For today only, participating Taco Bell locations in California will be shelling out a free Nacho Cheese Doritos Locos Taco to customers who present their COVID-19 vaccination card.

The promo is part of the Vax for the Win incentive program, which encourages individuals to get vaccinated for the COVID-19 virus. Think of it as Taco Bell's thank you to those that are doing their part to help make California safe as much of the state fully reopens.
