"We are committed to honoring vaccination appointments that have been scheduled in our system, and our team members are reaching out to all patients affected to attempt to accommodate them," the company continued. "If supply does not allow us to vaccinate some of these patients, we will prioritize them for appointments as additional vaccine inventory is available. We apologize for the inconvenience." The company did not respond to multiple requests on how many people the glitch impacted, though hundreds of members of the "Chicago Vaccine Hunters" Facebook group posted and commented that they were experiencing that same issue. Users have repeatedly complained about the Walgreens appointment sign-up process, some on social media calling the latest glitch "a mess" and "so frustrating."
