Seasonal Influenza Vaccine Toolkit

The Centers for Disease Control and Prevention recommends anyone six months and older get an annual flu shot, unless they have a medical condition that prevents them from getting one. While it's not possible to say with certainty what will happen during this flu season, CDC believes it's likely that flu viruses and the virus that causes COVID-19 will both be active.

This toolkit provides communicators across the Military Health System with important information about the flu vaccine from the CDC and TRICARE to share with patients and health care professionals. Our goals:

  • Educate beneficiaries, civilians, contractors, volunteers, and MHS and Department of Defense health care providers and staff on the importance of vaccines. 
  • Equip MHS and DOD health care providers and staff with information and resources needed to direct the successful distribution of the flu vaccine. 


Influenza or “flu” is a highly contagious respiratory illness that can potentially result in hospitalization or death. A yearly flu vaccination is the best way to reduce influenza illnesses, doctor visits, missed attendance at work or school, and prevent flu-related hospitalizations. The seasonal influenza vaccine is designed to protect against the influenza viruses determined by the World Health Organization (WHO) to be the most likely to spread and cause illness among people during the influenza season. The U.S. Food and Drug Administration makes the final decision about vaccine viruses included in influenza vaccines in the United States.
