National partners VA and Walgreens are providing free flu shots to enrolled Veterans of the VA health care system. Now through March 31, 2020, go to any Walgreens pharmacy and show your Veterans Health Identification Card and another form of photo ID. No appointment is required. Walgreens will electronically send vaccination information to the VA and your immunization record will be updated in your VA electronic health record.
