The American Red Cross is asking healthy donors of all blood types to give blood.

The blood donations will help ensure a strong blood supply as the U.S. braces for flu season during the COVID-19 pandemic.

If you’ve received a flu shot, you can give blood. The Red Cross says there is no waiting period to give blood or platelets after receiving a flu shot as long as you’re symptom-free and fever-free.

The American Red Cross will email a $5 Amazon.com gift card to those who come in and donate blood between Oct. 15 and Nov. 11. Plus, those who donate in October are automatically entered to win a $1,000 Amazon.com gift card.

You can make an appointment to donate blood by downloading the Red Cross Blood Donor App, visiting www.RedCrossBlood.org, or calling 1-800-Red Cross.
