Shake Shack is expanding its vaccination promotion in New York to all Shack locations in the U.S., excluding airports, stadiums and ballparks, to encourage even more Americans to get vaccinated against COVID-19. Starting May 21 through June 12, Shake Shack is offering free Crinkle Cut Fries with the purchase of any burger or chicken sandwich by showing proof of vaccination in-store.

The promotion kicked off in New York last week and is part of Shake Shack’s ongoing commitment to support the communities in which it operates.

“Shake Shack has always prioritized taking care of our communities and we’re proud to be part of their recovery, helping get more people vaccinated and back to gathering again!” says CEO Randy Garutti, CEO.
