus operates state-of-the-art production facilities in the U.S., the UK, and Australia, and manufactures influenza vaccines using both egg-based and cell-based technologies. It has leading R&D capabilities, a broad portfolio of differentiated products, and a commercial presence in more than 20 countries.
